State whether the given measurements determine zero, one, or two triangles. C = 37°, a = 16, c = 14
Answers
Two triangles: b ≈ 2.62 or 22.94
Answer:
sides are a = 16 c = 14 b =22.96
angles are A = 43.39° B = 99.61° C = 37°
Step-by-step explanation:
using sine law of triangle,
[tex]\frac{sin A}{a} = \frac{Sin B}{b}= \frac{sinC}{c}[/tex]
using,
[tex]\frac{sin A}{a} = \frac{sinC}{c}[/tex]
given that,
C= 37° a = 16 c = 14
now,
[tex]\frac{sin A}{16} = \frac{sin37^o}{14}[/tex]
sin A = 0.687
A = 43.39°
hence B = 180° - (43.39° + 37°)
B = 99.61°
[tex]\frac{sin 43.39^o}{16} = \frac{sin99.61^o}{b}[/tex]
b = 22.96
Hence, there will be only one triangle which will form and there
sides are a = 16 c = 14 b =22.96
angles are A = 43.39° B = 99.61° C = 37°

What is the value of x in the equation 2(x+3)=4(x-1)
Answers
Step 1: Distribute the 2 to numbers and variables inside parentheses
(2 × x) + (2 × 3) = 4 (x - 1)
2x + 6 = 4 (x - 1)
Step 2: Distribute the 4 to numbers and variables inside parentheses
2x + 6 = (4 × x) + ( 4 × - 1)
2x + 6 = 4x+ (-4)
2x + 6 = 4x- 4
Step 3: Combine like terms (x's go with x's) by subtracting 2x to both sides
(2x - 2x) + 6 = (4x - 2x) - 4
6 = 2x - 4
Step 4: Combine like terms by adding 4 to both sides
6 + 4 = 2x - 4 + 4
10 = 2x
Step 5: Isolate x by dividing 2 to both sides
10 ÷ 2 = 2x ÷2
5 = x
x = 5
To check: plug 5 into all the x's of the equation
2(x+3)=4(x-1)
2(5+3)=4(5-1)
2(8) = 4(4)

Give your answer in standard form.
Answers
The result of the calculation (6 * 10^2) / (3 x 10^-5) is 2 x 10^7, when written in standard form.
Explanation:To solve the equation (6 * 10^2) / (3 * 10^-5), we first simplify both sides. 6 * 10^2 equates to 600, and 3 x 10^-5 equates to 0.00003. Therefore, we are left with the simple division: 600 / 0.00003.
To divide these two numbers, you would get a result of 20000000. However, the problem asks for the answer in standard form. Standard form is a way of writing numbers that are too large or too small to be conveniently written in decimal form. In standard form, 20000000 is represented as 2 x 10^7.

Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope. (5 points)
Answers
Answer: The answers are given below.
Step-by-step explanation: Given that the graph shows the relationship between the number of months different students practiced boxing and the number of matches they won:.
Part A : We are to find the approximate y-intercept of the line of best fit and state what does it represent.
From the graph, we note that
at x = 0, the value of y is approximately 3.
So, the approximate y -intercept of the line of best fit is 3.
It represents that before starting the matches, the students can win 3 matches without any practice.
Part B : We are to write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice.
From the graph, we note that the line of best fit passes through the points (2, 7) and (9, 18).
So, the slope of the line of best fit will be
[tex]m=\dfrac{18-7}{9-2}=\dfrac{11}{7}.[/tex]
Therefore, the slope-intercept form of the equation of the line of best fit is given by
[tex]y=mx+c\\\\\Rightarrow y=\dfrac{11}{7}x+3.[/tex]
Thus, the number of matches that could be won after 13 months of practice is
[tex]y=\dfrac{11}{7}\times13+3=23.42.[/tex]
That is, students can win 23 matches with 13 months of practice.
The approximate y-intercept is 35.25 and it represents the starting point on the graph. The equation for the line of best fit is y = 0.09x + 35.25. After 13 months of practice, the prediction is that the student could win approximately 36 matches.
Explanation:Part A: The approximate y-intercept of the line of best fit is 35.25. The y-intercept represents the number of matches a student would have won without any months of practice. In other words, it is the initial starting point on the graph when the number of months practiced is zero.
Part B: The equation for the line of best fit in slope-intercept form is y = 0.09x + 35.25. To predict the number of matches after 13 months of practice, we substitute the value of x (number of months) into the equation. Therefore, y = 0.09(13) + 35.25 = 36.42.
Therefore, the prediction is that the student could win approximately 36 matches after 13 months of practice.
the sum of three consecutive natural numbers is 1086
Answers
Answer:
361. 362,363
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 1086.
We assign X to the first integer. Since they are consecutive, it means that the 2nd number will be X+1 and the third number will be X+2 and they should all add up to 1086. Therefore, you can write the equation as follows:
X + X + 1 + X + 2 = 1086
To solve for X, you first add the integers together and the X variables together. Then you subtract 3 from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 1086
3X + 3 = 1086
3X + 3 - 3 = 1086 - 3
3X = 1083
3X/3 = 1083/3
X = 361
Which means that the first number is 361, the second number is 361+1 and third number is 361+2. Therefore, three consecutive integers that add up to 1086 are:
361
362
363
Follow below steps;
The question asks to find three consecutive natural numbers that add up to 1086. Let's denote the smallest of these three numbers as n. Then, the next two numbers can be represented as n + 1 and n + 2. The sum of these three numbers is:
n + (n + 1) + (n + 2) = 1086
Combining like terms, we get:
3n + 3 = 1086
Subtracting 3 from both sides, we get:
3n = 1083
Dividing both sides by 3, we find:
n = 361
So the three consecutive numbers are 361, 362, and 363, and they indeed sum up to 1086:
361 + 362 + 363 = 1086

Step-by-step explanation:
A. y-Intercept of ƒ(x)
ƒ(x) = x² - 4x + 3
f(0) = 0² - 4(0) + 3 = 0 – 0 + 3 = 3
The y-intercept of ƒ(x) is (0, 3).
If g(x) opens downwards and has a maximum at y = 3, it's y-intercept is less than (0, 3).
Statement A is TRUE.
B. y-Intercept of g(x)
Statement B is FALSE.
C. Minimum of ƒ(x)
ƒ(x) = x² - 4x + 3
a = 1; b = -4; c = 3
The vertex form of a parabola is
y = a(x - h)² + k
where (h, k) is the vertex of the parabola.
h = -b/(2a) and k = f(h)
h = -b/2a = -(-4)/(2×1 = 2
k = f(2) = 2² - 4×2 + 3 =4 – 8 +3 = -1
The minimum of ƒ(x) is -1. The minimum of ƒ(x) is at (2, -1).
Statement C is FALSE.
D. Minimum of g(x)
g(x) is a downward-opening parabola. It has no minimum.
Statement D is FALSE
The height (in feet) of a rocket launched from the ground is given by the function f(t) = -16t2 + 160t. Match each value of time elapsed (in seconds) after the rocket’s launch to the rocket's corresponding instantaneous velocity (in feet/second).
t = 2 96 t = 3 -64 t = 4 32 t = 5 0 t = 6 -128 t = 7 -32 t = 8 t = 9
Answers
Answer:
t = 2 s= 96
t = 3 s = 64
t = 4 s= 32
t= 5 s = 0
t= 6 s = -32
t = 7 s = -64
t = 8 s = -96
t= 9 s = -128
Step-by-step explanation:
We have the equation of the position of the rocket as a function of time t.
[tex]f(t) = -16t^2 + 160t[/tex]
The instantaneous velocity of the rocket as a function of time is given by the derivation of the position with respect to time.
So
[tex]S(t)=\frac{df(t)}{dt} = -2*16t + 160\\\\S(t) = -32t+160[/tex]
[tex]s(1) = -32(1)+160=128\ ft/s\\\\s(2) = -32(2)+160=96\ ft/s\\\\s(3) = -32(3)+160=64\ m/s\\\\s(4) = -32(4)+160=32\ m/s\\\\s(5) = -32(5)+160=0\ m/s\\\\s(6) = -32(6)+160=-32\ m/s\\\\s(7) = -32(7)+160=-64\ m/s\\\\s(8) = -32(8)+160=-96\ m/s\\\\s(9) = -32(9)+160=-128\ m/s[/tex]
So
t = 2 s= 96
t = 3 s = 64
t = 4 s= 32
t= 5 s = 0
t= 6 s = -32
t = 7 s = -64
t = 8 s = -96
t= 9 s = -128
Final answer:
To match time values with the rocket's velocity after launch, we take the derivative of the position function f(t) to obtain the velocity function v(t) = -32t + 160. The corresponding velocity for each time value can be calculated by plugging the time into the velocity function.
Explanation:
The height of a rocket as a function of time after launch is given by f(t) = -16t2 + 160t, and we are asked to match each value of time elapsed with the rocket's corresponding instantaneous velocity. To find the instantaneous velocity, we need to take the derivative of the position function with respect to t, which represents time in seconds. The derivative of f(t) with respect to t is f'(t) = -32t + 160. This is the velocity function v(t), which gives the instantaneous velocity at any given time t.
At t = 2, the velocity v(2) = -32(2) + 160 = 96 feet/second.
At t = 3, the velocity v(3) = -32(3) + 160 = 64 feet/second.
At t = 4, the velocity v(4) = -32(4) + 160 = 32 feet/second.
At t = 5, the velocity v(5) = -32(5) + 160 = 0 feet/second. (This is the point at which the rocket reaches its peak and starts descending.)
At t = 6, the velocity v(6) = -32(6) + 160 = -32 feet/second (indicating the rocket is now falling back to the ground).
The values for t = 7, t = 8, and t = 9 can be calculated in a similar manner using the velocity function v(t).

Step-by-step explanation:
There are two ways to do this. The simplest way is to realize that the exterior angle (45x) = the sum of the two remote interior angles.
25x and 57 + x
45x = 25x + 57 + x Subtract 26x from both sides.
45x - 26x = 25x - 25x + 57 Combine
19x = 57 Divide by 20
19x/19 = 57/19 Do the division
x = 3
===================================
Second method.
The supplement of the 45x angle is 180 - 45x
Now add the three angles together.
180 - 45x + x + 57 + 25x = 180 Combine like terms.
180 + 57 - 45x + x + 25x = 180
237 - 19x = 180 Subtract 237 from both sides.
- 19 x = 180 - 237 Combine the right side
- 19x = -57
x = 3

Using kinematic equations, we determine that the accelerating police car will catch up to the speeding car moving at a constant velocity in 20 seconds.
Explanation:To solve the problem of when a police car accelerating at 4 m/s² will catch up to a speeding car moving at a constant velocity of 40 m/s, we can use kinematic equations for motion. The speeding car's position over time is given by the equation x = vavgt, where vavg = 40 m/s is the average velocity. Since the police car starts from rest (vo = 0) and has an acceleration of 4 m/s², its position over time is given by the equation x = 0.5at².
We set the displacement of both cars equal to each other to find the time (t) when they are at the same position:
40t = 0.5(4)t².
This simplifies to: 40t = 2t², and by further simplification, we find that t = 20 seconds. Thus, it will take the police car 20 seconds to catch up to the speeding car.

The function f(x) = -2x5 + x3 − 7x is an odd function. Which rule is satisfied by this function?
Answers
An odd function like f(x) = -2x^5 + x^3 − 7x satisfies the property that y(x) = -y(-x), which indicates that the function is symmetric around the origin. The multiplication of odd and even functions results in an odd function, and the integral of an odd function over all space equals zero due to the cancelation of negative and positive areas.
Explanation:The rule satisfied by the function f(x) = -2x^5 + x^3 − 7x, which is an odd function, is that y(x) = −y(-x). Essentially, what that means is that when you plug -x into the function, the sign of the result will be the opposite of the result of plugging x into the function. This rule manifests itself graphically as a kind of symmetry: odd functions are symmetric around the origin. They are produced by reflecting the graph of y(x) across the y-axis and then the x-axis. In contrast to even functions, which have symmetry around the y-axis, odd functions display this kind of 'rotational' symmetry.
Also worth noting, multiplying an odd function by an even function always yields an odd function. For instance, x*e^-x² is an odd function because x is an odd function and e^-x² is an even function. Additionally, the property of odd functions to integrate over space to zero is particularly useful, as they effectively 'cancel out' negative and positive areas along the x-axis.

g = 3/7 * b
g+64 = b
Then fill in one in the other and simplify:
3/7 b + 64 = b =>
4/7 b = 64
b = 64 * 7/4 = 112
g = 112 * 3/7 = 48
Final answer:
By setting up equations with the given proportions and difference in numbers, we can calculate that there are 112 boys and 48 girls in the field, totaling 160 children.
Explanation:
To solve the problem of how many children are in the field, we need to set up an equation based on the information given. It states that there are 3/7 girls there are boys, and that there are 64 more boys than girls. Let's define the number of boys as B and the number of girls as G. According to the problem, B = G + 64 and G = (3/7) * B.
To find the solution, we need to substitute G from the second equation into the first to get B = (3/7) * B + 64. Simplifying this equation, we multiply both sides by 7 to get rid of the fraction 7B = 3B + 448. Then we subtract 3B from both sides yielding 4B = 448. Dividing both sides by 4 gives us B = 112. Now that we have the number of boys, we can find the number of girls using the second equation: G = (3/7) * 112 = 48. Finally, we add the number of girls and boys to find the total number of children in the field 112 + 48 = 160.
How much of a radioactive kind of ruthenium will be left after 6 days if the half-life is 3 days and you start with 80 grams?
Answers
After 6 days, 20 grams will be left from the original 80 grams.
The half-life is the time it takes for half of the radioactive substance to decay. In this case, the half-life of ruthenium is given as 3 days. Starting with an initial quantity of 80 grams, we can calculate the remaining quantity after each half-life period.
After the first 3 days, one half-life will have passed, and half of the 80 grams will have decayed:
80 g / 2 = 40 g remaining.
After the second 3 days, another half-life will have passed, so another half of the remaining 40 grams will have decayed:
40 g / 2 = 20 g remaining.
Therefore, after 6 days, which corresponds to two half-life periods, 20 grams of the radioactive isotope of ruthenium will be left.
whats the difference between communitive and associative property
Answers
For this case we have that by definition, the associative property states that:
The order in which the factors (or addends) are associated does not alter the product (or the sum).
On the other hand, the commutative property states that:
The order of the factors (or addends) does not alter the product (or the sum).
What is the MAD for 4,5,6,1? Please help I am really confused!
Answers
Answer:
MAD = 1.5.
Step-by-step explanation:
MAD is the Mean Absolute Deviation.
The MAD is a measure of the spread of the data.
The mean of these numbers is (1 + 4 + 5 + 6) / 4
= 16/4 = 4.
Now you subtract this from the individual values and take the absolute values:
1 - 4 = -3 (absolute value = 3).
4-4 = 0
5-4 = 1
6-4 = 2.
Adding 0+1+2+3 = 6.
The MAD = 6 / 4 = 1.5.
Answer:
