This table lists the coordinates of points on a line. What is the y-intercept of the line?
x -2 -1 0 1 2 3
y 16 12 8 4 0 -4
Answer:
The line intercepts the y-axis and [tex]y = 8[/tex]
Step-by-step explanation:
The intersection on the y-axis of a line is found to be [tex]x = 0[/tex].
That is, the intercept with the y-axis is the value of the function when x is equal to zero.
In this case we know the following points of the function:
x : -2 -1 0 1 2 3
y : 16 12 8 4 0 -4
Note that when [tex]x = 0[/tex] then [tex]y = 8[/tex].
Therefore the line intercepts the y-axis and [tex]y = 8[/tex]

What is p(t)=-log_10(t)^.5 in exponential form
Answer:
[tex]10^{-p\left(t\right)}=t^{\left(0.5\right)}[/tex]
Step-by-step explanation:
Given equation is [tex]p\left(t\right)=-\log_{10}t^\left(0.5\right)[/tex]
Now question says to write that in exponential form.
So we can use the following conversion formula:
[tex]\log_ca=b\ \Rightarrow c^b=a[/tex]
[tex]p\left(t\right)=-\log_{10}t^\left(0.5\right)[/tex]
[tex]-p\left(t\right)=\log_{10}t^\left(0.5\right)[/tex]
[tex]\log_{10}t^\left(0.5\right)=-p\left(t\right)[/tex]
Apply conversion formula
[tex]p\left(t\right)=-\log_{10}t^\left(0.5\right)\ \Rightarrow 10^{-p\left(t\right)}=t^{\left(0.5\right)}[/tex]
[tex]10^{-p\left(t\right)}=t^{\left(0.5\right)}[/tex]

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the number of parts he usually makes?
Answer:
The answer is 80%.
Step-by-step explanation:
During a certain day, a worker made 81 parts.
He usually does 45 parts per day.
Number of extra parts made = [tex]81-45=36[/tex]
The percent by which he increased the number of parts he usually makes can be given as = [tex]\frac{36}{45}\times100[/tex] = 80%
Therefore, on that day, the percent increased by 80%.
Answer:
Increase by 80%
Step-by-step explanation:
45 : 100%
81 : y
[tex]\frac{81}{45} :\frac{y}{100}[/tex]
y × 45 = 81 × 100
45y = 8100
45y ÷ 45 = 8100 ÷ 45
y = 180
180% - 100% = 80%
Increase by 80%

A restaurant did a survey among 200 customers to find their food preferences. The customers were asked about their preferences for pasta or rice. Out of the total 60 people who liked pasta, 20 also liked rice. There were 80 people who liked rice.
Part A: Summarize the data by writing the values that the letters A to I in the table below represent.
Like pasta Do not like pasta Total
Like rice A B C
Do not like rice D E F
Total G H I
Part B: What percentage of the survey respondents did not like either pasta or rice?
Part C: Do the survey results reveal a greater dislike for rice or pasta? Justify your answer.
Answer:
Below
Step-by-step explanation:
Part A:
Like Pasta / Like Rice: A = 20
Like Rice / Do not like Pasta: B = 60
Total: C = 80
Do not like rice / Like Pasta: D = 40
Do not like rice & Pasta: E = 80
Total F = 120
Total G = 60
Total H = 140
Total I = 200
Part B: Using the rule of three:
If 200 represents 100%, then how much 80 represents?
(80 * 100) / 200 = 40%
40% did not like pasta nor rice.
Part C:
From the survey we know that:
30% like rice, and 20% dislike pasta. So yes, the survey reveals a greater dislike for rice.

Answer:
B
Step-by-step explanation:
The surface area (A) of a sphere is
A = 4πr² ← r is the radius which we require
Given A = 2500π, then
4πr² = 2500π ( divide both sides by 4π )
r² = 625 ( take the square root of both sides )
r = 25
The volume (V) of a sphere is
V = [tex]\frac{4}{3}[/tex]πr³, and
[tex]\frac{V}{\pi }[/tex] = [tex]\frac{4}{3}[/tex]r³ = [tex]\frac{4}{3}[/tex] × 25³ , thus
[tex]\frac{V}{\pi }[/tex] = [tex]\frac{4}{3}[/tex] × 15625 ≈ 20833.33.. → B
Compare the algebraically expressed function f(x) = -8x2 + 4x + 2 to the function shown in the graph to determine which statement is true.
A) The algebraic function has a greater maximum value.
B) The algebraic function has a lower minimum value.
C) The graphed function has a greater maximum value.
D) The graphed function has a lower minimum value.
ANSWER
A) The algebraic function has a greater maximum value.
EXPLANATION
The given function is
[tex]f(x) = - 8 {x}^{2} + 4x + 2[/tex]
This can be rewritten as:
[tex]f(x) = - 8( {x - \frac{1}{4} })^{2} + \frac{5}{2} [/tex]
The maximum value of this function is 2.5
The maximum value of the graph is less that zero.
This means that that the maximum value of the algebraic function is greater than the maximum value of the graph.
Answer:
Option A.
Step-by-step explanation:
Algebraically expressed function is f(x) = -8x² + 4x + 2
As we know in a quadratic equation f(x) = ax² + bx + c, if a is negative then the vertex will be maximum.
and the maximum value will be represented by [tex]c-\frac{b^{2}}{4a}[/tex]
From the given quadratic equation
a = -8
b = 4 and c = 2
Now we place these values in the equation.
Maximum = [tex]2-\frac{4^{2}}{4(-8)}[/tex]
= 2 + 0.5
= 2.5
From the graph attached we can easily conclude that vertex of the parabola is less than 0.5
Therefore, algebraic function has the greater maximum value.
Option A. is the answer.

The prism below is made of cubes which measure of a foot on one side. What is the volume?
A. 12 cubic ft.
B. 4/3 cubic ft.
C. 10/3 cubic ft.
D. 36 cubic ft.
Answer:
the answer is B. 4/3 cubic ft.
Step-by-step explanation:
use the formula
V = LWH
using 1/3 for each calculation
length = 3 (1/3 ft)
width = 4 (1/3 ft)
height = 3 (1/3 ft)
then you substitute those dimension
V = (3/3 ft.) (4/3 ft.) (3/3 ft.)
V = (1 ft.) (4/3 ft.) (1 ft.)
V = 4/3 cubic ft

Answer:
8861 : 9495
Step-by-step explanation:
Ratio of income in 2001 to 2003:
53,166 : 56,970
Then, you can simplify by dividing both sides by 6:
8,861 : 9,495
Can't simplify anymore, Therefore this is the answer!
8861 : 9495
Hope I helped! Have a good day :)
Answer:
[tex]\frac{8861}{9495}[/tex]
Step-by-step explanation:
Income of an individual in 2001 = [tex]\$ 53,166[/tex]
Income of an individual in 2003 = [tex]\$ 56,970[/tex]
Here, we need to find ratio of income in 2001 to the income in 2003 in simplest form .
i.e we need to convert [tex]\frac{\$53,166}{\$ 56,970}[/tex] in simplest form .
A fraction [tex]\frac{a}{b}[/tex] is said to be in simplest form if [tex]HCF(a,b)=1[/tex]
So, we will first find [tex]HCF(53166,56970)[/tex] then divide both numerator and denominator by the HCF .
Here,
[tex]53166=2\times 3\times 8861[/tex]
[tex]56970=2\times 3\times 3\times 3\times 5\times 211[/tex]
So, [tex]HCF(53166,56970)=2\times 3=6[/tex]
On dividing both numerator and denominator by 6 , we get
[tex]\frac{53166}{56970}=\frac{8861}{9495}[/tex]

Answer:
a.) 1.38 seconds
b.) 17.59ft
Step-by-step explanation:
h(t) = -16t^2 + 22.08t + 6
if we were to graph this, the vertex of the function would be the point, which if we substituted into the function would give us the maximum height.
to find the vertex, since we are dealing with something called "quadratic form" ax^2+bx+c, we can use a formula to find the vertex
-b/2a
b=22.08
a=-16
-22.08/-16, we get 1.38 when the minuses cancel out. since our x is time, it will be 1.38 seconds
now since the vertex is 1.38, we can substitute 1.38 into the function to find the maximum height.
h(1.38)= -16(1.38)^2 + 22.08t + 6 -----> is maximum height.
approximately = 17.59ft -------> calculator used, and rounded to 2 significant figures.
for c the time can be equal to (69+sqrt(8511))/100, as the negative version would be incompatible since we are talking about time. or if you wanted a rounded decimal, approx 1.62 seconds.
Answer:
a) [tex]h(t)=-16(t-0.69)^2)+13.62[/tex]
b)The maximum height is 13.62 feet.
c) 1.84 seconds
Step-by-step explanation:
The function that models the height in feet of the hammer above the ground is
[tex]h(t)=-16t^2+22.08t+6[/tex]
Factor -16 as shown;
[tex]h(t)=-16(t^2-1.38t)+6[/tex]
Add and subtract the square of half the coefficient of t.
[tex]h(t)=-16(t^2-1.38t+(-0.69)^2)--16(-0.69)^2+6[/tex]
[tex]h(t)=-16(t^2-1.38t+(-0.69)^2)--16(-0.69)^2+6[/tex]
Rewrite the first three terms as a perfect square trinomial;
[tex]h(t)=-16(t-0.69)^2)+13.62[/tex]
This function is now in the form;
[tex]h(t)=a(t-h)^2)+k[/tex]
where (h,k)=(0.69,13.62)
This implies that; the hammer reached its maximum height at t=0.69 seconds.
b) The maximum height is the y-value of the vertex.
The maximum height is 13.62 feet.
c) To answer this question we need to find the difference between the x-intercepts.
[tex]h(t)=-16t^2+22.08t+6[/tex]
a=-16,b=22.08,c=6
[tex]t_2-t_1=\sqrt{(t_1+t_2)^2-4t_1t_2}[/tex]
[tex]t_2-t_1=\sqrt{(\frac{-b}{a})^2-4(\frac{c}{a})}[/tex]
[tex]t_2-t_1=\sqrt{(\frac{-22}{-16})^2-4(\frac{-6}{-16}) }=1.84[/tex]
Hence the hammer was in the air for 1.84 seconds

Step-by-step explanation:
The simplified value of the expression [tex]\frac{27^2}{27 ^{4/3}}[/tex] using properties of exponents is 3² or 9.
Given Expression: [tex]\frac{27^2}{27 ^{4/3}}[/tex]
To Simplify the expression, use the following Exponents properties
Quotient Rule: [tex]a^m / a^n = a^{m-n}[/tex] Power Rule: [tex](a^m)^n = a^{(m*n)[/tex]Now, let's factorize the number of prime factors
27 = 3 x 3 x 3 or 3³
So, the Expression [tex]\frac{27^2}{27 ^{4/3}}[/tex] can be written as
[tex]\frac{27^2}{27 ^{4/3}}[/tex] = [tex]\frac{(3^3)^2}{(3^3)^{4/3}}[/tex]
Using Power Rule: [tex](a^m)^n = a^{(m*n)[/tex]
[tex]\frac{27^2}{27 ^{4/3}}[/tex] = [tex]\frac{3^{(3*2)}}{3^{3*(4/3)}}[/tex]
= [tex]\frac{3^6}{3^4}[/tex]
Using Quotient Rule: [tex]a^m / a^n = a^{m-n}[/tex]
[tex]\frac{27^2}{27 ^{4/3}}[/tex] = [tex]\frac{3^6}{3^4}[/tex]
=[tex]3^ {6-4}[/tex]
= 3²
= 9

how much warmer is 82 than -40
Answer: The difference between 82 and -40 is 122.
Step-by-step explanation:
To find out how much warmer 82 degrees is than -40 degrees, you add 40 to 82, which totals 122 degrees.
Explanation:To determine how much warmer 82 degrees is compared to -40 degrees, we simply calculate the difference between the two temperatures. This is a simple calculation where we subtract the lower temperature from the higher temperature.
The calculation would be: 82 - (-40) = 82 + 40 = 122 degrees.
So, 82 degrees is 122 degrees warmer than -40 degrees. Note that this calculation assumes that the temperatures are measured on the same scale, which is typically Fahrenheit in the context of weather temperature changes in the United States.

Final answer:
To find the area of a shape, you multiply its length by its width. Different shapes have different formulas to calculate their areas, such as rectangles and triangles.
Explanation:
In mathematics, to find the area of a shape or region, you need to know the length and width of that shape. For example, to find the area of a rectangle, you multiply its length by its width. The formula for the area of a rectangle is A = length x width.
For example, if a rectangle has a length of 5 units and a width of 3 units, the area would be 5 x 3 = 15 square units.
If you have a shape that is not a rectangle, you may need to use a different formula. For example, to find the area of a triangle, you can use the formula A = 1/2 x base x height. The base is the length of the bottom side of the triangle, and the height is the distance from the base to the top point of the triangle.
what numbers multiply together to make 1120 but add to be -148
Answer:
-140 and -8.
Step-by-step explanation:
-140 x -8 = 1,120.-140 + -8 = -148.These are all of the steps to completely and correctly solve this question.
Hope this helps!!!
Kyle.
Answer:
-8 and -140
Step-by-step explanation:
Let the numbers be x and y. Then xy = 1120, and x + y = -148.
Solving the first equation for y, we get 1120/x.
Substituting this into the second equation: x + 1120/x = -148
Multiplying all terms by x removes x from the denominator(s):
x² + 1120 + 148x = 0.
Let's use the quadratic formula to find x. Here a = 1, b = 148 and c = 1120.
Then the discriminant is b²-4ac, or, in this case, 148²-4(1)(1120) = 17424. Because this discriminant is positive, we have two real, unequal roots.
They are:
-148 ± √17424
x = ------------------------ = -8 and -140.
2
Note that -8 and -140 add up to -148, so that's correct.
(-8)(-140) = 1120, so that also is correct.
