To solve this you must use Pythagorean theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 5
b = 8
c = x
^^^Plug these numbers into the theorem
[tex]5^{2} +8^{2} =x^{2}[/tex]
simplify
25 + 64 = [tex]x^{2}[/tex]
89 = [tex]x^{2}[/tex]
To remove the square from x take the square root of both sides to get you...

Answer:
The correct answer is first option √89
Step-by-step explanation:
Points to remember
Pythagorean theorem
For a right triangle,
Base² + Height² = Hypotenuse²
To find the vale of x
From the figure we can see a right triangle,
Base = 8 units and height = 5 units
Hypotenuse² = Base² + Height²
x² = 8² + 5²
= 64 + 25
= 89
x = √89
The correct answer is first option √89

The measure of A is 10° greater than the measure of B. The two angles are complementary. Find the measure of each angle.
The m A is ° and m B is °.
since its complementary, the sum if both angles equals 90 degrees.
you do x+x+10 so you combine like terms to get 2x+10=90
then you subtract 10 to get
2x=80
and divide by 2
x=40
angle a=50 degrees
angle b=40 degrees
Answer:
m < A = 50 degrees, m < B = 40 degrees.
Step-by-step explanation:
Complementary angles sum to 90 degrees, so:
A + B = 90
As A = B + 10:
B + 10 + B = 90
2B = 80
B = 40.
So A = 40 + 10 = 50.

what is the vertex form of f(x) = x2 + 6x + 3
Answer: [tex]y=(x +3)^2 -6[/tex]
Step-by-step explanation:
The equation of a parabola in Vertex form is:
[tex]y=a(x-h)^2+k[/tex]
Where [tex](h,k)[/tex] is the vertex of the parabola
We can rewrite the function [tex]f(x)= x^2 + 6x + 3[/tex] as:
[tex]y= x^2 + 6x + 3[/tex]
In order to convert it into vertex form we need to Complete the square:
Take the coefficient of the x term, divide it by 2 and square it:
[tex](\frac{6}{2})=3^2[/tex]
Add and subtract 3² on the right side:
[tex]y= x^2 + 6x+3^2 + 3-3^2[/tex]
Now we must convert the right side to a squared expression, then we get:
[tex]y=(x +3)^2 -6[/tex]

What is the converse of the following true conditional? If the converse is true, rewrite the statements as a biconditional. If either is false, give a counterexample.
If two lines are parallel, they do not intersect.
Select one:
a. If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.
b. If two lines do not intersect, they are parallel. One statement is false. If two lines are parallel, they may intersect twice.
c. If two lines do not intersect, they are parallel. Both statements are true. Two lines are parallel if (and only if) they do not intersect.
d. If two lines do not intersect, they are not parallel. Both statements are true. Two lines are not parallel if (and only if) they do not intersect.
Answer: A
Step-by-step explanation: The converse of a conditional is when the two statements switch spots, for example:
Conditional: If someone like ice cream, they have brown hair
Converse: If someone has brown hair, they like ice cream
The converse of our given conditional would be:
If two lines do not intersect, they are parallel
This eliminates Option D
Next, the converse is false.
Skew lines (example attached) do not intersect and are also not parallel, meaning if two lines do not intersect, they could be either parallel or skew.
This eliminates Option C and B, leaving us with Option A
We want to find the converse statement to one given statement and see if it is true.
We will see that the correct option is a:
If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.
A general statement is written as:
If P then Q.
Where P and Q are two given propositions.
The converse statement to the above shown is:
If Q then P.
For this question, we have the statement:
If two line are parallel, they do not intersect.
Then we can write the converse statement as:
If two lines do not intersect, they are parallel.
Which is false, in 3-dimensions we can have two non-parallel lines that don't intersect each other (parallel lines must not intersect and also live on the same plane).
Then the correct option is the first one:
a: If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.

Evaluate B2 for B = 9.
B^2 for B = 9 means squaring the value of 9, resulting in 9^2, which equals 81. Therefore, B^2 for B = 9 is 81.
To evaluate B^2 for B = 9, you simply substitute the value of B into the expression and then perform the calculation. Here's how it's done:
B^2 means "B squared," which is equivalent to multiplying B by itself. So, for B = 9, we have:
[tex]\(B^2 = 9^2 = 9 \times 9\)[/tex]
Now, calculate the product:
[tex]\(9 \times 9 = 81\)[/tex]
So, B^2 for B = 9 is equal to 81.
In summary, when you substitute B = 9 into the expression B^2, you get 9^2, which equals 81. Therefore, B^2 for B = 9 is 81.

You are measuring the height of a statue. You stand 10 feet from the base of the statue. You measure the angle of elevation from the ground to the top of the statue to be 76 degrees find the height h of the statue to the nearest foot
Answer:
h = (10 ft)(4.01) = 40.1 ft
Step-by-step explanation:
The tangent function relates this elevation to the horizontal distance (10 ft) and the angle of elevation (76 degrees):
opp h
tan 76 degrees = --------- = ------------- = 4.01
adj 10 ft
Therefore , h = (10 ft)(4.01) = 40.1 ft
Answer: 40 ft
Step-by-step explanation:
You can find the height of the statue by solving the right triangle.
In this case the adjacent side of the triangle is the horizontal distance to the statue (10 ft). The height of the statue is the opposite side to the angle of 76 °.
By definition, the tangent of an angle is:
[tex]tan(\theta) = \frac{opposite}{adjacent}[/tex]
In this case
[tex]\theta=76\°\\\\opposite = h\\\\adjacent = 10\ ft[/tex]
Therefore
[tex]tan(76) = \frac{h}{10}[/tex]
[tex]h=tan(76) * 10\\\\h=40\ ft[/tex]
The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
Answer:
89.95 + 4x =628.35
x = 134.60
Step-by-step explanation:
The trip to the dentist had a flat fee plus 4 cavities for a total cost of 628.35
fee + 4 * cost of cavity = 628.35
Let x = the cost of each cavity
89.95 + 4x =628.35
Subtract 89.95 from each side
89.95-89.95 + 4x =628.35-89.95
4x =538.40
Divide each side by 4
4x/4 =538.40/4
x =134.60

Find three consecutive numbers such that the sum of one-fourth the first and one-fifth the second is five less than one-seventh the third
Answer:
The numbers are -16,-15 and -14
Step-by-step explanation:
Let
x ----> the first number
x+1 ----> the second number
x+2 ---> the third number
we know that
(1/4)x+(1/5)(x+1)=(1/7)(x+2)-5
Multiply by (4*5*7) both sides
35x+28(x+1)=20(x+2)-140*5
35x+28x+28=20x+40-700

The number of potato chips in a bag is normally distributed with a mean of 75 and a standard deviantion of 5. Approximately what percent of bags contain between 65 and 85 potato chips?
a. 68%
b. 75%
c. 95%
d. 99.7%
The percentage of bags contain between 65 and 85 potato chips is 95%.
Step-by-step explanation:
A probability distribution that is symmetric and the data near the mean are more frequent than far is known as a normal distribution. Normal distributions are important in statistics and are often used to represent real-valued random variables.
The formula for finding the percentage of bags using normally distributed is given as
f(x) = (1 / sigma * square root 2 *pi) * e^((-1/2)*((x-u)/sigma))
Substituting the values of mean and standard deviation,
The percentage of bags contain between 65 and 85 potato chips is 95%.
Final answer:
Using the empirical rule, approximately 95% of potato chip bags will contain between 65 and 85 chips, as this range spans two standard deviations away from the mean in a normal distribution.
Explanation:
The question is regarding the percentage of potato chip bags that contain a specific number of chips based on a normal distribution. With a mean of 75 and a standard deviation of 5, the range of chips in the bags is between 65 and 85. To find this percentage, we use the empirical rule, sometimes referred to as the 68-95-99.7 rule, which states that approximately 68% of the data within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Since the range from 65 to 85 chips spans two standard deviations from the mean (65 is 10 chips away from 75 which is two standard deviations as 5*2=10, and the same logic applies for 85), we can say that approximately 95% of the bags will contain between 65 and 85 potato chips.

C.f() = 1/2 x2 + 6x -16
D f() = -x2 + 12x -6
Answer:
Option B [tex]f(x)=-x^{2}+12x-32[/tex]
Step-by-step explanation:
we know that
For the given values, the quadratic function is a vertical parabola open downward (vertex is a maximum)
The equation in vertex form is equal to
[tex]f(x)=a(x-h)^{2} +k[/tex]
where
(h,k) is the vertex
a is a coefficient
we have
(h,k)=(6,4)
so
[tex]f(x)=a(x-6)^{2} +4[/tex]
Find the value of a
For x=8, y=0 -----> the y-intercept
substitute
[tex]0=a(8-6)^{2} +4[/tex]
[tex]0=a(2)^{2} +4[/tex]
[tex]0=4a +4[/tex]
[tex]a=-1[/tex]
substitute
[tex]f(x)=-(x-6)^{2} +4[/tex]
Convert to standard form
[tex]f(x)=-(x^{2}-12x+36) +4[/tex]
[tex]f(x)=-x^{2}+12x-36+4[/tex]
[tex]f(x)=-x^{2}+12x-32[/tex]
