Based on the diagram above, a student determined the hypotenuse of the triangle to be 6√3 Determine if the student's answer is correct. If it is not correct, find the correct length.
Answer:
The student answer is wrong. The correct length of the hypotenuse is 12
Step-by-step explanation:
The question is incomplete without diagram. Find the diagram attached below.
The longest side of the right angled triangle is the hypotenuse.
The side facing the angle 30° is the opposite side of the triangle.
To find the hypotenuse, we will use the SOH CAH TOA method in trigonometry identity.
According to SOH:
Sin30° = Opposite/Hypoenuse
Sin30° = 6/Hypotenuse
Hypotenuse = 6/sin30°
Hypotenuse = 6/0.5
Hypotenuse = 6×2
Hypotenuse = 12
The student answer is wrong. The correct length of the hypotenuse is 12

The point Q lies on the segment PR.
Find the coordinates of Q so that the ratio of PQ to QR is 2:7
P(-22, 32)
R (5, -4)
Answer:
(-16,24)
Step-by-step explanation:
In this problem, we have segment PR, where the endpoins have coordinates
P (-22, 32)
R (5, -4)
We want to find point Q along the segment such that
PQ : QR = 2 : 7 (1)
We can write the coordinates of point Q as
[tex]Q(x_P,y_P)[/tex]
So we can now rewrite eq(1) for both the x- and y- variable:
[tex]\frac{x_Q-x_P}{x_R-x_Q}=\frac{2}{7}[/tex] (2)
[tex]\frac{y_Q-y_P}{y_R-y_Q}=\frac{2}{7}[/tex] (3)
We start by solving eq(2) to find the coordinate x of point Q:
[tex]7(x_Q-x_P) = 2(x_R-x_Q)\\7x_Q-7x_P=2x_R-2x_Q\\9x_Q=2x_R+7x_P\\x_Q=\frac{2x_R+7x_P}{9}=\frac{2(5)+7(-22)}{9}=-16[/tex]
While for the y-coordinate:
[tex]7(y_Q-y_P) = 2(y_R-y_Q)\\7y_Q-7y_P=2y_R-2y_Q\\9y_Q=2y_R+7y_P\\y_Q=\frac{2y_R+7y_P}{9}=\frac{2(-4)+7(32)}{9}=24[/tex]
So the coordinates of Q are (-16,24).
The coordinate of Q is [tex]Q=(-16,4)[/tex]
To understand more, check below explanation.
Section formula:To find the coordinate of Q, we use section formula,
[tex]Q=(\frac{m_{1}x_{2}+m_{2}x_{1}}{m_{1}+m_{2}},\frac{m_{1}y_{2}+m_{2}y_{1}}{m_{1}+m_{2}} )[/tex]
It is given that,
[tex](x_{1},y_{1})=(-22,32),(x_{2},y_{2})=(5,-4), m_{1}=2,m_{2}=7[/tex]
Substitute above values in above section formula,
[tex]Q=(\frac{(2*5)+(7*-22)}{2+7}, \frac{(2*32)+(7*-4)}{2+7})\\\\Q=(-\frac{144}{9} ,\frac{36}{9} )\\\\Q=(-16,4)[/tex]

I need to know what rule represents the enlargement of a figure
Answer:
The correct option is;
(x, y) → (215·x, 215·y)
Step-by-step explanation:
An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.
Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.
Answer:
A. (x, y) → (215x, 215y)
Step-by-step explanation:
Enlargement of a figure is the process of increasing the size of a given figure by the use of a scale. It requires the use of a scale factor that is greater than 1 to form an image. This is called dilation in transformation.
Transformation is the process of manipulating the size or orientation of a figure. To enlarge a shape, a center of enlargement is required.
Thus, the rule that signifies enlargement of a figure is ;
(x, y) → (215x, 215y)
This implies multiplying the initial coordinate x and y by a factor of 215 to produce a required size of an image.

Compute the amount in an account after 8 yr if $6500 is invested at an annual interest rate of 5.25% compounded quarterly. Round to two decimal places.
Answer:
$9865.76¢
Step-by-step explanation:
Please kindly check the attached file for explanation.
Using compound interest, it is found that the amount in the account is of $9,865.76.
Compound interest:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem:
$6500 is invested, thus [tex]P = 6500[/tex]8 years, thus [tex]t = 8[/tex]Interest rate of 5.25%, thus [tex]r = 0.0525[/tex].Compounded quarterly, thus [tex]n = 4[/tex].The amount in the equation is:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(8) = 6500(1 + \frac{0.0525}{4})^{32}[/tex]
[tex]A(8) = 9865.76[/tex]
The amount is of $9,865.76.

Cruz is training to compete in a triathlon. He left his house at 6 : 00 and ran until 7 : 30 . Then he rode his bike until 9 : 45 . He covered a total distance of 51 miles. His speed when biking was 1.6 times his speed when running. Find Cruz's biking and running speeds
Final answer:
Cruz's running speed is 10 mph, and his biking speed is 16 mph, which we found by setting up an equation representing the total distance he covered and the time spent on each activity at their respective speeds.
Explanation:
To determine Cruz's biking and running speeds, we can use the information given about the total distance and the ratio of his speeds. The information tells us that Cruz ran for 1.5 hours (from 6:00 to 7:30) and biked for 2.25 hours (from 7:30 to 9:45). If we let r represent his running speed, then his biking speed would be 1.6r because it's said to be 1.6 times his running speed.
Cruz's total running distance would then be r × 1.5 hours, and his biking distance would be 1.6r × 2.25 hours. We know that the total distance covered is 51 miles, so we can set up the following equation:
1.5r + 1.6r × 2.25 = 51
Now, solve for r:
1.5r + 3.6r = 51
5.1r = 51
r = 51 / 5.1
r = 10 miles per hour
Therefore, Cruz's running speed is 10 mph, and his biking speed is:
1.6 × 10 mph = 16 mph
Cruz's running speed is 10 mph, and his biking speed is 16 mph.

+5)x = 104 represents the situation, where x represents
the width of the rectangle.
(x + 5)x = 104
x2 + 5x - 104 = 0
What are the dimensions of the rectangle?
width=
inches
length =
inches
5) Intro
Answer: x=8
Width=8 inches
Length=13 inches
Final answer:
The width of the rectangle is 8 inches and the length is 13 inches, as determined by solving the quadratic equation representing the area of the rectangle.
Explanation:
To solve for the dimensions of the rectangle, we need to find the value of x, which represents the width of the rectangle. The quadratic equation we have is x² + 5x - 104 = 0.
Factoring this equation, we are looking for two numbers that multiply to -104 and add to 5.
These numbers are 13 and -8, so the equation factors to (x + 13)(x - 8) = 0. Setting each factor equal to zero gives us two possible solutions for x: x = -13 or x = 8.
Since a width cannot be negative, the only sensible solution for this problem is x = 8 inches. Given that the length is 5 inches more than the width, the length will be 8 inches + 5 inches = 13 inches.
Dimensions of the rectangle:
Width = 8 inches
Length = 13 inches

Given g(x) = -x – 4, solve for x when g(x) = 9.
To solve for x when g(x) = 9 given the function g(x) = -x – 4, set the equations equal to each other. Rearrange the equation and solve for x, which gives x = -13
Explanation:The question asked for the value of x when g(x) = 9 given the function g(x) = -x – 4. We can start by setting the two equations equal to each other. This gives us -x - 4 = 9. Next, we rearrange the equation to solve for x by adding 4 to each side, which gives us -x = 9 + 4 or -x = 13. To get x on its own, we divide each side by -1. This gives us x = -13. Therefore, when g(x) = 9, x is equal to -13.

Answer: AB=5.66, AC=4
Step-by-step explanation:
So this triangle is a 45-45-90 triangle, meaning it has one 90 degree angle and two 45 degree angles.
If you remember from geometry, the sides that have the same angle have the same length, and seeing as angle A is 45 degrees and side BC is 4, we can know for certain that angle B is 45 degrees and side AC is also 4.
This is because angle C is already marked as the 90 degree angle due to the square symbol in it.
Now to find side AB, we would use our friend the Pythagorean Theorem, which states that [tex]a^2+b^2=c^2[/tex].
Let a = side BC and b = side AC, meaning c = side AB.
Now plug in the values and solve:
[tex]4^2+4^2=c^2[/tex]
[tex]32=c^2[/tex]
[tex]\sqrt{32} =\sqrt{c^2}[/tex]
