Find the length of the third side. If necessary, write in simplest radical form.
Answer:
[tex]\boxed {\boxed {\sf 8}}[/tex]
Step-by-step explanation:
This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs of the triangle and c is the hypotenuse.
In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:
[tex]a= 7 \\b= \sqrt{15}[/tex]
Substitute these values into the formula.
[tex](7)^2+(\sqrt{15})^2=c^2[/tex]
Solve the exponents.
(7)²= 7*7=49[tex]49+ (\sqrt{15})^2=c^2[/tex]
(√15)²=√15*√15=15[tex]49+15=c^2[/tex]
Add.
[tex]64=c^2[/tex]
Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.
[tex]\sqrt{64}=\sqrt{c^2} \\\sqrt{64}= c\\8=c[/tex]
The third side length is 8.

Question 2 of 37
Suppose that F(x) =3/x and G(X) 3/x-10Which statement best compares
the graphs of F(x) and G(x)?
Answer:
F(x) = x^3 and G(x) = (4x)^3 − 5
so
G(x) = F(4x) -5
the visual effect is
1) shrink horizontally by 1/4
2) shift down by 5
therefore
the answer is the option
D.The graph of G(x) is the graph of F(x) compressed horizontally and shifted 5 units down.

Answer:
radius = 5 cm
height = 10 cm
Volume = 261.8 cm³
Step-by-step explanation:
Radius (r) = 5 cm
Height (h) = 10 cm
Volume of the cone (V) = ⅓πr²h
Plug in the values
V = ⅓*π*5²*10
V = ⅓*π*25*10
V = 261.8 cm³ (nearest tenth)

explain how the diagram can help find the area of a circle
Answer:
Step-by-step explanation:
This is a really famous diagram! The circle has been divided into many wedges (think slices of pizza!). The wedges have been colored alternately blue and yellow, then the wedges were rearranged to form a "rectangle" -- well, it's approximately a rectangle because the wedges have arcs (pieces of a circle) on them. See how the bottom and top edges of the rectangle look bumpy?
The area of the "rectangle" is approximately [tex]\pi r^2[/tex] . The reason is that the height of the rectangle is r , the radius of the circle. And the length of the rectangle is about [tex]\pi r[/tex] -- half the circumference of the circle. It's half because the circumference is in the bumpy parts of the wedges--half blue, half yellow.
The approximation improves as the number of wedges increases. In fact, as the number of slices (sorry, pizza again) gets larger, the length of the rectangle gets closer and closer to half the circumference. In other words, making more wedges makes the rectangle less bumpy!
What is the slope of the line that passes through the points (3, 2) and (−1,2)? Write your answer in the simplest form
Answer:
slope = 0
Step-by-step explanation:
To find the slope of a line that passes between a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the points (3,2) and (-1,2) into the formula and simplify:
[tex]m = \frac{(2)-(2)}{(-1)-(3)} \\m = \frac{2-2}{1-3} \\m = \frac{0}{-2} \\m=0[/tex]
So, the slope is 0.

A large bakery makes cakes in two shifts: shift A and shift B. Suppose that, on average, cakes from shift A weigh
7.4 kg with a standard deviation of 0.2 kg. For shift B, the mean and standard deviation are 7.0 kg and 0.1 kg,
respectively.
Every day, the bakery takes an SRS of 25 cakes from each shift. They calculate the mean weight for each sample,
then look at the difference (A - B) between the sample means.

To keep producing a specific shirt style, a clothing company must make a profit of at least $5,000 on the style.
This system of inequalities models the potential profit from the sales of the shirt style and the profit constraints, where p represents the profit
and x is the shirt price,

Answer:
At x = 15 ; price meets profit goal
At x = 25 ; price does not meet profit goal
Step-by-step explanation:
Constraint:
p < -15x2 + 600x + 60
P ≥ 5,000
x = shirt price ;
If x = 15
p ≤ -15(15²) + 600(15) + 60
p ≤ -3375 + 9000 + 60
p ≤ 5685
p ≥ 5000
5685 ≥ 5000 ( condition is met)
2.)
With a shirt price of $25
x = 25
p ≤ -25(25²) + 600(25) + 60
p ≤ -15625 + 15000 + 60
p ≤ - 565
p ≥ 5000
-565 < 5000 ( condition is not met)
a) When the price of the shirt is $15, the company meets its profit goals.
b) When the price of the shirt is $25, the company meets its profit goals.
What is the profit goal?The profit goal is met when the price of a good or service exceeds the costs of its production and sales.
At p < -15(15)^2 + 600 (15) + 60 and p <= -15(25)^2 + 600(25) + 60, the profit goal of $5,000 is met.
Thus, we can conclude that:
a) When the price of the shirt is $15, the company meets its profit goals.
b) When the price of the shirt is $25, the company meets its profit goals.

in size between Kim's farm and
Jack's farm?

C100 acres
D90 acres
Answer:
d 90
Step-by-step explanation:
hope this helped you
Answer:
B. 200 acres
Step-by-step explanation:
Create an estimate by rounding the size of each of their farms to the nearest hundred.
Kim's farm is approximately 1,300 acres, since 292 is closest to 300.
Jack's farm is approximately 1,100 acres, since 104 is closest to 100.
Using these estimates, find the difference between them:
1,300 - 1,100
= 200
So, the best estimate of the size difference is B. 200 acres
