I need help with this question it’s about circle angle things it’s for my practice test

Scale factor = (image)/(preimage)

[tex]AC=8\\\\A'C'=12[/tex]

So, the scale factor is [tex]\frac{12}{8}=\boxed{1.5}[/tex]

Answer:

[tex](a)\ f(x) =200(1.25)^x[/tex]

(b) 954 birds after 7 years

Step-by-step explanation:

Given

[tex]a = 200[/tex] --- initial

[tex]r =25\%[/tex] --- rate

Solving (a): The function.

This is represented as:

[tex]f(x) =a(1+r)^x[/tex]

So, we have:

[tex]f(x) =200(1+25\%)^x[/tex]

Express percentage as decimal

[tex]f(x) =200(1+0.25)^x[/tex]

[tex]f(x) =200(1.25)^x[/tex]

Solving (b): Birds after 7 years

This implies that we calculate f(7)

[tex]f(7) =200(1.25)^7[/tex]

[tex]f(7) =953.67[/tex]

[tex]f(7) =954[/tex] --- approximated

Answer:

(3, -5).

Step-by-step explanation:

By the definition of inverses:

[tex]\text{If $f(a) = b$, then $f^{-1}(b)=a$}[/tex]

In other words, the inverse of a function returns the input when given the output of the original function.

We know that the point (-5, 3) lies on the graph of f(x). In other words:

[tex]f(-5)=3[/tex]

Then by definition:

[tex]f^{-1}(3)=-5[/tex]

So, the point (3, -5) must lie on the graph of f⁻¹(x).

Answer:

C 230, 92, 75, -52, -92

Step-by-step explanation:

from greatest to least.

please tell your teacher it would correctly be called "from highest to lowest".

but he/she was only focusing on numbers. understandably. so, from the greatest value to the least value.

positive numbers get smaller in their absolute values, when we go to the smaller side, but negative numbers get "bigger" in their absolute values, when we go to the smaller side.

-2 is smaller or lower than -1

and so on.

that is the reason for the correct answer.

Answer:

Step-by-step explanation:

The top part (is a square)

Area = s^2

Area = 10 * 10

Area =                                     100

The bottom part is a trapezoid

h = 4

b1= 6

b2 = 10

Area = (b1 + b2) * h / 2

Area = (10 + 6 ) * 4/2

Area = 16 * 4 /2

Area =                                     32

Total Area =                           132

Answer:

y = -7

Step-by-step explanation:

This is a horizontal line

The y value does not change

It is of the form y=

y = -7

Answer:

y = -7

Step-by-step explanation:

A horizontal line has an equation of the form

y = k

where k is the y-coordinate of every point on the line.

We see that every point on this line has y-coordinate -7, so the equation is

y = -7

Answer:

1.5 pounds of oranges cost $0.81 more than 1.5 pounds of apples

Step-by-step explanation:

1.5 pounds of apples = 1.5 × $1.30 = $1.95

1.5 pounds oforanges = 1.5 × $1.84 = $2.76

$2.76 - $1.95 = $0.81

x/32 = 18/13

Answer:14 dollars, 2 pounds

Step-by-step explanation:

for they first one your just rounding wich is kinda easy you just round it up to the nearest dollar wich is 1 plus 13= 14 dollars.

for the second one it would be better to specify, but since we already did rounding on the first one this might be about the same topic, meaning it might be 2 pounds. But if not 2 and 1/4 of a pound.

Answer: the answer is in simple rounding-terms, 13.55 dollars rounded to dollars is just rounding off the cents, specifically the dimes or quarters. 55 cent can also be a half-dollar, but that is not important, 0.5 can be rounded to 1 in this case, so for question 14 you would add one to 13 dollars since 0.50 cents got rounded to 1 dollar and you get 14 dollars as your answer for the first question. for the next question American cheese i would assume is the same as the cheese referenced by Mr. Marsh, so the answer  would be 2.25 pounds of cheese for number 15

Step-by-step explanation: my answer.

the answer is 14, 2.25

Answer:

Step-by-step explanation:

The formula for finding area is [tex]\pi[/tex]r2, and since half of diameter is radius, we'll need to divide the diameters given by 2. So the formula will be A = π (d/2)2.

Answer:

13π

Step-by-step explanation:

A(Circle) = πr²

r = d/2

A(Large) = π(7)² = 49π

A(Medium) = π(6)² = 36π

Therefore, the area of a large pizza is 13π greater than the area of a medium pizza.

Check arithmetic

t4-t3 t3-t2

25-16 16-9

=9 =7

sequence is not arithmetic bcoz t4-t3 is unequal to t4-t3

check geometric

t4÷t3 t3÷t2

25÷16 16÷9

=1.6 1.7

sequence is not geometric bcoz t4÷t3 is unequal to t3÷t2

neither

Answer:

y = 0.36

Step-by-step explanation:

Given y is inversely proportional to x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation

To find k use the condition y = 9 when x = 2 , then

9 = [tex]\frac{k}{2^2}[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

36 = k

y = [tex]\frac{36}{x^2}[/tex] ← equation of variation

When x = 10 , then

y = [tex]\frac{36}{10^2}[/tex] = [tex]\frac{36}{100}[/tex] = 0.36

Step-by-step explanation:

ASA congruent triangles shall have one more angle being equal

Answer:

(x, y) = (-1, 4)

Step-by-step explanation:

3x + 3y = -3 (1)

-2x + y = 2 (2)

From (2)

y = 2 + 2x

Substitute y = 2 + 2x into (1)

3x + 3y = -3 (1)

3x + 3(2 + 2x) = -3

3x + 6 + 6x = -3

9x + 6 = -3

9x = -3 - 6

9x = -9

x = -9/9

x = -1

Substitute x = -1 into (2)

-2x + y = 2 (2)

-2(-1) + y = 2

-2 + y = 2

y = 2 + 2

y = 4

(x, y) = (-1, 4)

Answer:

$115/hr    The 10 hr mechanic

$50/hr    The 5hr mechanic

Step-by-step explanation:

let the 10 hr mechanic charge x

then the 5 hr mechanic charges 165 - x

------------------------------

10x + 5(165 - x) = 1400

10x + 825 - 5x = 1400

5x = 575

x = 115    The 10 hr mechanic

165 - x = 50    The 5hr mechanic
