Answer:

{0, 1, 16, 81}

Step-by-step explanation:

If the domain of this function is the set {0, 1, 4, 9}, we find the set representing the range by evaluating the function at each of the four values in the domain.

f(0) = 0

f(1) = 1

f(4) = 16

f(9) = 81

and so the range is the set {0, 1, 16, 81}.

Answer:

(4th option) 254.34 cm

Step-by-step explanation:

Area of a circle = pi (r)^2

r=radius of circle which is half of diameter.

diameter=12+6=18

So, radius is half of 18 = 9

Plug it into the formula:

[tex]\pi (9)^{2}[/tex]

And you should get 254.34 cm^2

Answer:

Step-by-step explanation:

area of a circle is pi * r^2

r for the big circle is 1/2 of 18 or 9

pi * 9^2 = 254.469

Answer:

1. 130°

2. corresponding

3. congruent

Step-by-step explanation:

Answer:

In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. ... The word "tangent" comes from the Latin tangere, "to touch".

Step-by-step explanation:

A straight line touching a curve at a single point without crossing it there is tangent.

Answer:

Hanno moves faster than Simone.

Step-by-step explanation:

Simone: 25x100=2500m or 2.5km in 25x12=300 seconds or 5 minutes

Hanno- 2.5 km in 4minutes

So, Hanno moves 1 minute faster.

Answer:

FGJ +JGH=90

25+x. =90

x. =90-25

x. =65°

Answer:

65

Step-by-step explanation:

Hey There!

Those are a pair of complementary angles meaning that they will add up to equal 90

so to find x we subtract the given angle from 90

90-25=65

therefore x=65

Answer:

781250

Step-by-step explanation:

We first need to find the common ratio

-10 /2 = -5

50 / -10 = -5

The common ratio is -5

an = a (r) ^ (n-1)

a9 = 2 ( -5) ^(9-1)

     = 2 (-5)^8

      =781250

Answer:

82° ; 50° ; 52° ;domain error ;51° ; domain error

Step-by-step explanation:

Using a calculator :

sin(A) = 0.9903

A = sin^-1(0.9903) = 82.01 = 82°

6.) cos(A) = 0.6428

A = cos^-1(0.6428) = 49.99 = 50°

8.) tan(A) = 1.2851

A = tan^-1(1.2851) = 52.111 = 52°

9.) cos(A) = 1.2608

A = cos^-1(1.2608) = domain error

10.) sin(A) = 0.7777

A = sin^-1(0.777) = 50.98 = 51°

11.) sin(A) = 1.8330

A = sin^-1(1.8330) = domain error

Answer:

Use the slope-intercept form y=mx+b to find the slope m. m=−1

Step-by-step explanation:

lets take the x's away from: -5x+4x

That will be -5+4

-5+4=-1

Because remember:

When adding positive numbers, count to the right.

When adding negative numbers, count to the left.

When subtracting positive numbers, count to the left.

When subtracting negative numbers, count to the right.

I hope this helps.       :)

Answer:

Answer:

45.7

Step-by-step explanation:

Hello there!

We can calculate the missing angle using trigonometry

here are the trigonometric ratios

sin = opposite over hypotenuse

cos = adjacent over hypotenuse

tan = opposite over adjacent

We are given x's opposite side length (8) and x's adjacent side length (7.8)

we are given the information to use the trigonometric ratio tangent

so now we create an equation (remember tan - opposite over tangent)

[tex]tan(x)=\frac{8}{7.8}[/tex]

now we solve for x

[tex]\frac{8}{7} =1.025641026[/tex]

we're left with

[tex]tan(x) =1.025641026[/tex]

finally we want to get rid of the tan

To do so we take the inverse of tan (arctan^-1) and apply it to each side

[tex]arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243[/tex]

so x = 45.7252243

finally we round to the nearest tenth and get that the answer is

45.7

Answer:

x= 11.4

Step-by-step explanation:

for the base of the triangles BC is 15 and DF is 5 so if 5 times 3 is 15 then you are reducing the other triangle to a third of the big triangles size. so 3.8 times three is 11 4

Answer:

w ≥ 1

Answer:

(9.2 , 0)

Step-by-step explanation:

vertex: (4.6 , 12.2)

parabola: y = a (x-4.6)² + 12.2

pass (0,0):  0 = a (0-4.6)² + 12.2

a = - (12.2/21.16)

2nd root (x , 0):  y=0

0 = a (x-4.6)² + 12.2           (x-4.6)² = - 12.2 / a = -12.2 / (- (12.2/21.16)) = 21.16

x - 4.6 = ± √21.16 = ± 4.6

x = 0 or x = 9.2
