Answer:

y=-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-(-4))/(-6-4)=(-4+4)/-10=0/-10=0

slope is 0

y-y1=m(x-x1) where m=slope

y-(-4)=0(x-4)

y+4=0

y=0-4=-4

y=-4

Answer:

Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees

Step-by-step explanation:

Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:

[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]

And we use the sin function to deal with angle <D:

[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]

my answer is that 6.28 will be the answer.

Answer:

64

Step-by-step explanation:

We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.

Since we know that x equals 2. We can substitute 2 for every x in the expression.

7(2)^2 + 8(2) + 20

First do the exponent :

2^2

4

7(4) + 8(2) + 20

Multiply 7(4) and 8(2) :

7(4)

28

8(2)

Answer:

Sales Tax $2.55

Final Cost $36.55

Step-by-step explanation:

Finding sales tax

34 * 7.5%= 2.55

Multiply the tax with the original cost, that will be your sales tax

Finding final cost

34 + 2.55= 36.55

Add your sales tax with the original cost, now you have the final total

Answer:

x = 60

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

[tex]\frac{1}{6}[/tex](x+6)=11

[tex]\frac{1}{6}[/tex]x + 1 = 11

[tex]\frac{1}{6}[/tex]x +1 -1 = 11 -1

[tex]\frac{1}{6}[/tex]x * 6 = 10 *6

x = 60

To double check

[tex]\frac{1}{6}[/tex](60+6)=11

10+1 = 11

11 = 11

Answer:

4.46cm

Step-by-step explanation:

Volume of a frustum is expressed as;

V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))

h is the height of the frustum

r₁ and r₂ are the radii of its ends

V is the volume

Given

V = 9100cm₃

r₁ = 10cm

r₂ = 30cm

Substitute

9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))

9100 = 1/2(3.14)*h*(100+900+300)

9100 = 1.57*h*(1300)

9100 = 2,041h

h = 9100/2,041

h = 4.46cm

Hence the height of the cap is 4.46cm

Answer:

$24.75

Step-by-step explanation:

4/5 of 13.75 = 11

11+13.75= 24.75

Dana  spends $24.75 in all.

An equation is a mathematical statement that equates two algebraic expression by an equal sign.

The data given in the question is

Dana spends $13.75 on a teacup for her grandmother

She spends 4/5 of that on a coffee mug for her grandfather.

The total amount  she spends is given by $x

The equation becomes

x = 13.75 + (4/5) * 13.75

x = $24.75

Therefore she spends $24.75 in all.

Answer:

26. H. (-4, -2)

27. A. x - 4

Step-by-step explanation:

26.

Use translations.

Start at point A(2, 6). To go from this point to the center of the circle, you must go from A(2, 6) to C(-1, 2). That means you need to go from 2 to -1 in x, a change of -3 in x, and from 6 to 2 in y, a change of -4 in y.

Since points A and B are the endpoints of a diameter, then AC and BC are radii of the circle. All radii are congruent, so if you apply the same transformation as from A to C to point C, you will get the coordinates of point B.

C(-1, 2) now is transformed by -3 in x and -4 in y.

B(-1 - 3, 2 - 4) ----> B(-4 , -2)

Answer: H. (-4, -2)

Recall the factoring of a difference of cubes.

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

You have

x^3 - 64

x^3 is obviously the cube of x.

64 is the cube of 4, so you have

x^3 - 4^3

Following the factorization above, you get

(x - 4)(x^2 + 4x + 16)

Answer: A. x - 4
