Answer:

AC= 20

Step-by-step explanation:

since the two figures are similar, CB Is congruent to FD

since image/preimage, 12/3 =4

The dilation is 4.

AC is congruent to EF

EF=5

4 x 5 = 20

AC=20

someone correct me if im wrong :)

Algebra help - asymptotes

motikmotik

Find where the equation is undefined ( when the denominator is equal to 0.

Since they say x = 5, replace x in the equation see which ones equal o:

5-5 = 0

So we know the denominator has to be (x-5), this now narrows it down to the first two answers.

To find the horizontal asymptote, we need to look at an equation for a rational function: R(x) = ax^n / bx^m, where n is the degree of the numerator and m is the degree of the denominator.

In the equations given neither the numerator or denominators have an exponent ( neither are raised to a power)

so the degrees would be equal.

Since they are equal the horizontal asymptote is the y-intercept, which is given as -2.

This makes the first choice the correct answer.

1) 14 units2 2) 16 units2 3) 17 units2 4) 19 units2

horrorfan [7]

Answer:

<h2>4th option: 19 units2 </h2>

Step-by-step explanation:

<h3>The given figure can be divided as (i) upper rectangle, (ii) lower rectangle </h3>

Then,

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

Therefore, 

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

Therefore, 

Area of the lower rectangle = 5 × 1 = 5 units2

Since,

Area of the figure is = Area of upper rectangle + Area of lower rectangle 

= 14 units2 + 5 units2

= 19 units2 (Ans) (4th option)

Suppose line AT bisects ∠CAR. if ∠CAT = 5x and ∠CAR = 9x +7, what is ∠TAR

zepelin [54]

Answer:

∠TAR = 35°

Step-by-step explanation:

∠TAR = ∠CAR - ∠CAT = (9x + 7) - 5x = 4x + 7

AT bisect ∠CAR ∠TAR = ∠CAT

4x + 7 = 5x

x = 7

∠TAR = 4 x 7 + 7 = 35
