Evaluate 5k + 1 when: *

wlad13 [49]

k^2 = 4k

k = 0, k = 4

k^2 - 5k = k + 7

k^2 - 6k = 7

k^2 - 6k + 9 = 16

k - 3 = 4 ⇒ k = 7

k - 3 = -4 ⇒ k = -1

k^3 - 5k^2 + 3k = -k

k^3 - 5k^2 + 4k = 0

k(k^2 - 5k + 4) = 0

k = 0, k = 1, k = 4

|k + 1| + 2 = 8

|k + 1| = 6

k = 5, k = -7

Eight years ago, Clyde was 7 years old. Which equation represents Clyde age now?

vichka [17]

Answer:

Step-by-step explanation:

Clyde's present age is 7+8, because he has aged 8 years since he was 7.

So, the equation would be C=7+8.

However, that equation isn't listed so you need to move some numbers around.

If you subtract 8 from both sides of the equation C=7+8, you get C-8=7, which is D.

Hope this helps! :)

you are given a fraction in simplest form. the numerator is not zero.when you write the fraction as a decimal,it is a repeating

PolarNik [594]

Answer:

3, 6, 7, 9

Step-by-step explanation:

We can take a look at each value from 1 to 10

We see that for 3, 6, 7, and 9 the decimal repeats forever for some numerators. For example, 1/3 repeats forever, 4/6 repeats forever, 5/7 repeats forever, 1/9 repeats forever.

A communications tower is supported by two wires, connected at the same point on the ground. One is attached to the tower at D a

viktelen [127]

Answer:

10.99 m

Step-by-step explanation:

✍️What we are basically asked to solve here is to find the distance between C and D.

To find CD, find the length of BC, and BD. Their difference will give us CD.

Thus, BC - BD = CD.

✍️Finding BC using trigonometric ratio formula:

$\theta = 30 + 10 = 40$

Opposite side = BC = ??

Adjacent side = 42 m

Thus:

$tan(\theta) = \frac{opposite}{adjacent}$

Plug in the values

$tan(40) = \frac{BC}{42}$

Multiply both sides by 42

$tan(40) \times 42 = \frac{BC}{42} \times 42$

$35.24 = BC$

BC = 35.24 m

✍️Finding BD using trigonometric ratio formula:

$\theta = 30$

Opposite side = BD = ??

Adjacent side = 42 m

Thus:

$tan(\theta) = \frac{opposite}{adjacent}$

Plug in the values

$tan(30) = \frac{BD}{42}$

Multiply both sides by 42

$tan(30) \times 42 = \frac{BD}{42} \times 42$

$24.25 = BD$

BD = 24.25 m

✍️How much below the top of the tower is the shorter one attached:

Thus,

BC - BD = CD

35.24 m - 24.25 m = 10.99 m
