Answer: x = 65.63
Explanation:
We have, 64% × x = 42 or, 64/100 × x = 42
Multiplying both sides by 100 and dividing both sides by 64, we have x = 42 × 100 64
x = 65.63

Using the provided measures determine the measure of angle K.

forsale [732]

Answer:

B. 34.90°

Step-by-step explanation:

✔️First, find GF using Trigonometric function:

Reference angle = 58°

Adjacent length = GF

Hypotenuse = 6 cm

Apply CAH, thus:

Cos 58 = Adj/Hyp

Cos 58 = GF/6

GF = 6*Cos 58

GF = 3.17951558 ≈ 3.18 cm

✔️Find angle K using the Sine Rule:

$\frac{sin(K)}{GF} = \frac{sin(G)}{KF}$

Substitute

$\frac{sin(K)}{3.18} = \frac{sin(64)}{5}$

Multiply both sides by 3.18

$sin(K) = \frac{sin(64)}{5}*3.18$

$sin(K) = 0.5716$

$K = sin^{-1}(0.5716)$

K = 34.8618741° ≈ 34.90°

Which two equations represent a nonlinear function?

irina [24]

Answer: See below.

Step-by-step explanation:

The formatting is likely incorrect for these two options:

y=(x−1)2, and

y = ( x − − 1 ) 2

I'll assume they were meant to be:

y=(x−1)^2, and

y = ( x + 1 )^2

In this case they would be non-linear, since y depends on the value of $x^{2}$

Use a "^" sign to indicate raised to a power: x^2 means $x^{2}$ .

y=(x−1)2 means y = 2x - 2

y=(x−1)^2 means y = $(x-1)^{2}$
