Answer:

12/3 or 4

Step-by-step explanation:

When solving for a constant use the equation y/x. All you need to do is find the y coordinate and the x coordinate and divide the 2.

Plugin 12 for y and 3 for x

\\ \sf\longmapsto \sqrt{-(10)^2}

\\ \sf\longmapsto \sqrt{10^2}\sqrt{-1}

\\ \sf\longmapsto 10i

Write in standard form

\\ \sf\longmapsto 10i

\\ \sf\longmapsto \boxed{0}+\boxed{10}i

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°

Find (3.3 × 10^4) + (1.9 × 10^5)
scoundrel [369]

Answer:

2.23 \times 10^{5}

Step-by-step explanation:

We have to find the sum of two numbers following the steps as described in the question.

The question is in the form of fill in the blanks.

Now, the given sum is (3.3 \times 10^{4} )+(1.9 \times 10^{5} )

= (3.3 \times 10^{4} )+(19 \times 10^{4} )

= (3.3+19) \times 10^{4}

= 22.3 \times 10^{4}

= 2.23 \times 10^{5} (Answer)
