Does any one know the answer

Mathematics
1 answer:
gregori [183]3 years ago
6 0

Answer:

Step-by-step explanation:

Solve for x=0 and x=1

y(0)=2(3^0)=2(1)=2 so (0,2) is a point.

y(1)=2(3^1)=2(3)=6 so (1,6) is a point.

Only graph B has those two points.

If A and B are supplementary angles and A is four times as large as ​B, find the measures of A and B.
lora16 [44]

Answer: Angle A= 135 degrees and Angle B= 45 degrees

Step-by-step explanation:

Supplementary means two angles added together to make 180.

Angle A= 3x  and Angle B= x

So 3x +x =180

4x=180 divide both sides by 4

x =45

So Angle A = 3 times 45 =135 degrees

Angle B= the value of x which is 45 degrees

Find the lenght of side BC. give your answer to 3 significant figures
Serga [27]

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = \frac{adjacent}{hypotenuse} = \frac{AB}{BC} = \frac{6.3}{BC} ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = \frac{6.3}{cos71} ≈ 19.4 cm ( to 3 significant figures )
