Answer:

k(x)=5+4\sqrt{x}

Step-by-step explanation:

Write a function whose k(x) values are 5 more than four times the principal square root of x.

So,

the principal square root of x =\sqrt{x};

four times the principal square root of x =4\sqrt{x};

5 more than four times the principal square root of x =5+4\sqrt{x};

Thus,

k(x)=5+4\sqrt{x}

Maurinko [17]

Answer:

336 square inches

Step-by-step explanation:

Nets are the spreaded out version/outline of 3d figures. It shows the faces of the figure. The figure in this case is actually a triangular prism.

find the area of each shape in the net:

Triangle A (1/2 x base x height)

1/2 • 8 x 6 = 24 square inches

Rectangle B (length x width):

6 x 12 = 72 square inches

Rectangle C:

8 x 12 = 96 square inches

Rectangle D:

10 x 12 = 120 square inches

Triangle E:

1/2 x 6 x 8 = 24 square inches

Add up all the areas of all shapes:

24 + 24 + 120 + 72 + 96 = 336

Surface area is measured in square inches

(Inches in this case)

aleksandr82 [10.1K]

Answer:

B .62.5 m

Step-by-step explanation:

convert Kmh-1 in to ms-1

30 Kmh-1 = (30×1000) ÷3600 = 8.3ms-1

60 Kmh-1 = (60×1000) ÷3600 = 16.6 ms-1

acceleration = (16.6 - 8.3) ÷ 5 = 1.66 ms-2

V^2 = U^2 +2aS

(16.6)^2 = (8.3)^2 + 2×1.66 ×S

S = 62.5 m
