Answer:

Exact value,  \angle B=\sin^{-1}(\frac{3}{4})

Approximation,  \angle B\approx 48.6^\circ

Step-by-step explanation:

In ΔABC, ∠C=90°

We are given a right angle triangle.

Side AB is hypotenuse = 4

Side AC is one leg = 3

Using trigonometry identity:

\sin\angle B=\dfrac{Perpendicular}{Hypotenuse}

\sin\angle B=\dfrac{AC}{AB}

\sin \angle B=\dfrac{3}{4}

\angle B=\sin^{-1}(\frac{3}{4})

\angle B=48.59^\circ\approx 48.6^\circ

The exact value of \angle B=\sin^{-1}(\frac{3}{4})

The approximation of \angle B\approx 48.6^\circ

The piecewise defined function is

f(t) = 800 * 1.5^t for 0 - 2

f(t) = 2700 * 1.05^t-3 for 3 to 9

<h3>How to determine the piecewise functions?</h3>

On the domain of t = 0 to 2, we have:

f(0) = 800

f(1) = 1200

f(2) = 1800

The above function is a piecewise function with the following definition

f(0) = 800 --- initial value

r = 1200/800 = 1.5 --- rate

The function is then represented as:

f(t) = f(0) * r^t

This gives

f(t) = 800 * 1.5^t

On the domain of t = 3 to 9, we have:

f(3) = 2700

f(4) = 2835

The above function is a piecewise function with the following definition

f(3) = 800 --- initial value

r = 2835/2700 = 1.05 --- rate

The function is then represented as:

f(t) = f(3) * r^t-3

This gives

f(t) = 2700 * 1.05^t-3

Hence, the piecewise defined function is

f(t) = 800 * 1.5^t for 0 - 2

f(t) = 2700 * 1.05^t-3 for 3 to 9

I’ll give brainliest but plz help me I would be so grateful!
Nesterboy [21]

Answer:

1. a

2. c

3. e

Step-by-step explanation:

1. a because she ran 5 miles on friday and ran x miles before friday. we know she had ran a total of 20 miles so we have x+5=20

2. there is a total of 20 clubs andre's school, 5 times more than is cousin's school. we have 20 =5x

3. 20 cats get 5 cups of food. each got an x amount. we get 5 =20x

Find the value of x and the measure of the angel labeled 6x. A. X=5; angle measure is 42 B. X=5; angel measure is 72 C. X= 5; an
Sergeu [11.5K]

Answer:

x = 5

angle measure labelled 6x is 30degrees

Step-by-step explanation:

Find the diagram attached

from the diagram;

6x = 30 (vertically opposite angle)

Divide both sides by 6

6x/6 = 30/6

x = 5

Get the angle labelled 6x

6x = 6(5)

6x = 30degrees

Pablo built a large wooden storage box. The box was in the shape of a rectangular prism, as shown below. He covered all the side
Naily [24]

The cost of wallpaper used to cover all sides of the storage box is given by $3 per square foot

<h3>Cost of wallpaper per square foot</h3>

  • length = 9 ft
  • Width = 8 ft
  • Height = 5 ft

Surface area of a box = 2(lh + wh + lw)

= 2(9×5 + 8×5 + 9×8)

= 2(45 + 40 + 72)

= 2(157)

= 314 square foot

  • Total cost of wallpaper = $942

Cost of wallpaper per square foot = $942 ÷ 314 square foot

= $3 per square foot

At A Local Restaurant, The Health Inspector Visits Every 7 Days, And The Fire Inspector Visits Every 12 Days.
Xelga [282]
 PART A :OK so here is the table for the health inspector; all you are really doing is 7+7+7, and so on:

PART A: health inspector: 7,14,21,28,35,42,49,56,63,70,77,84..........

PART A:same thing for the fire inspector, except this time your adding 12+12+12, and so on:

PART A: fire inspector: 12,24,36,48,60,72,84,96.......

PART B: and to figure out what day they will both come is you have to find the LCM (least common multiple)

PART B: which in this case is Day 84

hopes this helps!!!!!
