Find the area of the composite figure in terms of the figure (use 3.14 for pi)​
svp [43]

Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

10\cdot8=80 ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is \pi r^2. The radius is 4, as the diameter is 8.

3.14\cdot4^2

3.14\cdot16

50.24\div2=25.12

Add 80 and 25.12:

80+25.12=105.12

Hope this helped!

Find the equation of the straight line that passes through the points (1, 10) and (3, 2)
slava [35]

Answer:

y = -4x+14

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

m = (2-10)/(3-1)

  =-8/2

  = -4

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -4x+b

Substitute a point into the equation

10 = -4(1)+b

Add 4 to each side

14 = b

y = -4x+14

If I = PRT/100, MAKE R THE SUBJECT OF THE FORMULA.​
Nonamiya [84]

Answer:

R = \frac{100I}{PT}

Step-by-step explanation:

I = \frac{PRT}{100} ( multiply both sides by 100 to clear the fraction )

100I = PRT ( isolate R by dividing both sides by PT )

\frac{100I}{PT} = R
