Alice created a kite out of two sticks and some fabric. The sticks were 10 inches and 15 inches long.
DENIUS [597]

Answer:

Area = 25 square inches.

Step-by-step explanation:

Consider the large base triangle first. The height is 15 - 5 = 10

The base across is 10 (the length of the smaller stick).

The Area of that triangle is 1/2 * b * h

Area = 1/2 * 10 * 10 = 50

Now the smaller triangle is the same base (the smaller stick of 10) * the height of 5

Area = 1/2  b * h

Area = 1/2  10 * 5

Area = 25

total area of the kite = 50 + 25 = 75

What is the domain and range of f(x)=4^x-8
gladu [14]

If the function is: f(x) = 4^x     - 8

D = {XeR}
R = {YeR|Y≥0}


if the function is: <span>f(x)=4^(x-8)

</span>D = {XeR}
R = {YeR|Y≥ -8}

Hello i need help with question 5 asap!!
sergeinik [125]

Answer:

  arc DB length = 14π feet

Step-by-step explanation:

Assuming point A is the center of the circle, arc DC has measure 180°. Arc DB has measure 40° less, so is 140°. Since you want this in terms of π, we need to convert the degree measure to radians. We do that by multiplying by (π/180) radians per degree:

  arc DB = 140° = 140°(π/180°) radians

__

Now that we know the arc measure in radians, we can find the length of the arc. It is given by the formula ...

  s = rθ

where r represents the radius and θ is the measure of the arc in radians.

The arc length is ...

  s = (18 ft)(7π/9) = 14π ft

Arc DB has a length of 14π feet.
