Find slope:

m = (5 - 3) / (4 - 0)

m = 2/4

m = 1/2

Y-intercept (b) is given:

(0,3)

b = 3

Plug in values to slope-intercept form:

y = (1/2)x + 3

Hope this helps!! :)

What is the exact volume of the cone? with a 5 ft radius and a 16 ft height

andrew11 [14]

Answer:

The volume is 418.93 ft^3

Step-by-step explanation:

Here, we want to find the volume of a cone

Mathematically, we use the formula;

V = 1/3 * pi * r^2 * h

r = 5 ft

h = 16 ft

Substituting these values;

V = 1/3 * 3.142 * 5^2 * 16

V = 418.93 ft^3

to find how much stephanie spends for first we will find how much probhjot spends and then subtract 3.45 dollars from that value alvin spends 2.60 dollars

prohbjot spends 4 times as much as alvin or

4× 2.60=10.4

so prohbjot spends 10.4 dollars

stephanie spends3.45 dollars less than prohbjot or

10.4 -3.45 =6.95

so stephanie spends <u>6.95 </u>dollars

0.15p = 175

p = 175/0.15 = 1166.67
