Gre4nikov [31]3 years ago
7 0

Answer:

Step-by-step explanation:

The base of a cone is simply a circle.

The formula for the area of a circle is A = πr^2.

Example:  What is the area of the base of a cone, if the radius of the base is 5 cm?

Answer:   A = π(5 cm)^2 = 25π cm^2

A. There is a positive correlation between the temperature and the amount of ice cream sold. This means that as the temperature increases the amount of ice cream also increases.

B. For the best fit you must calculate the slope between two points that are more-or-less representative of the entire graph.  In this case it seems to have already done this with certain points so if you take the points (15,35) and (0,5) you can calculate the slope between these two points which is m=(35-5)/(15-0)=30/15=2.  So the best fit slope for this particular case would be two and you would just draw a line through the graph at approximately the middle of the dots to best represent all of the data.

and the y-intercept is 5 so the approximate equation for the graph would be y=2x+5

Y = f(x) = 16x Find f(x) when x = 1/2​
Alina [70]

Answer:

The answer depends on what the problem really is.

f(1/2) = 8

or

f(1/2) = 4

See below.

Step-by-step explanation:

This is the problem as it was posted:

y = f(x) = 16x

Let x = 1/2

y = f(1/2) = 16(1/2) = 8

Perhaps the problem is this:

y = f(x) = 16^x

If x is an exponent of 16 and not a factor, then the answer is:

y = f(\frac{1}{2}) = 16^\frac{1}{2} = \sqrt{16} = 4

Twice the difference of a number and 9 is at least 17.
victus00 [196]

Answer:

x ≥ 12.5

Step-by-step explanation:

2(x-9) ≥ 17---Use Distributive Property

2x-18 ≥ 17

2x-18+18 ≥ 17+18

2x ≥ 25

2x/2 ≥ 25/2

x ≥ 12.5

I hope this helps!

A 3ft child casts a 2ft shadow at the same time a tree casts a shadow that is 6ft long how tall is the tree?
Anettt [7]

Answer:

h_t=9ft

Step-by-step explanation:

From the question we are told that:

Height of child h_c=3ft

Height of child's shadow  h_c_s=2ft

Height of tree's shadow h_t_s=6ft

Since position of Sun remains constant  

Generally the equation for Height of tree h_t mathematically given by

 h_t=f_{ts}\frac{h_c}{h_c_s}

 h_t=6*\frac{3}{2}

 h_t=9ft
