True [87]3 years ago
8 0

Answer:

r = 5

Step-by-step explanation:

The formula for volume of a cone is \pi r^2*\frac{h}{3}

h = 6

V = 50π

2\pi r^2=50\pi

r = 5

Find the first 4 terms of the sequence.t(n) = -3n- 1b. t(15)=
aliya0001 [1]

Answer:

(a)-4, -7, -10 and -13.

(b) -46

Explanation:

Given the sequence:

t\mleft(n\mright)=-3n-1

(a) The first four terms are obtained by substituting n=1,2,3 and 4 respectively.

\begin{gathered} t\mleft(1\mright)=-3(1)-1=-3-1=-4 \\ t(2)=-3(2)-1=-6-1=-7 \\ t(3)=-3(3)-1=-9-1=-10 \\ t(4)=-3(4)-1=-12-1=-13 \end{gathered}

The first 4 terms of the sequence are -4, -7, -10 and -13.

(b)t(15)

\begin{gathered} t(15)=-3(15)-1 \\ =-45-1 \\ =-46 \end{gathered}

3. Write the equation of a line that passes through the point (24, 25) and is
IceJOKER [234]

Answer:

y=-1/3x + 33

Step-by-step explanation:

You can start by writing this in point slope form and converting to slope intercept later. Since the slope of the perpendicular line is y=3x-30, this line must have a slope of -1/3. It's point slope form is therefore:

y-25=-1/3(x-24)

Now, you can convert to slope intercept by isolating y:

y=-1/3(x-24)+25

y=-1/3x+8+25

y=-1/3x+33

Hope this helps!
