MATH!!! 15 points ;)) find the volume of the composite figure

andrezito [222]

Answer:

(2*2*1.5*1/3)+(2*1.5*4)= 14

Step-by-step explanation:

To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.

Which is the equation of the graphed line written in standard form? y = x x – 1/2y = 0 x – y = 0 y =1/2x

Airida [17]

The standard for of this equation is x – y = 0

Firstly, options A and D are not in standard form, so they are not options.

To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).

x – y = 0

2 - 2 = 0

0 = 0

This is true for option C. Therefore, it is correct.

Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual int

taurus [48]

Answer:

You should choose an account with a 7% annual interest rate which is compounded quarterly

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

part 1)

we have

$t=15\ years\\ P=\$14,000\\ r=0.07\\n=4$

substitute in the formula above

$A=14,000(1+\frac{0.07}{4})^{4*15}$

$A=14,000(1.0175)^{60}$

$A=\$39,645.43$

part 2)

we have

$t=15\ years\\ P=\$14,000\\ r=0.068\\n=12$

substitute in the formula above

$A=14,000(1+\frac{0.068}{12})^{12*15}$

$A=14,000(1.0057)^{180}$

$A=\$38,713.11$
