What is the area of the triangle?

Luda [366]

Answer:

270cm^2

Step-by-step explanation:

The side length is irrelevant and does not matter.

The area of a triangle is found by multiplying the base by the height and then dividing that by two.

For this problem it would be...

30*18=540

540/2=270

So the area would be 270cm^2

At the beginning of year 1, Josie invests $400 at an annual compound interest

zvonat [6]

Answer:

The explicit formula that can be used is $A=\$400(1.05)^{2}$

The account's balance at the beginning of year 3 is $A=\$441$

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

in this problem we have

$t=2\ years\\ P=\$400\\ r=0.05\\n=1$

substitute in the formula above

$A=\$400(1+\frac{0.05}{1})^{1*2}$

$A=\$400(1.05)^{2}$

$A=\$441$

Answer:

$slope (m) = -\frac{3}{4}$

Step-by-step explanation:

Slope of the line using two pairs of values from the table, (-2, 5) and (2, 2):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{2 - (-2)} = \frac{-3}{4}$

$slope (m) = -\frac{3}{4}$
