Two math students were asked to write an exponential growth equation that had a starting value of 300 and a growth rate of 2%. P

Gemiola [76]

Answer:

Pierre is right

Step-by-step explanation:

The correct formula for Exponential growth rate is given as:

y = a( 1 + r) ^t

Where

y = Amount after time t

a = Initial amount

r = Growth rate

t = time

From the question

a = 300

r = 2% = 0.02

Hence, our exponential growth rate =

y = 300( 1 + 0.02)^t

y = 300( 1.02)^t

Therefore, Pierre is right

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.

charle [14.2K]

The area of a triangle could be determined using the following formula
$\boxed{a= \frac{1}{2} \times b \times h}$

plug in the numbers
$a = \frac{1}{2} \times 21 \times 12$
$a = \frac{1}{2} \times 252$
$a= \frac{252}{2}$
a = 126

The area of the triangle is 126 square meters

Can I get help with this?

blagie [28]

Answer:

y-4=7(x-1)

Step-by-step explanation:

Hi there!

We are given the slope of the line (7) and the point (1,4) and we need to find the equation in point-slope form.

Point-slope form is given as y- $y_{1}$ =m(x- $x_{1}$ ) where m is the slope and ( $x_{1}$ , $y_{1}$ ) is a point

We have all of the needed information for the equation, but let's first label the values of everything in order to avoid confusion

m=7

$x_{1}$ =1

$y_{1}$ =4

now substitute into the formula:

Hope this helps! :)

Answer:

c = 2
segments 10, 8, 6 (top down)

Step-by-step explanation:

The sum of top and bottom bases is twice the midsegment.

(c² +6) +(c² +2) = 2(4c)

2c² -8c +8 = 0 . . . . . . . . . subtract 8c

2(c -2)² = 0 . . . . . . . . factor

c = 2 . . . . . . the value that makes the binomial be zero

The value of c is 2; the segment lengths (top-down) are 10, 8, 6.
