1) u would have to find the lcd of both. And that is 60 so it would be 25/60 +36/60 = 61/60 = 1 1/60

2) do the same thing as in number 1. Find the LCD it is 18. So 14/18 - 9/18 = 5/18

mina [271]

Answer:

A = 437 mm²

Step-by-step explanation:

The general formula for the area of a triangle:

A = \frac{1}{2}bh, where 'b' is the measure of the base and 'h' is the measure of the height

Given the dimensions of the triangle in the picture:

A = \frac{1}{2}(38)(23) = 437 mm²

Which of the following options results in a graph that shows exponential growth?
poizon [28]

Answer:

f(x)=0.7(5)^x

Step-by-step explanation:

\text{Exponential function: }y=a\cdot b^x

It is two types of function.

  • Exponential Growth: If function increase as value of x increase.

In this case, a>0 and b>1

  • Exponential decay: If function decrease as value of x increase.

In this case, a>0 and 0<b<1

We need to choose exponential growth function.

\text{Exponential Growth function: }f(x)=0.7(5)^x

Here a=0.75>0 and b=5>1

Therefore, This function is exponential growth.

Please Help Me ;-;
ANTONII [103]

slope  = (y2-y1)/(x2-x1)

      =  (2--1)/(5-1)

      = (2+1)/(4)

       =3/4


The point slope from of a line is

y-y1 = m(x-x1)

y--1 = 3/4 (x-1)

y+1 = 3/4 (x-1)
