Let f(x)=x^2+5x−8. What is the average rate of change from x = 2 to x = 6?

Lena [83]

F(2)=4+10-8=6; f(6)=36+30-8=58. Average rate of change is (58-6)/(6-2)=52/4=13

Kayla wants to find the width, AB, of a river. She walks along the edge of the river 65 ft and marks point C. Then she walks 25

AlladinOne [14]

Answer:

Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles

Part B) The width of the river is about $39\ ft$

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

Part A) we know that

In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent

m<DCE=m<ACB -----> by vertical angles

m<EDC=m<ABC -----> is a right angle

m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees

Part B) we know that

The triangles ABC and EDC are similar -------> see Part A

therefore

$\frac{BC}{DC}=\frac{AB}{DE}$

substitute the values and solve for AB

$\frac{65}{25}=\frac{AB}{15}$

$AB=15*(\frac{65}{25})=39\ ft$

Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply. A. 400 • 0.32 B. 4

irina1246 [14]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Original price of a telescope = $400

Mark up percent = 32%

So, Price after mark-up is given by

$400\times \frac{100+32}{100}\\\\=400\times \frac{132}{100}\\\\=400\times 1.32\\\\=\$528$

Hence, Option 'C' is correct.
