How do you find the answer

KengaRu [80]

You need to measure the angles wich means that u use a protractor if the angle is 90 degrees is a straight angle if it is below 90 degrees is acute and if it is above 90 degrees it's obtuse

Alfonso is 8 years older than Ashley. Five years ago Alfonso was three times as old as Ashley. How old is Ashley now?

Pavel [41]

Answer: 9 years

Step-by-step explanation:

Let the present age of Ashley be x.

Then the present age of Alfonso =x+8

Five years ago,

Ashley's age = x-5

Alfonso's age = x+8-5 = x+3

According to the question,

$x+3=3(x-5)\\\Rightarrow\ x+3=3x-15\\\Rightarrow\ 3x-x=3+15\\\Rightarrow\ 2x=18\\\Rightarrow\ x=\frac{18}{2}\\\Rightarrow\ x=9$

Hence, the present age of Ashley =9 years

A family wants to save for college tuition for their daughter. What continuous yearly interest rate r% is needed in their saving

sergey [27]

Answer:

The continuous yearly interest is 22.5% per year.

Step-by-step explanation:

Continuous yearly interest:

Continuous yearly interest is defined as the sum of the interest comes from principle and the interest comes from interest.

The formula for continuous interest yearly is

$A=Pe^{rt}$

where A = The final amount =$110,000

P= principle =$4,700

r= rate of interest

t= time (in year)= 14 years

$\therefore 110,000= 4,700e^{r\times 14}$

$\Rightarrow e^{14r}= \frac{110,000}{4,700}$

Taking ln both sides

$\Rightarrow ln e^{14r}= ln(\frac{110,000}{4,700})$

$\Rightarrow {14r}= ln(\frac{1100}{47})$

$\Rightarrow r=\frac{ln( \frac{1100}{47})}{14}$

$\Rightarrow r = 0.225$ (approx)

The continuous yearly interest is 0.225 = 22.5% per year.

Graph the image using the given transformation

love history [14]

1) First find the coordinates of the shape:

G(-1, -2), F(-1, -1), E(2,2), D(2, -2)

2)It asked for dilation of 2 about the origin.

*What is dilation?

Dilation is the expanding/enlarging a transformation by a scale factor

Now we multiply all the coordinates with the factor of 2

G(-1*2, -2*2) = G'(-2, -4)

F(-1*2, -1*2) = F'(-2, -2)

E(2*2, 2*2) = E'(4, 4)

D(2*2, -2*2) = D'(4, -4)

3) Now plot these points and graph the transformation:
