5 0

Answer:(0,0) (-1,0) (-1,3)

Step-by-step explanation:

scf 0.5 is shrinking the shape by a 1/2

The coordinates of a point of enlargment is (3,1)

so you work out the vectors of each corner than times it by 0.5

The vector of one cooridnate is (-6 -2)

-6x0.5=-3

-2x0.5=-1

so the vector is -3 -1 from the point of enlargment is the shape .

(-8 -2 ) is the coodinates of the next vector so

(-4 -1)

Then the last

(-8, 4)

(-4,2) vector for the last coodinate

sorry i couldn't write out the vector properly in the right notation .

Log 200 ~ 2.301<br> Write in exponential form

Luda [366]

Answer:

It can't be answered because it has to have a variable or number after log200 because that's how you get 2.301.

Step-by-step explanation:

Give me the variable or number and I'll answer it from there.

Need help question #3. Show steps please

Oksana_A [137]

Answer:

Step-by-step explanation:

We are given:

$\displaystyle \int \sqrt{x}\Big(9x^3-2\sqrt{x}+\frac{8}{x}\Big)\, dx$

And we want to select its equivalent form.

Note that A is not valid. No integration property allows us to separate factors unless that factor is a constant.

We can simply rewrite and then distribute. First, by rewriting:

$\displaystyle =\int x^{1/2}\Big(9x^3-2x^{1/2}+8x^{-1}\Big)\, dx$

Distribute. Recall exponent properties;

$\displaystyle =\int(9x^{3+1/2}-2x^{1/2+1/2}+8x^{-1+1/2})\, dx$

Simplify:

$\displaystyle=\int9x^{7/2}-2x+8x^{1/2}\, dx$

This can then be separated (since its addition/subtraction) and integrated individually.

Hence, our answer is B.

a television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the scre

Grace [21]

Answer: $75\%$

Step-by-step explanation:

You know that the ratio of the television's screen is $5:4$ . This ratio can be also written as the following fraction:

$\frac{5}{4}$

The television shows an image with a ratio of $20:12$ which can be also written as a fraction:

$\frac{20}{12}$

Set up the following proportion and solve for "x":

$\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16$

Now, in order to find the percent of the screen area occupied make the following division:

$\% occupied=\frac{12}{16}*100=75\%$
