okay so the problem is "A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is
Nesterboy [21]

Answer:

A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.

Step-by-step explanation:

equation of circle is

(X-center_X)^2 + (y-center_Y)^2 = r^2

==> (x+3)^2 + (y-2)^2 = r^2

Now it passes 1,5 so

4^2+3^2 = 5^2

==> r = 5

when x = -7

y = -1 or 5

The ratio of boys to girls in a group is 2:1. If there are 18 more boys than girls, work out how many girls there are.
Alborosie

Answer:

I think its 18, because if there's 2 boys to 1 girl then if there's 18 girls then there is an equivalent 18 boys to match, plus another 18, which would put the ratio of boy to girl at 2:1

Oliva is a stockbrocker. She makes 4% of her sales in commission.Last week,she sold $7,200 worth of stocks.
belka [17]

A) Commission made last week is $ 288

B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

<em><u>Solution:</u></em>

From given,

Commission rate = 4 %

Last week,she sold $7,200 worth of stocks

<em><u>A. ) How much commission did she make last week?</u></em>

Therefore,

Commission\ amount = 4 \% of\ 7200\\\\Commission\ amount = 4 \% \times 7200\\\\Commission\ amount = \frac{4}{100} \times 7200\\\\Commission\ amount = 4 \times 72\\\\Commission\ amount = 288

Thus commission made last week is $ 288

B)

Given that,

If she were to average that same commission each week

To find the commissions earned in a year, treating a year as having exactly 52 weeks

Therefore,

commissions\ earned\ in\ a\ year = 288 \times 52\\\\commissions\ earned\ in\ a\ year = 14976

Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

What are the values of x in the equation 4x2 4x – 3 = 0? x = –1.5, 0.5 x = –0.5, –1.5 x = x =?
Stolb23 [73]

Answer:

The values of x are

x=-1.5\ , 0.5

Step-by-step explanation:

we have

4x^{2}+4x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

4x^{2}+4x=3

Factor the leading coefficient

4(x^{2}+x)=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

4(x^{2}+x+.25)=3+1

4(x^{2}+x+.25)=4

(x^{2}+x+.25)=1

Rewrite as perfect squares

(x+0.5)^{2}=1

Square root both sides

x+0.5=(+/-)1

x=-0.5(+/-)1

x=-0.5+1=0.5

x=-0.5-1=-1.5
