whats the center radius of the circle

Answer:

1) -15+8i

2) x^2+2x-5

Step-by-step explanation:

1) apply perfect square formula

(4i)^2+2*4i1+1^2

then simplify

2)remove parentheses

x+1+(x-2)(x+3)

expand (x-2)(x+3)

x+1+x^2+x-6

simplify x+1+x^2-6 = x^2+2x-5

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

Step-by-step explanation:

Answer:

(1) First pair; (2, 3), (7, 3), d₁ = 5

(2) Second pair; (-2, 5), (-2, -3), d₂ = 8

(3) Third pair; (-8, 5), (-2, 5), d₃ = 6

(4) Fourth pair; (-9, 1), (6, 1), d₄ = 15

Step-by-step explanation:

Given pair of points;

(1)  (2, 3), (7, 3)

(2) (-2, 5), (-2, -3)

(3) (-8, 5), (-2, 5)

(4) ) (-9, 1), (6, 1)

The distance between each pair of points is calculated as follows;

[tex]d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2}[/tex]

(1) first pair; (2, 3), (7, 3)

[tex]d_1 = \sqrt{(3-3)^2 + (7-2)^2} \\\\d_1 = 5[/tex]

(2) second pair; (-2, 5), (-2, -3)

[tex]d_2 = \sqrt{(-3-5)^2 + (-2-(-2))^2}\\\\d_2 = \sqrt{(-3-5)^2 + (-2+2)^2} \\\\d_2 = 8[/tex]

(3) Third pair; (-8, 5), (-2, 5)

[tex]d_3 = \sqrt{(5-5)^2 + (-2-(-8))^2}\\\\d_3 = \sqrt{(5-5)^2 + (-2+8)^2} \\\\d_3 = 6[/tex]

(4) Fourth pair; (-9, 1), (6, 1)

[tex]d_4 = \sqrt{(1-1)^2 + (6-(-9))^2}\\\\d_4 = \sqrt{(1-1)^2 + (6+9)^2} \\\\d_4 = 15[/tex]

Step-by-step explanation:

Answer:

n = 7 1/3 weeks

Step-by-step explanation:

Amount Jabari wants to save = $66

Amount he earns per week = $9

Hours worked per week = 2 hours

How many weeks will it take him to save $66?

Let

n = number of weeks will it take him to save $66

66 = 9n

n = 66/9

n = 7 3/9

n = 7 1/3 weeks

Or

n = 7.33 weeks

Answer:

C. Log base b (a) - Log base b (d)

Step-by-step explanation:

In logarithm, log means index or exponent. It can be explained with following example. Consider 2^5 = 32

here index = log = 5 so you can write the log of 32 = 5

Consider 64/16 = 4

now 64 = 2^6 and 16 = 2^4

We can write log 2(64) = 6 and log2(16)=4

Now log 64/16= log 4= 2

Also log2(64)-log2(16)=6-4=2

Therefore

Log base b (a/d) = Log base b (a) - Log base b (d)

The length of AC is 6.4 unit.

The correct option is C.

We have the figure from which we can say that

BD is the diameter which is

= 4.8 + 1.6

= 6.4 unit long.

Now, AC is the chord.

As, the distance between the two opposite point the the surface of circle would be same.

Then, the length of AC = length of BD

Thus, the length of AC is 6.4 unit.

Answer:

y=-1/6x

Step-by-step explanation:

To find the answer you can just look at 2 points on the graph and whichever one comes first is (y1,x1) and the next pair is (y2,x2). So to find it we can use (0,0) automatically because the line is crossing through it. We can also use (600,-100) as the second point becasue it is the next farthest away and when we plug the numbers into the slope equation(y2-y1/x2-x1) we get -100-0/600-0 which when simplified is -100/600 or -1/6 so that would be the m in slope-intercept form (y=mx+b) and when you get everything you can find the equation y=-1/6x
