• She needs 45 points for a free movie ticket.
How many visits must Ashley make to earn a free movie ticket?

Answers

Answer:

Answers

Answer:

[tex]\%Rate = 0.0142\%[/tex]

Step-by-step explanation:

Given

[tex]Population = 183000[/tex]

[tex]New\ Cases = 26[/tex]

[tex]Active\ Cases = 264[/tex]

Required

The incidence rate

This is calculated as:

[tex]\%Rate = \frac{New\ Cases}{Population} * 100\%[/tex]

[tex]\%Rate = \frac{26}{183000} * 100\%[/tex]

[tex]\%Rate = 0.0001420765 * 100\%[/tex]

[tex]\%Rate = 0.01420765\%[/tex]

[tex]\%Rate = 0.0142\%[/tex] --- approximated

Hence, the incidence rate is 0.0142%

A' = (4, 4)

B' = (12, 4)

C' = (4, 10)

Step-by-step explanation:

Ok so you are given that the scale factor is 2. You will multiply 2 with the values given of point A, B, and C in order to find the value of point A', B', and C'.

A = (2, 2) ---> 2 × 2 = 4 and 2 × 2 = 4

A' = (4, 4)

B = (6, 2) ---> 6 × 2 = 12 and 2 × 2 = 4

B' = (12, 4)

C = (2, 5) ---> 2 × 2 = 4 and 5 × 2 = 10

C' = (4, 10)

DO NOT SOLVE and be specific in your explanation.
В І у
0 / 1000 Word

Answers

Answer:

You would either need to complete the square, use the quadratic equation, or another method because when reduced by the common factor, the constant term c is prime which means that it is only divisible by one and itself. Because the possible rational factors determined by c do not add up to the b term, it cannot be factored.

Explanation:

3x² + 24x - 15 = 0

3(x² + 8x - 5) = 0

[find the greatest common factor between each term and move the coefficient outside of the expression; in this case it's 3 since 3 fits into numbers 3, 24, and -15 so that it cannot be reduced further]

Then you can either use the box or pq method (since a is 1) to find working factors.

x² + bx + c → (x + p)(x + q).

p + q = b.

pq = c.

In this case with 3(x² + 8x - 5), b is 8 and c is -5.

This means we need two numbers that add up to 8 and multiply to -5.

Since -5 is prime, our only options are ±1 for p and ∓5 for q. This is because these are the only factors which multiply to -5.

1 + -5 = -4 ≠ 8

-1 + 5 = 4 ≠ 8.

Since we cannot find rational solutions, this cannot be factored, and so we must use another method.
