Answer 1

Answer:

Answer:

(A)

Step-by-step explanation:

To find the range, you have to subtract the highest value from the list (85) from the lowest value (15) When you subtract these values you get 70, which is the range.

To find the mid-range, you add the highest value from the list (85) and the lowest value (15) When you add these values, you get 100. You then have to divide the sum of the highest and lowest value (100) by 2. When you divide the sum of the highest and lowest value by 2 you get 50, which is the mid-range.

Hope this helps!

Answers

Finding the least common denominator-
What is the smallest number that all denominators can go into? Well I see that the 2/3 has a relation to 5/6. ( 3 * 2 = 6 ).

4 (9/4) does not have a relation to the 6 in 5/6. So, what is the smallest number that 6 and 4 can go into? I see that it is 12. So the answer is 12.
All three numbers, 4, 6, and 3 can go into 12 and 12 is the smallest.

Answer:

b = 2

c = 6

Step-by-step explanation:

the possible value of c = 6 or 8 (positive, even, single-digit number & higher than a)
a = 4

[1]

a + b = c

4 + b = 6

b = 2 (meet all requirements)

[2]

a + b = c

4 + b = 8

b = 4 (not valid, because a = b)

b = 2

c = 6

The first three steps in writing f(x) = 40x + 5x2 in vertex form are shown.Write the function in standard form. f(x) = 5x2 + 40x
Factor a out of the first two terms. f(x) = 5(x2 + 8x)
Form a perfect square trinomial. = 16
f(x) = 5(x2 + 8x + 16) – 5(16)
What is the function written in vertex form?

A.f(x) = 5(x + 4) – 80
B.f(x) = 5(x + 8) – 80
C.f(x) = 5(x + 4)2 – 80
D.f(x) = 5(x + 8)2 – 80

Answers

The right answer for the question that is being asked and shown above is that: "C.f(x) = 5(x + 4)2 – 80." Write the function in standard form. f(x) = 5x2 + 40x. Factor a out of the first two terms. f(x) = 5(x2 + 8x). Form a perfect square trinomial. = 16. f(x) = 5(x2 + 8x + 16) – 5(16). The vertex form is C.f(x) = 5(x + 4)2 – 80

Use the formula $(a+b)^2=a^2+2ab+b^2$ for quadratic trinomial. Then you can form from a quadratic trinomial perfect square:

$x^2 + 8x + 16=x^2+2\cdot x\cdot 4+4^2=(x+4)^2$ .

From the last given step you have that

$f(x) = 5(x^2 + 8x + 16)-5\cdot 16$ .

Since 5·16=80, you can substitute the previous expression for perfect square into function expression and get:

$f(x)=5(x+4)^2-80$ .

This means, when x=-4, f(-4)=-80 and vertex has coordinates (-4,-80).

Answer: correct choice is C.
