Answer:

one real solution

Step-by-step explanation:

We can use the discriminant to find the types of solutions

b^2 -4ac where ax^2 +bx+c=0

Since

x^2 -8x+16 =0

we know a=1 b=-8 and c=16

(-8)^2 - 4(1)(16)

64 -64 = 0

If the discriminant > 0 we have two real solutions

If the discriminant = 0 we have 1 real solutions

If the discriminant < 0 we have two complex solutions

Since it equals zero, we have one real solution

Answer:

One real solution because the answer is $(x-4)^{2}$

Step-by-step explanation:

$x^{2} -8x+16=\\(x-4)(x-4)$

Answer:

Step-by-step explanation:

$\huge {c}^{ \frac{1}{2} } + {c}^{ \frac{1}{3} } \\ \\ \huge = {64}^{ \frac{1}{2} } + {64}^{ \frac{1}{3} } \\(plug \: c = 64) \\ \\ \huge = { ({8}^{2}) }^{ \frac{1}{2} } + {( {4}^{3} )}^{ \frac{1}{3} } \\ \\ \huge = {8}^{2 \times \frac{1}{2} } + {4}^{3 \times \frac{1}{3} } \\ \\ \huge = 8 + 4 \\ \\ \huge = 12$

The two box-and-whisker plots below represent the distribution of shoe sizes for a group of 40 two-year-old boys and a group of

<h3>Answer: Choice B) 0.5</h3>

=============================================================

Explanation:

For now, focus solely on the orange boxplot. The first quartile Q1 is the left edge of the box, which is at 3.5; while the value of Q3 is 7.5 (right edge of the box). The interquarile range (IQR) is ...

IQR = Q3 - Q1

IQR = 7.5 - 3.5

IQR = 4

This is basically the width of the box. Ignore the whiskers when it comes to the IQR.

Let A = 4 as we'll use it later.

---------------------------------

Find the IQR for the blue box plot

Q1 = 6 = left edge of the blue box

Q3 = 9.5 = right edge of the blue box

IQR = Q3 - Q1

IQR = 9.5 - 6

IQR = 3.5

Let B = 3.5 as we'll use it later

---------------------------------

Subtract the values of A and B to find the difference of the IQR values

A - B = 4 - 3.5 = 0.5

Suppose the radius of a circle is \color{purple}{3}3start color purple, 3, end color purple. What is its diameter?

Varvara68 [4.7K]

The number of a radius is half of the diameter. so 3 is half of 6. your diameter is 6.
