r-ruslan [8.4K]3 years ago
7 0

Answer:

Not quite sure what you're meant to solve for, but my solution is below.

Step-by-step explanation:

The square root of a value squared is the absolute value of that value, because squaring removes all negatives. Therefore:

\sqrt{(y+2)^2}=c

\mid y+2\mid=c

\mid y\mid =c-2

Hope this helps!

A 12-inch diameter pizza has 22 calories per square inch.
kipiarov [429]

Answer:

2,486.88\ calories

Step-by-step explanation:

step 1

<u>Find the area of the pizza</u>

The area of a circle is equal to

A=\pi r^{2}

we have

r=12/2=6\ in

substitute

A=(3.14)(6^{2})=113.04\ in^{2}

step 2

we know that

A 12-inch diameter has 22 calories per square inch

By proportion

Find how many calories are in the entire pizza

so

\frac{22}{1}\frac{cal}{\ in^{2}}=\frac{x}{113.04}\frac{cal}{\ in^{2}}\\ \\x=22*113.04\\ \\x=2,486.88\ calories

Mice and Pain Can you tell if a mouse is in pain by looking at its facial expression? A new study believes you can. The study1 c
kotykmax [81]

<u>Explanation:</u>

1. a) Null hypothesis: There is <em>no</em> statistically significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

b) Alternate hypothesis: There is a statistically-significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

2. Yes, because a statistically significant data implies that there is sufficient evidence to believe the study, based on the results of the findings.

3. No, since the variables are different in this case. Here we are dealing with a non-painful solution so there may be no sample correlation as extreme as that found in the original study.

4. Possibly, because every hypothesis is an assumption until it is proven. Thus, in every statistical research, there may be different findings.

Find the height of ABD
Mila [183]

Answer:

Height=\boxed{10\sqrt{2}}

Area =\boxed{165\sqrt{2}}

Step-by-step explanation:

By geometric mean theorem:

AC=\sqrt{25\times 8}

AC=\sqrt{5^2 \times 2^2 \times 2}

AC=5\times 2\sqrt{2}

AC=10\sqrt{2}

So,

Height=\boxed{10\sqrt{2}}

Area = \frac{1}{2} \times base\times height

\therefore Area = \frac{1}{2} \times (25+8)\times 10\sqrt{2}

\therefore Area =33\times 5\sqrt{2}

Area =\boxed{165\sqrt{2}}
