Math question down below

Answer:

(A)

Step-by-step explanation:

To be honest, since all of them are different, as long as you get the first one right, you will get the others right. A is your answer, for the following reasons:

Reflexive Property: The Reflexive property states that the mirrored version of itself will always be congruent with itself. Generally, to make it easier, they will write it opposite (as they did in the given proof):

line AC ≅ line CA

~

Answer:

A

Step-by-step explanation:

AC and CA represent the same segment, therefore have the same length and hence are congruent

Last step should be CPCTC because that's what is to be proven

Step-by-step explanation:

Step 1:  Simplify the root

[tex]\frac{1}{10}*\sqrt{10000*a^1^0*b^1^0}[/tex]

[tex]\frac{1}{10} * \sqrt{100^2*(a^5)^2*(b^5)^2[/tex]

[tex]\frac{1}{10}*100*a^5*b^5[/tex]

[tex]10a^5b^5[/tex]

Answer:  [tex]10a^5b^5[/tex]

The answer is 100[tex]a^{5} b^{5}[/tex].

To simplify any algebraic expression, the following are the simple rules and steps: put off any grouping symbol inclusive of brackets and parentheses by means of multiplying elements. Use the exponent rule to take away grouping if the phrases are containing exponents.

Given

1 / 10 * √10000 *[tex]a^{10}[/tex] * [tex]b^{10}[/tex]

1 / 10 * 1000 *[tex]a^{5}[/tex] *[tex]b^{5}[/tex]

⇒ 100[tex]a^{5} b^{5}[/tex]

An expression is a set of terms combined using the operations.

Hey there! I'm happy to help you!

The formula for the volume of a sphere is [tex]V=\frac{4}{3} \pi r^{3}[/tex], which is the the radius cubed multiplied by pi and 4/3. There are a lot of interesting proof videos out there about how this formula is derived and it is super cool and you would love it!

If our radius is 8 centimeters, we can plug it in like this:

[tex]V=\frac{4}{3} \pi (8)^{3}[/tex]

I hope that this helps! Have a wonderful day!

If the current amount he has is B and its 7 LESS then he had earlier add 7 back to find the amount he add  at the start.

Answer:

b+7,Option 1

Step-by-step explanation:

Let the number of buttons Cole had at first be a,

We know,now he has b buttons remaining which is 7 less than a

In other words,

a-7=b

or,a=b+7

Answer:

42%

Step-by-step explanation:

1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50

to convert this into percentage multiply by 2 on both sides:

21*2=42

50*2=100

42/100=42%

42% of girls played in the league

hope this helps!

Answer:

$4785.68

Step-by-step explanation:

Original amount: $4230

Interest for 1 year: 4.2%

First year;

[tex]4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66[/tex]

Second year;

[tex]4407.66 + (4407.66 \times \frac{4.2}{100} ) \\ = 4407.66 + 185.12172 \\ = 4592.78172[/tex]

Third year (total balance after 3 years);

[tex]4592.78172 + (4592.78172 \times \frac{4.2}{100} ) \\ = 4592.78172 + 192.89683224 \\ =4785.67855224[/tex]

Round the number;

$4785.68

YOUR ANSWER hope this helps :))

Answer: 4785.68

Step-by-step explanation: simpler way

B = P x (1 + R)^t

P = Staring Amount

R = Interest Rate

T = Time

B = Balance

B = $4230 x (1 + 0.042)^T

Answer:

Step-by-step explanation:

the probability that the player will not win on Monday or Tuesday, but will win on Wednesday is the same as the probability of winning on the third trial.

This is an example of a geometric probability distribution because trials are repeated until the first success is gotten. Since chance of winning a prize on a given ticket is about 17%, it means that the probability of success, p = 17/100 = 0.17.

Let x represent the number of days before the person wins. The probability that it takes three days before the player wins is expressed as

P(x = 3)

By using the geometric distribution calculator,

P(x = 3) = 0.12

Answer:

g=1.25

Step-by-step explanation:

Divide 4 into 3.2

4/3.2=1.25

Try to use inverse operations to solve this problem.

First multiply both sides by g to get the g out from under the 4 The equation is now:

4=3.2g

From here then you divide both sides by 3.2.

The answer is g=1.25

Step-by-step explanation:

Answer:

y = -15.9x² + 110.48x + 3.02

initial velocity: 110.48 ft/s

initial height: 3.02 ft

time to cath the ball at 6 ft: 6.92

Step-by-step explanation:

In the picture attached, the plot of the data points and the equation of the best regression is shown, which correspond to a quadratic equation. (It was obtained using Excel)

The initial velocity is the second coefficient.

The initial height is the third coefficient.

Replacing y = 6 into the equation and solving with the quadratic formula:

6 = -15.9x² + 110.48x + 3.02

0 = -15.9x² + 110.48x + 3.02 - 6

0 = -15.9x² + 110.48x - 2.98

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex]x = \frac{-110.48 \pm \sqrt{110.48^2 - 4(-15.9)(-2.98)}}{2(-15.9)} [/tex]

[tex]x = \frac{-110.48 \pm 109.62}{-31.8} [/tex]

[tex]x_1 = \frac{-110.48 + 109.62}{-31.8} [/tex]

[tex]x_1 = 0.03[/tex]

[tex]x_2 = \frac{-110.48 - 109.62}{-31.8} [/tex]

[tex]x_2 = 6.92[/tex]

In the context of the problem, only x2 has sense.
