Answer:

Step-by-step explanation:

Commutative property of addition:  The order in which you add these fractions together doesn't matter.

I would combine 3/5 and 2/5 first, as that readily results in 5/5, or just 1.

Then we have 1 1/4, or 1.25, or 5/4 as the final answer.

State the equation of the following graphs.<br> Someone please help ASAP
Vaselesa [24]
Answer

y = 1(x +1) - 3

Explanation

A quadratic equation of the form y = ax^2 + bx + c

This written in complete the square form provides you with the vertex (either a maximum or minimum point depending on the equation).

This results in y = a(x + p) + q

Where - p is the x value and q is the y value of turning point.

For graph 22, x = -1 and y = -3

Therefore, the equation is of the form

y = a(x + 1) - 3 (*)

We still need the value a, this can be obtained by using the y-intercept we are given.

We are told x = 0 when y = -2

Substitute this in (*) equation:

-2 = a(0+1) - 3

-2 = a - 3

a = 1

Therefore final equation is

y = 1(x +1) - 3

This should provide you with the train of thought of how the second question should also be tackled.

If unsure about why the equation
y = a(x + p) + q gives the vertex ask in comments I will respond

Find the area of a circle with diameter 12 cm.
luda_lava [24]

Answer:

113.04 cm.

Step-by-step explanation:

Step 1: <u>Formula/explain</u>

To find the area of a circle, multiply the radius by itself twice, then multiply the product pi.

a=\pi r^2(3.14*radius*radius)

Step 2: <u>Solve</u>

According to the word problem, the circle has a diameter of 12. This means it has a radius of 6.

Now, we plug the numbers into formula.

\pi 6^2 (3.14*6*6)=113.04

Step 3: <u>Conclude</u>

Therefore, the area of this circle is 113.04 cm.

Solve the quadratic equation.<br>m^2/15 -3 = 2​
Radda [10]

The answer is 5 \sqrt{3}

<h3>Explanation :</h3>

\frac{ {m}^{2} }{15}  - 3 = 2

\frac{ {m}^{2} }{15}  = 2  + 3

\frac{ {m}^{2} }{15}  = 5

{m}^{2}  = 5 \times 15

{m}^{2}  = 75

m =  \sqrt{75}

m =  \sqrt{25 \times 3}

m =  \sqrt{25}  \times  \sqrt{3}

m = 5 \sqrt{3}
