Answer:

y = 2x^2 + 4x - 2  

Step-by-step explanation:

y=2(x+1)^(2)-4 is in vertex form.  We want the same equation in standard form, which looks like y = ax^2 + bx + c.

Perform the indicated multiplication (squaring of x + 1):

y = 2(x^2 + 2x + 1) - 4, or

y = 2x^2 + 4x + 2 - 4, or

y = 2x^2 + 4x - 2                   This is in the standard form of a quadatic.

Answer:

Likely to get it.

Step-by-step explanation

Do you mean 1% or 1? If 1 then it is likely to pick that.

If it is 1% then it's the opposite (unlikely) to pick that.

Hopes this makes sense!

Answer:

956.73

Step-by-step explanation:

0.3% = 0.003

1-0.003 = 0.997

49/6 = 8 r1 (use 8 because decay is not continuous)

0.997^8 = 0.97625...

0.97625... x 980 ≈ 956.73

Answer:

y + 5 = -3(x - 0)

Step-by-step explanation:

First, you find the slope. To do that, you subtract the second y point (in this case 4) by the first y point (in this case -5), and you get 9. Then, you subtract the second x point (in this case -3) by the first x point (in this case 0), and you get -3. Y is over X, so you get 9/-3 or 9 over -3, which can simplify to -3.

Next, you use the point slope formula: y - y1 = m(x - x1). Add in the y1, m, and x1, then solve if it asks you to put it in slope intercept form. So, for this case, it would be y + 5 = -3(x - 0)

Answer:

x= 7

x=-1

Step-by-step explanation:

- Multiply the coefficient of the first term by the constant   1  -7 = -7

- Find two factors of  -7  whose sum equals the coefficient of the middle term, which is   -6 .

-7+ 1 = -6

-Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  1.

x^2-7x+1x-7

- Add up the first 2 terms, pulling out like factors.

Answer:

Total students = 1240

Step-by-step explanation:

Given that,

Number of boys: number of girls=11:9

[tex]\dfrac{x}{y}=\dfrac{11}{9}\\\\9x=11y[/tex] ......(1)

There are 124 more boys than girls i.e.

x = 124+y .....(2)

Put the value of x from equation (2) in equation (1). So,

9(124+y) = 11y

1116 +9y = 11y

1116 = 2y

y = 558

Put the value of y in equation (2).

x = 124+558

x = 682

Total students = x+y

= 682+558

= 1240

So, there are 1240 students at the school.

Answer:

h = 41.25 foot

Step-by-step explanation:

Given that,

Height of a street light = 7.5 feet

It casts a 3-foot-long shadow.

A nearby flagpole casts a 16.5 foot long shadow. We need to find the height of the flag pole. Let the height be h. It can be calculated as :

[tex]\dfrac{\text{height of street light}}{\text{height of shadow of street light}}=\dfrac{\text{height of flagpole}}{\text{height of shadow of the flag pole}}\\\\\dfrac{7.5}{3}=\dfrac{h}{16.5}\\\\h=\dfrac{7.5\times 16.5}{3}\\\\h=41.25\ foot[/tex]

So, the height of the flag pole is equal to 41.25 foot.

The height of the flag pole is 41.25 feet tall.

Word problems in mathematics are methods used to solve real-life cases. They usually follow a logical approach with the use of arithmetic operations when solving them.

From the parameters given:

Let the height of the flag pole be = x

∴

To determine the height of the flag pole, we have:

[tex]\mathbf{x = \dfrac{7.5 feet \ tall \times 16.5 \ foot \ long} {3 \ foot \ long} }[/tex]

x = 41.25 feet tall

Step-by-step explanation:

The longest measure from the given measures is 30 kilometers.

A no. of measurement values are given in the question.

We have to find out which is the longest from them.

What is the meaning of unit conversion ?

A unit conversion is done to express the same property as a different unit of measurement.

As per the question ;

Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.

Let's check which is the longest by converting them all in same units say centimeters.

So ;

a) 90 centimeters

= 90 centimeters

b) 40 meters

= 40 × 100 centimeters

= 4000 centimeters

c) 30 kilometers

= 30 × 1000 meters

= 30000 × 100 centimeters

= 3000000 centimeters

d) 10 meters

= 10 × 100

= 1000 centimeters

e) 40 millimeters

=  40 / 10 centimeters

= 4 centimeters

So ; the longest is 30 kilometers.

Thus , the longest measure from the given measures is 30 kilometers.
