Plzzz help!! just atleast look at my question!! plzz I really need help!

Answer:

Step-by-step explanation:

k= 100- 4n

what is n if k is 99 ​

-------

99 = 100 - 4n

4n = 100 - 99

4n = 1

n = 1/4 or 0.25

--------------check

99 = 100 - 4 × 1/4

99 = 100 - 1

99 = 99

the answer is good

Answer:

y= 6/7

Step-by-step explanation:

0.5y + 7 = 5( 0.2 + 1.5y )

Get rid of the brackets first

0.5y + 7 = 1 + 7.5y

Move the like terms

0.5y + 7 - 7.5y = 1

0.5y - 7.5y = 1 - 7

Collect the like terms

-7y = -6

Divide both sides by -7 to get y on its own

y= -6/-7

A negative number divided by a negative number gives a positive number so

y = 6/7

Answer:

y=6/7  or 0.857 aprox.(0.86)

Step-by-step explanation:

[tex]0.5y+7=5(0.2+1.5y)[/tex]

[tex]0.5y+7=1+7.5y[/tex]

[tex]7.5y-0.5y=7-1[/tex]

[tex]7y=6[/tex]

[tex]y=6/7= 0.857[/tex]

Step-by-step explanation:

Using the information given above, the sampling distribution of the sample proportion of 100-ohm gold-band is 2.

The sampling distribution of the sample proportion can be calculated thus:

Distribution of sample proportion = (100 × 0.02) = 2

Therefore, there is a probability that only 2 of the samples will have resistances exceeding 105 ohms.

After the increase in the dimensions of the sign, the effect on the area of the sign is that the new area is 8 times larger than the initial area.

The sign has the shape of a rectangle. A rectangle has four sides. The opposite sides are equal in length.

The area of a rectangle = length x width.

Jimmy is making the sign bigger by increasing the size of the length and width. Let's imagine that the width is 8cm and the length is 10cm.

The initial area of the sign = 10 x 8 = 80 cm

After the increase in the dimensions, the length is are 40cm and 16cm for the width.

New area = 40 x 16 = 640

Number of times the new area is greater than the initial area = 640 / 80 = 8 times larger

Answer:

Approximately 13.41

Step-by-step explanation:

First do square root of each, which is finding what number multiplies by its self to get the number.

For example: The square root of 80 is approximately 8.94, and the square root of 20 is approximately 4.47.

So: 8.94 + 4.47 = 13.41 (Add normally, but remember to put the decimal in the right place).

The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².

Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).

Since, g(x) is an upside down function of f(x), g(x) = -f(x).

If we multiply a function by a coefficient, the graph of the function will be stretched.

A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.

A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.

Since, g(x) is clearly a stretched transformation of f(x), c < 1.

The possible function g(x) = -0.5x².

Answer:

A) 7.5 seconds

Step-by-step explanation:

Height of the ground is zero

-16t^2 + 120t = 0

Divide both sides by 16

-t^2 + 7.5t = 0

Factor out t

t(-t + 7.5) = 0

From the zero product rule

t = {0, 7.5}

0 would be time of launch

7.5 is time back to the ground

When it says y varies directly with x it just means that y and x are proportional/equal to each other. The constant of variation and the constant of proportionality are the same thing just different way of saying it so they can confuse you and make your life miserable. Since y and x are proportional to each other and the constant of proportionalty is -5 to make an equation that represents a line you use the formula y=mx+b. That is the slope of the line. With that formula let's first plus in the x so we have y=m2+b. The formula for direct variation is y=kx as well that's good to know and it's good to memorize all these formulas. Math becaomes easier when you have the process down pat and you just need to plug numbers into different equations, expressions, and scenarios. Do m = [y1 - y2] / [x1 - x2] and you'll get the answer.

It's the last option "24 + 49i + 15i^2"

Step-by-step explanation:

To solve you must do FOIL, (First, Outer, Inner, Last). To do this, you must do:

8 × 3 = 24 , 8 × 5i = 40i , 3i × 3 = 9i , and

3i × 5i = 15i^2 .

Don't forget to combine like terms.

Altogether: 24 + 49i + 15i^2 .
