HELP!

Step-by-step explanation:

The formula for exponetial equation decay is

[tex]y = a(b) {}^{x} [/tex]

where a is the initial value and b is the decay factor.

A will be 56 since that our initial value.

b will be 0.9 since we are constantly decaying by 0.9.

so our equation is

[tex]y = 56(0.9) {}^{x} [/tex]

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

1 ft by 8 ft,

two opposite faces with dimensions

1 ft by 4 ft,

and two opposite faces with dimensions

4 ft by 8 ft.

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2

(7x - 23)° + (11x + 23)° = 180°

7x - 23° + 11x + 23° = 180°

18x = 180° / : 18

x = 10°

Answer:

they're all wrong, it should be [3,4,7,9]

Answer:

2x + 3y = 15

x + y = 6 --> 2x + 2y = 12

By elimination method

2x + 3y = 15

-2 - 2y= -12

y = 3

x + y = 6

--> x = 3

uhmm this is probably so wrong

Answer: The number is 0

Step-by-step explanation:

8 = 7x + 8

Then we solve it:

8 = 7x + 8

8 - 8 = 7x

0 = 7x

0 ÷ 7 = x

x = 0

hope this helps have a nice day

Answer: 8

Step-by-step explanation:

Answer: 8 pizzas.

Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

Answer:

Folow the steps to learn what transformations were determined.

Step-by-step explanation:

First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.

X    Y

2    4

1     1

0    0

-1     1

-2    4

Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.

Vertical Shifts:

f(x) + c moves up,

f(x) - c moves down.

Horizontal Shifts:

f(x + c) moves left,

f(x - c) moves right.

The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Answer:

x=-3

Step-by-step explanation:

[tex]-15x=45\\-x=3\\x=-3[/tex]

Answer:

368 milliliters.

Step-by-step explanation:

Compound A + Compound B = 1 drug

4 + 7 = 1 drug

11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

Multiply the compounds by the amount of drugs, e.g.

4 x 92 = 368 ( Compound A )

7 x 92 = 644 ( Compound B )

368 + 644 = 1012

368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

Answer:

l = 6 cm

Step-by-step explanation:

Given that,

The volume of a cuboid, V = 384 cm³

The base and height are 8 cm

We need to find the length of the cuboid. The formula for the volume of a cylinder is given by :

[tex]V=l\times b\times h\\\\l=\dfrac{V}{bh}\\\\l=\dfrac{384}{8\times 8}\\\\l=6\ cm[/tex]

So, the length of the cuboid is 6 cm.

Answer:

x=20

Step-by-step explanation:

ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540

so we setup an equation which would be

7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x

step 1 combine like terms

7x+4x=11x

11x+4x=15x

15x+5x=20x

20x+6x=26x

5+10=15

15-5=10

10+10=20

now we have

20+26x=540

step 2 subtract each side by 20

20-20 cancels out

540-20=520

now we have 26x=540

the final step is to divide each side by 26

26/26 cancels out

540/26=20

x=20

hope this helps :D

Answer:

(3,-2)

Step-by-step explanation:

The solution is, there is  no solution to the system.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Given the equation y=-2x+1

and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect.

Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel.

To have this result, we must have that they have the same slope but different y intercept.

That is take m = -2 and b any value different to +1. For example, the b = 6.

So, y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.

Step-by-step explanation:

i took the test

Answer:

an answer is precise when it is an exact number like 10, 2, or 123.

An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11

Answer:

Step-by-step explanation:

Well, since 50,000 dollars is in the 5% tax range, then we would have to find 5% of 50,000 dollars. So, we would have:

[tex]50,000\cdot5\%=50,000\cdot\frac{1}{20}=\frac{50,000}{20}=2500.[/tex]

HOPE IT HELPS.

Answer:

the answers B and D are correct

Answer:

B & D

Step-by-step explanation:

It can-t be A, because that would mean 20², which equals 400, would equal 20.

B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.

C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.

D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.

E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong

Answer:

x=15 degrees

Step-by-step explanation:

You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.
