How to solve the exponent ​

Answer:

W=4 l=16

Step-by-step explanation:

Let w = width

Let l = length

Since the length is 4 times the width, l=4w

Perimeter of rectangle = 2l + 2w

= 2(4w)+2w

=10w

The perimeter of the rectangle =40, so

40=10w and w=4

Plug w into the length equation : l=4w=4(4)=16

Answer:

  see the attachments for the graph(s)

Step-by-step explanation:

1) The point at (3, 6) is on the vertical line that is halfway between the zeros at x=-3 and x=9, so it represents the vertex of the function. That knowledge, with any of the other points, lets you write the vertex form of the equation.

  y = a(x -3)^2 +6

Using the point (0, 4.5), we can find the value of 'a':

  4.5 = a(0 -3)^2 +6

  -1.5 = 9a

  -1.5/9 = a = -1/6

So, the vertex form of the equation is ...

  y = -1/6(x -3)^2 +6

A graph of this is shown in the attachment.

__

2) Now that we know the leading coefficient is -1/6, we can write the equation in "intercept form" (factored form) as ...

  y = -1/6(x +3)(x -9)

In this form, each zero (p) gives rise to a factor (x-p).

The second attachment shows the graph of this.

__

3) We can also write the equation in standard form, by expanding the one in (2) above:

  y = -1/6(x^2 -6x -27)

  y = -1/6x^2 +x +9/2

The third attachment shows the graph of this.

Answer:

-57

Step-by-step explanation:

B- brackets

O- of

M- multiplication

A- addition

S - subtraction

-3[1+2(4+5)]

first solve what is in the brackets

(4+5) = 9

place 9 in the brackets

-3[1+2(9)]

now multiply the 2 and 9

2*9 = 18

-3[1+18)]

1+ 18 = 19

now multiply the (-3) with 19

= -57

Answer:

-57

Step-by-step explanation:

To solve this problem, you need to use the acronym PEMDAS.

P = parenthesis (if there is any in the expression) or brackets

E = exponents (if there is any in the expression)

D/M = Divide or Multiply or both

A/S = Add or Subtract or both

In the problem, you need to simplify the parentheses ( ) inside the brackets first. For example: -3 [1 + 2(4 + 5)]. That will equal to -3 [1 + 2(9)]. Next, you can solve the brackets now. Since there is both a addition and multiplication problem inside these brackets, you must do the multiplying first. For example,

-3 [1 + 2(9)]. That equals to -3 [ 1 + 18}. Next, do the addition inside of the brackets and then multiply that answer to -3. For example, -3 [1 + 18}. That equals to -3 [19]. Do the multiplication by a calculator or by hand. if you are doing by hand, ignore the signs of the numbers until the very end.

If doing by hand, first you need to multiply 9 by the 3 to get 27. Keep the 7 and borrow a 2 on top of the ones places which is 1. Multiply the 1 by the 3 which gets 3 and add 2 to the 3 to get 5. You got the 2 from multiplying 9 by 3 which is 27. Since the 3 in this problem is negative, that will leave your answer with a negative number. Since a negative times a postive will always be negative. If the number of negatives is odd in the problem, then it will a negative answer. If the number of negatives is even, the answer will be positive. Same thing applies to division. You get -57 as your answer.

Answer:

The rocket will hit the ground at 64.2 seconds.

Step-by-step explanation:

The time at which the rocket will hit the ground can be calculated using the following equation:

[tex] Y_{f} = Y_{0} + V_{0}y*t - \frac{1}{2}gt^{2} [/tex]

Where:

[tex]Y_{f}[/tex]: is the final height = 0

[tex]Y_{0}[/tex]: is the initial height = 3 ft

[tex]V_{0}[/tex]: is the initial speed = 315 ft/s

t: is the time =?

g: is the gravity = 9.81 m/s²

[tex] 3 + 315*t - \frac{1}{2}9.81*t^{2} = 0 [/tex]        

Solving the above quadratic equation for t, we have the following values:

t₁ = -0.0095 s

t₂ = 64.2 s

Taking the positive value, we have that the rocket will hit the ground at 64.2 seconds.

I hope it helps you!

Answer:

D) $9.06

correct on edge :)

The total amount of money saved from purchasing the plants at a marked down price is  $9.06

The first step is to determine the original price of one potted begonias: $6.57 / (1 - 0.27)  = $9

The first step is to determine the original price of one tomato seedling: $2.60 / ( 1 - 0.35)  = $4

The amount saved on potted begonias = ($9 - 6.57) x 2 = $4.86

The amount saved on tomato seedlings = (4 - 2.60) x 3 = $4.20

Total amount = $9.06

Answer:

The number of apples in the 12th bag is 9

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum{x_i}}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the value of n=12 and the mean number of apples in each bag (8), thus:

[tex]\displaystyle 8=\frac{\sum{x_i}}{12}[/tex]

Multiply by 12

[tex]\sum{x_i}=96[/tex]

This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:

[tex]6*1+7*4+8*2+9*3+10*1=87[/tex]

Note the sum should be 96, so the 12th bag must have 96-87=9 apples

The number of apples in the 12th bag is 9

Answer:

(-12,0)                                                   (0,0)                                  (x,y)

y is zero since P is at the origin with coordinate(0,0)

Answer:

5 units

Step-by-step explanation:

Here, we want to find the distance CP

the distance from the center of the circle to the circumference is referred to as radius.

Hence CP is the radius of the circle

Also CN is another radius and also CK is another radius

Thus, mathematically; CN = CK

This means that;

x^2 -20 = 3x -10

x^2 -20 -3x + 10 = 0

x^2 -3x -10 = 0

x^2 -5x + 2x -10 = 0

x(x-5) + 2(x-5) = 0

(x-5)(x+2) = 0

x = 5 or -2

To get CP , we can substitute for x in any of the given expressions

Let’s use 3x-10

Using x = 5

3(5) -10 = 15-10 = 5

Using x = -2

3(-2) -10 = -6-10 = -16

But since length cannot be negative , 5 units is our answer
