X = [tex]\frac{my}{m} = \frac{28}{19}[/tex]

Y = [tex]\frac{mx}{m} = \frac{872}{95}[/tex]

Step-by-step explanation:

y = x and x = 0

parabola ; y = 20 - x^2

attached below is the detailed solution

M = [tex]\frac{152}{3}[/tex]б

Mx =  [tex]\frac{6976}{15}[/tex]б

My = [tex]\frac{224}{3}[/tex]б

X = [tex]\frac{my}{m} = \frac{28}{19}[/tex]

Y = [tex]\frac{mx}{m} = \frac{872}{95}[/tex]

jumping jacks can you do in 5 minutes?
2 149 jumping jacks
c220 jumping jacks
b. 239 jumping jacks
d 8jumping jacks

Answers

Answer:

We can do 220 jumping jacks in 5 minutes.

Step-by-step explanation:

We are given the function:

[tex]j(x) =44x[/tex]

Note: Considering there is typing mistake and the function is: j(x)=4x

where x is minutes

We need to find How many  jumping jacks can you do in 5 minutes.

So, here x=5

Now putting value of x in the given function

[tex]j(x) = 44x\\Put \ x=5\\j(5)=44(5)\\j(5)=220[/tex]

So, we can do 220 jumping jacks in 5 minutes.

Caitlin drew a scale drawing of the community park in her town. The actual
long.


What scale did Caitlin use to draw the park?
o 1 inch equals 4 feet
4 inches equal 4 feet
o 1 inch equals foot
4 inches equal 1 foot

Answers

Answer: 1 inch equals 4 feet

Step-by-step explanation:

By an online search, I´ve found that:

The park is 48 ft long.

Caitlin´s drawing is 12 inches long.

To find how much each inch represents, we need to take the quotient between those lengths:

48ft/12in = 4ft/in.

We also can write this amount as:

4 feet per inch.

This means that each inch represents 4 feets.

Then the correct option is the first one:  1 inch equals 4 feet

The football coach threw a football from a platform to his
quarterback below. The height of the football, h, at time t seconds is modeled by the equation h(t) = -16t^2 + 28t + 15.
1. What is the maximum height of the ball?
2. If the quarterback caught the ball at a height of 6 feet, how many seconds was the ball in the air?
3. Give the domain and range of the function.

Answers

Answer:

1)27.25 feet

2)-0.2774,2.027

3)Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

Step-by-step explanation:

The height of the football, h, at time t seconds is modeled by the equation [tex]h(t) = -16t^2 + 28t + 15[/tex]

General quadratic equation : [tex]ax^2=bx+c=0[/tex]

1) Maximum height will be at [tex]\frac{-b}{2a}=\frac{-28}{2(-16)}=\frac{7}{8}[/tex]

To find maximum height Substitute [tex]t = \frac{7}{8}[/tex] in the given equation

[tex]h(t)=-16(\frac{7}{8})^2+28(\frac{7}{8})+15\\h(t)=27.25 feet[/tex]

2)

Substitute h(t)=6

So, [tex]-16t^2+28t+15=6[/tex]

[tex]-16t^2+28t+9=0\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-28\pm \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=\frac{-28+ \sqrt{28^2-4(-16)(9)}}{2(-16)},\frac{-28- \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=-0.2774,2.027[/tex]

Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

Answers

Answer:

(8-n=4)/4 click brainliest please and click thanks

Step-by-step explanation:

The mathematical expression which represents the phrase four equals the difference between eight and a number and the result is divided by four is (4 = 8 - x)/4.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

Difference of 8 and a number x = 8 - x

4 equal to 8 - x

4 = 8 - x

Now,

The result is divided by 4

Therefore,(4 = 8 - x)/4

Hence "The mathematical expression which represents the phrase four equals the difference between eight and a number and the result is divided by four is (4 = 8 - x)/4".

Answer:

Step-by-step explanation:

The equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.

What is a complex number?

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

= 4+i

Multiply it by 1/2

[tex]= \rm \dfrac{1}{2}(4+i)\\\\\rm =2+ \dfrac{1}{2}i[/tex]

[tex]\rm \dfrac{1}{2}(4+i) =2+ \dfrac{1}{2}i[/tex]

Thus, the equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.
