and g(x) = (x + 5)^2. Options: -5/2 , -7/2 , 37/4 , 7/3

Answers

Answer:

7/3

Step-by-step explanation:

f(x) =7/(x+2)

g(x) = (x + 5)^2

f(g(-4))=

First find g(-4)

g(-4) = (-4+5)^2

        =(1)^2 =1

Then find f(1)

f(1)= 7/(1+2)

Please help! I don’t understand it my teacher wasn’t here..

Answers

Let's solve for b first.

Since b and 147 are opposite, b is also equal to 147 degrees.

b=147

Since c and 147 are supplementary angles, they sum to 180 degrees.

c+147 = 180

Subtract 147 from both sides

c = 33

Triangle ABC is a right triangle. What is the length of AC?

Answers

Answer:

AC = [tex]\sqrt{58}[/tex]

Step-by-step explanation:

Calculate AC using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )

AC = [tex]\sqrt{(3-0)^2+(5-(-2)})^2[/tex]

     = [tex]\sqrt{3^2+(5+2)^2}[/tex]

    = [tex]\sqrt{9+7^2}[/tex]

    = [tex]\sqrt{9+49}[/tex]

    = [tex]\sqrt{58}[/tex]

What is the probability that one randomly selected physician is a man or is 35-44 years old

Answers

Answer:

28%

Step-by-step explanation:

Joyfoyfoyfyfrugifgpuyg

Based on this table, the probability that the physician is a man is 78%
Now, if the physician is a man and 35-44 years old, he’s already included in that 78%, so we only need to now consider the possibility that they physician is female and 35-44 years old: 8%.

So the total probability is 78% (male) + 8% (female and 35-44) = 80%

This can also be found by adding up all the individual probabilities in your table:

Find an equation for the perpendicular bisector of the line segment whose endpoints are (-1,-7)(−1,−7) and (9,1)(9,1).

He dhjxbaandndbd cmnd dnjdjdjsjjd

Answer:

y = -5/4 - 31/5

Step-by-step explanation:

A: (-1,-7) and B: (9,1)

Slope: (-7-1)/(-1-9) = -8/-10 = 4/5

Slope: 4/5. Point (9,1)

y-1 = 4/5 (x-9)

y-1 = 4/5x - 36/5

y = 4/5x - 36/5 + 1

y = 4/5x - 31/5

Perpendicular bisector = Y = - 5/4x - 31/5

Find the slope-intercept form of the equation of each of the following lines.
Passes through (6, 4) and has slope =1/2

Answers

Answer:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is [tex]\displaystyle\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+b[/tex]

Now, to solve for the y-intercept, plug in the point (6,4) and solve for b:

[tex]4=\displaystyle\frac{1}{2}(6)+b\\\\4=3+b\\b=1[/tex]

Therefore, the y-intercept of the line is 1. Plug this back into [tex]y=\displaystyle\frac{1}{2}x+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

A merchant has coffee worth $40 a pound that she wishes to mix
with 60 pounds of coffee worth $90 a pound to get a mixture that
can be sold for $70 a pound. How many pounds of the S40 coffee
should be used?
O 20 pounds
O 40 pounds
100 pounds
O 50 pounds

Answers

Answer:

Step-by-step explanation:

let x = the number of pounds of cheaper coffee.

Since the merchant is mixing this with more expensive coffee, then

x + 60 = the number of pounds of medium priced mixed coffee.

The equation is gotten from this

+  =  

(x)($40)  + (60)($90)   = (x + 60)($70) or

            40x + 5400 = 70(x + 60)

Solve that equation and get x = 40

Answer: 40 pounds of $40 coffee.
