Answers

Answer 1

Answer:

[tex]134.56[/tex]

Step-by-step explanation:

Break 11.6 into addenda.

[tex](11 + 0.6)[/tex]

Apply the binomial expansion method.

[tex](11 + 0.6)(11 + 0.6)[/tex]

[tex]11 {}^{2} = 121[/tex]

[tex]2(11)(0.6) = 13.2[/tex]

[tex]0.6 {}^{2} = 0.36[/tex]

Add them all up and you get.

the sum of 2 numbers is 56.twice the smaller number exceeds one-half the larger number by 22.find the numbers

  20, 36

Step-by-step explanation:

Let x and y represent the smaller and larger numbers, respectively. The given relations let us write two equations:

  x + y = 56 . . . . . . the sum of the two numbers is 56

  2x -y/2 = 22 . . . . twice the smaller exceeds half the larger by 22

We can solve this by multiplying the second equation by 2 and adding the first.

  2(2x -y/2) +(x +y) = 2(22) +56

  5x = 100 . . . . . . simplify

  x = 20

  y = 56 -20 = 36

The two numbers are 20 and 36.

Answer and Step-by-step explanation:

First, you find the x-value of f(x) on the graph, and find the corresponding y-value.

On the graph, we see that when we go to the x-value of -7, we are at a y-value of 0. Now, we plug this in to the g(x) function and look for the y-value on the g(x) graph.

When 0 is plugged in for x in g(x), we get the y-value to be 5.

This means that the value of g(f(-7)) is 5.

An isosceles triangle has an angle that measures 116°. Which other angles could be in that isosceles triangle? Choose all that apply.

Answers

Answer:

Step-by-step explanation:

since we know that triangles have 180° we know that 116° is two much if it's doubled  2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116  is the left over amount that is even divided into the last two angles so   180 - 116 = 64 / 2 = 32°  so the triangle is made up of  116 + 32 + 32 degree angles

Answer:

y = ½x + 8

Step-by-step explanation:

✔️First, find the slope (m) using any two given pairs of values, say (0, 8) and (2, 9):

Slope (m) = change in y/change in x

Slope (m) = (9 - 8)/(2 - 0)

Slope (m) = 1/2

m = ½

✔️Find the y-intercept (b):

The y-inteeceot of the function would be the value of y when x = 0.

Form the table, when x = 0, y = 8. Therefore:

y-intercept (b) = 8

✔️To write the equation of the function, substitute m = ½ and b = 8 into y = mx + b.

Thus:

y = ½x + 8
