I need help Evaluate functions from their graph

Mathematics
1 answer:
andreev551 [17]3 years ago
6 0

Answer:

g(7)=4

Step-by-step explanation:

We look for where x=7. The way you find the answer is first, find the point (0, 7). Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).

Using this method here, we see that g(7) intersects our line at (7, 4), so g(7)=4.

HELP! What is angle 5? (PICTURE INCLUDED)
lapo4ka [179]

Answer:

Angle 5 = 122

Step-by-step explanation:

Assume EB and AD intersect each other at point C

As this is the circle, four points A,B,D,E are all on the circle, so that we have:

+) m∠EBD = 1/2 measure of arc ED (small arc)

=> m∠EBD = 1/2 . 66 = 33 degree

=> m∠CBD = 33

+) m∠ADB = 1/2 measure of arc AB (small arc)

=>m∠ADB = 1/2 . 50 = 25 degree

=>m∠CDB = 25 degree

In the triangle CDB, we have total measure of three internal angles is 180 degree

=> Angle 5 + m∠CDB + m∠CBD = 180

=> Angle 5 + 25 + 33 = 180

=> Angle 5 = 180 -25 - 33 = 122 degree

There are 158 students registered for American History classes. There are twice as many students registered in second period as
Margarita [4]

There are 28 students in first period and 56 students in sceond period and 74 students in third period

<em><u>Solution:</u></em>

Let the number of students in first period be "x"

Let the number of students in second period be "y"

Let the number of students in third period be "z"

<em><u>There are 158 students registered for American History classes.</u></em>

Therefore,

x + y + z = 158 ---------- eqn 1

<em><u>There are twice as many students registered in second period as first period</u></em>

number of students in second period = twice of number of students in first period

y = 2x ------- eqn 2

<em><u>There are 10 less than three times as many students in third period as in first period</u></em>

number of students in third period = 3 times number of students in first period - 10

z = 3x - 10 ------ eqn 3

<em><u>Substitute eqn 2 and eqn 3 in eqn 1</u></em>

x + 2x + 3x - 10 = 158

6x = 168

<h3>x = 28</h3>

<em><u>Substitute x = 28 in eqn 2</u></em>

y = 2(28)

<h3>y = 56</h3>

<em><u>Substitute x = 28 in eqn 3</u></em>

z = 3(28) - 10

z = 84 - 10

<h3>z = 74</h3>

Thus there are 28 students in first period and 56 students in sceond period and 74 students in third period
