!!!!!!HELP!!!!!! WORTH 22 POINTS. OG and OH divide straight angle FOJ into three angles whose measures are in the ratio 4: 3: 2. Find the measurement of angle FOG

(all the mentions to FOJ, FOG, GOH, HOJ refer to the angles)

FOJ = 180

FOJ = FOG + GOH + HOJ [make the drawing to see this clearly]

FOG = 2 (HOJ)

GOH = 3 (HOJ)/2

HOJ = HOJ

2 (HOJ) + 3(HOJ)/2 + HOJ = 180

4.5 HOJ = 180

HOJ = 180/4.5

HOJ = 40

FOG = 2(40) = 80

Answer: angle FOG measures 80 degrees.

Terri is analyzing a circle, y2 + x2 = 36, and a linear function g(x). Will they intersect? y2 + x2 = 36 g(x) graph of the function y squared plus x squared equals 36 x g(x) −4 −4 −2 −2 2 2 Yes, at positive x-coordinates or zero Yes, at negative x-coordinates or zero Yes, at negative and positive x-coordinates or zero No, they will not intersect

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Step-by-step explanation:

The equation of circle is given as:

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

x         g(x)

−4       −4

−2        −2

2          2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Your emergency fund savings account has \$2,400 and you put the remainder of your monthly income into the emergency fund each month. How much more money would you have to save each month to complete your emergency fund in 12 months? a. \$300 per month b. \$150 per month c. \$75 per month d. \$60 per month

Your end goal is to have \$6000 total in 12 months. since you have \$2400 already you can subtract that from 6000 leaving you with \$3600 over the course of 12 months. since you already put \$150 in a month over the course of 12 months you would have \$1800 which is only half of the goal of \$3600. in order for you to put in \$3600 you would have to put an additional 150 in your savings along with your regular 150 making the answer b.

Each term will be 5 less than the previous term since the formula says to subtract 5.

3, –2, –7, –12, ... is the correct sequence.

f(1) would be 3
f(2) = f(1 + 1) = f(1) - 5 = 3 - 5 = -2
f(3) = f(2 + 1) = f(2) - 5 = -2 - 5 = -7
f(4) = f(3 + 1) = f(3) - 5 = -7 - 5 = -12
