Another plan to secure the roller coaster involves using a cable and strut. using the center of the half-circle as the origin, the concrete strut can be modeled by the equation y=sqrt(2x+8) and the mathematical model for the cable is y=x-8.the cable and the strut will intersect.
6. graph the cable and the strut on the model of the roller coaster using the graphing calculator. take a screenshot of your graph and paste the image below. (5 points)
7. algebraically find the point where the cable and the strut intersect. interpret your answer. (10points)

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

it's the only multiple of both and the least

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
