Answer:

1 5/24 + 7 22/24 = 8 27/24

Step-by-step explanation:

No change is required to the fraction on the first line:

1 5/24 = 1 5/24

The fraction on the second line can be multiplied by 2/2 to make its denominator 24.

7 11/12 = 7 22/24

The fraction on the third line is the sum of the fractions on the other two lines. It is an improper fraction. We know this because the integer portion of the sum is shown as 8, not 9, as it would be if the fraction were reduced.

5/24 +22/24 = 27/24

Then the sum is ...

1 5/24 +7 22/24 = 8 27/24

_____

If the fraction on the final line were reduced, the sum would be 9 3/24 = 9 1/8.

Or Simplify. Express your answer as a single term using exponents. 303*9x303*9

dmitriy555 [2]

${303}^{9} \times {303}^{9} \\ = {303}^{9 + 9} \\ = {303}^{18}$

Answer:

${303}^{18}$

Hope you could get an idea from here.

Write the word sentence as an inequality, 3 less than a number t is at most 7

AlexFokin [52]

"3 less than a number t is at most 7"

"3 less than a number t" --> $t - 3$
"is at most" --> $\leq$
"7" --> $7$

put this together and we get:
$t - 3 \leq 7$

90 POINTS I need help ASAP on everything but part A (WILL GIVE BRAINLIEST) Roller Coaster Crew Ray and Kelsey have summer intern

maxonik [38]

Answer:

Part A) Kesley is correct

Part B) g'(x)=3x2-2x-4

Part C) Graph attached

Part D) Explained

Step-by-step explanation:

Part A)

Kelsey is correct because no. of 0s in a 3rd degree polynomial be 3. which means the no. of intercepts will be 3. Thus Ray is incorrect as no. of 0s and x-intercept are similar thing.

Further a graph is attached of g(x) = x3 − x2 − 4x + 4 to describe the key features of g(x), including the end behavior. We can see that there are 3 x-intercepts at (2,0), (1,0) and (-2,0) which validates the point of Kelsey that the function can have as many as 3 zeros only because it is 3rd degree polynomial.

Part B)

As the second part of the new coaster is a parabola. To create a unique parabola in the pattern f(x) = ax2 + bx + c

finding derivative of g(x) picked in Part A) i.e.

g(x) = x3 − x2 − 4x + 4

g'(x)=3x2-2x-4

Graph of above is also attache.

From the graph we can see that its downwards directed parabola having vertex at (0.33, -4.33)

x-intercept at -0.87 and 1.53

y-intercept at (0,-4)

The axis of symmetry equation is a vertical line around which the parabola is symmetric is given by equation of a vertical line that passes through the vertex i.e. x=0.33

Part C)

Graph 3 is also attached.

Part D)

For a 15 seconds ad campaign, following features can be included:

Roller coaster that have a three rise

two sharp dips

the 2nd dip goes more deeper than the first one!
