Answer:

A, 210

Step-by-step explanation:

7 x 5 = 35 divided by 2 = 17.5 x 12 = 210

Formula of a triangle:

Bh x 1/2 (basically dividing by 2)

Your base is the length on the bottom your height is that line in the middle of the triangle. Multiply those then divide by two to get the area always. But since its long and its a prism you have to multiply by 12.

Volume will always have the unit 3 in it and the measuring unit will depend on what is says for example in this problem its inches so its inches cubed (3).

Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to H
MrRissso [65]

<span>g(x) = x3 – x2 – 4x + 4 </span>

<span>You can find the zeroes by factoring the equation. x<span>2  </span>(x - 1) - 4(x - 1) = 0 </span>

<span>(x2 - 4) (x - 1) = 0 </span>

(x + 2) (x - 2) (x - 1) = 0

x = 2, -2, and 1

The following are the key features of g(x):

g'(x) yields the slope

g''(x) yields the concavity

g'(x) = 0 provides the critical points

<span>g''(x) = 0 provides the point of inflection</span>

serious [3.7K]

Answer:

75\text{ miles, }28\text{ miles}

Step-by-step explanation:

GIVEN: Emma started biking to the coffee shop traveling 15 \text{mph}, after some time the bike got a flat so Emma walked the rest of the way, traveling 7 \text{mph} If the total trip to the coffee shop took 9 \text{hours} and it was 103 \text{miles} away.

TO FIND: how long did Emma travel at each speed.

SOLUTION:

Let the distance traveled by Emma through bike is \text{x}

Total time taken when traveled by bike =\frac{\text{x}}{15}

Distance traveled through feet =103-\text{x}

Total time taken when traveled by feet =\frac{103-\text{x}}{7}

Now,

Total time taken =9\text{hours}

\frac{\text{x}}{15}+\frac{103-\text{x}}{7}=9

8\text{x}=600

\text{x}=75

Distance traveled through feet =103-75=28\text{miles}

Hence distance traveled using bike is 75\text{miles} and by feet is 28\text{miles}
