4/5 of the senior class went to prom if 324 seniors went to prom how many are there in the senior class
Sedbober [7]

Answer:

405

Step-by-step explanation:

324 seniors is 4/5 of all seniors. To find how many 5/5 of the seniors is, we find 1/5 and multiply it by 5. Since 4/5 is 4 times 1/5, divide 324 by 4. The answer is 81, which is 1/5 of the seniors. Multiply 81 by 5 to get all 5/5. 81 * 5 is 405

Which of the following is not a zero of f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0
Alenkinab [10]

Answer:

Only 2 and -5 are roots. Any other number is not a root.

Step-by-step explanation:

The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.

The f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into

f(x) = (x -2)(x-2)(x+5)(x-2) = 0.

Set each factor equal to 0 and solve.

x - 2 = 0 so x = 2. This repeats twice.

x + 5 = 0 so x = -5.

So the zeros are 2, -5.
