Mathematics

fgiga [73]3 years ago
8 0

The average is 105.5. To find the average, you have to add up all numbers, 63+148=211. Now you have to divide by how many numbers there are,               211÷2=105.5

A diamond ring increases in value at a rate of 5% per year. If the ring was purchased for $1200, which equation would calculate
Margarita [4]

Answer:

A - y = 1200(1+.05)^30

Step-by-step explanation:

In this case, you need to calculate the future value and the formula to calculate that is:

FV=PV*(1+r)^n

FV=future value

PV=present value

r=rate

n=number of periods of time

The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:

FV=1200*(1+0.05)^30

According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Error Analysis: Kayla said the remainder of x^3+ 2x^2 -4x + 6 divided by
andrezito [222]

9514 1404 393

Answer:

  C) No, Kayla is not correct, because the remainder is -49 not 149

Step-by-step explanation:

The remainder from division by x+5 can be found by evaluating the polynomial at x=-5, the value of x that makes the divisor zero.

Evaluation is often easier when the function is written in Horner form.

  ((x +2)x -4)x +6

For x=-5, this is ...

  ((-5 +2)(-5) -4)(-5) +6 = (-3(-5) -4)(-5) +6 = 11(-5) +6 = -49

Kayla is not correct; the remainder is -49.

Help, i suck at graphs. I don’t understand them not one bit.
Daniel [21]

Answer:

THE ANSWER IS A

Step-by-step explanation:

Composition of a function is done by substituting one function into another function. For example, f [g (x)] is the composite function of f (x) and g (x). The composite function f [g (x)] is read as “f of g of x”. The function g (x) is called an inner function and the function f (x) is called an outer function.

The notation used for the composition of functions looks like this, (f g)(x). ... (f g)(x) and(g f)(x) are often different because in the composite(f g)(x), f(x) is the outside function and g(x) is the inside function. Whereas in the composite(g f)(x), g(x) is the outside function and f(x) is the inside function.
