Do the functions have the same concavity?
Vesna [10]

Answer:

Step-by-step explanation:

Function f is graphed. The positive x-axis contains point c. The graph consists of an N-shaped curve. The curve starts in quadrant 3, moves upward concave down to a point in quadrant 1, moves downward concave down to point c in quadrant 1, continues downward concave up to a point in quadrant 4, moves upward concave up and ends in quadrant 1. The curve is purple to the left of point c, where it is concave down, and is green to the right of point c, where it is concave up.

Notice how fff is \purpleC{\text{concave down}}concave downstart color #aa87ff, start text, c, o, n, c, a, v, e, space, d, o, w, n, end text, end color #aa87ff to the left of x=cx=cx, equals, c and \greenD{\text{concave up}}concave upstart color #1fab54, start text, c, o, n, c, a, v, e, space, u, p, end text, end color #1fab54 to the right of x=cx=cx, equals, c.

f, start superscript, prime, prime, end superscript.

Function f double prime is graphed. The x-axis goes from negative 8 to 8. The graph consists of a wave-shaped curve. The curve starts at (negative 8, 0), moves downward concave up to (negative 5, negative 5), moves upward concave up to (negative 2, 0), continues upward concave down t

You borrow $30,000 to buy a new car. The simple interest
bagirrra123 [75]

Answer:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, the answer is $3,000. If you want to calculate the interest on $30000 at 5% interest per year after 5 years,  the answer is $7500.

Step-by-step explanation:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 2% per year, or in decimal form, 2/100=0.02.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.02 × 5 to get that the interest is: $3000.00

Now, if you want to calculate the interest on $30000 at 5% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 5% per year, or in decimal form, 5/100=0.05.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.05 × 5 to get that the interest is $7500.00.

hope this helped! will you pls give a "thanks" and/or leave a brainllest since I had to do two different equations? :)

Given the expression: 5x^10-80x^2 Part A: Rewrite the expression by factoring out the greatest common factor
Jlenok [28]

Answer:

A) 5x²(x^(8) - 16)

B) 5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]

Step-by-step explanation:

We are given the expression;

5x^(10) - 80x²

A) Since the expression is, 5x^(10) - 80x², the greatest common factor is 5x². So we will factorize that out.

So, we have;

5x²(x^(8) - 16)

B) The complete factorization of 5x²(x^(8) - 16) will be;

5x²[(x⁴ + √16) • (x⁴ - √16)]

Now, (x⁴ - √16)] can be broken than further into;

(x² + ∜16) • (x² - ∜16)

Also, (x² - ∜16) can be broken down into;

[(x + (8√16) • (x - (8√16))

So, our complete factorization gives us;

5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]
