Evaluate the expression.
Katarina [22]

Answer:

11

Step-by-step explanation:

The lines on the outside simply means "absolute value". This just takes any negative number and makes it positive. In this case, 15-4 is already positive so the answer is just positive 11.

Which of the following statement(S) are true of the discriminant?
lana [24]

Hello from MrBillDoesMath!

Answer:    A, C, D

Discussion:

The solution of the quadratic equation  ax^2 + bx + c = 0  is


x =        ( -b  +\-   (b^2 - 4ac) ^ (1/2) ) /2a


The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution,  and also occurs inside a square root (called a radicand).

The question, while intelligible, should be stated more clearly.  

Regards, MrB

Rebecca went swimming yesterday. After a while she had covered one fifth of her intended distance. After swimming six more lengt
alukav5142 [94]

Answer:

Option E.

Step-by-step explanation:

Let the intended length of Rebecca's swimming is = x units

and we assume the length of the pool = l units

Now it is given in the question that " She covers one fifth of her intended distance "

That means distance covered = \frac{x}{5}

" After swimming six more lengths of the pool she had covered one quarter of her intended distance"

So \frac{x}{5}+6(l)=\frac{x}{4}

6l=\frac{x}{4}-\frac{x}{5}

6l=\frac{x}{20}

x = 20×(6l)

x = 120l

Therefore, Rebecca has to complete 120 lengths of the pool.

Option E is the answer.

You can make small 20 small frames in 4 days or 21 large frames in 3 days. A customer has just place a order with you for 40 sma
cupoosta [38]

Answer:

I got 17.

Step-by-step explanation:

Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)
