A table has five bowls. None of the quantities in the bowls are prime, though the last two bowls are empty. Two of the quantitie

Digiron [165]

Since two of the quantities are squares and the sum of all of three is equal 21, then the possible values of those two quantities are: 1,4,9,16

Let's consider each possibility

1 and 4

21-1-4=16, but 16 is also square and there can be only two square so NO

1 and 9

21-1-9=11, but 11 is prime, so NO

1 and 16

21-1-16=4... 4 is a square ,so NO

4 and 9

21-4-9=8 , 8 is not prime and not a square, so YES

4 and 16

21-4-16=1, but 1 is a square ,so NO

9 and 16

9+16=25>21 so.. NO

Therefore, the amounts in the first three bowls are 4,8,9.

What is Sn for the arithmetic series in which a1=16 , an=98 and n =13?

N76 [4]

Answer:741

Step-by-step explanation:

Given

First term $a_1=16$

last term $a_n=98$

and no of terms $n=13$

And sum of n terms is given by

$S_n=\frac{n}{2}[a_1+a_n]$

$S_n=\frac{13}{2}[16+98]$

$S_n=\frac{13\times 114}{2}$

$S_n=13\times 57$

$S_n=741$

Sp sum of n terms is 741

X = 4

Explanation:

sqrt(x) + sqrt(5 + x) = 15 / sqrt(5 + x)

sqrt(5 + x)[sqrt(x) + sqrt(5 + x)] = 15

sqrt(5x + x^2) + 5 + x = 15

sqrt(5x + x^2) = 10 - x

Take square of both sides

5x + x^2 = (10 - x)^2

5x + x^2 = 100 - 20x + x^2

Cancel x^2

5x = 100 - 20x

25x = 100

x = 4

The graph of a quadratic function is shown above.

OleMash [197]

Answer:

0 real zeros
2 complex zeros

Step-by-step explanation:

The "fundamental theorem of algebra" says a polynomial of degree n will have n zeros. If the polynomial has real coefficients, the complex zeros will appear in conjugate pairs.

The graph of this quadratic (degree = 2) does not cross the x-axis, so there are no real values of x that make y=0. That means the two zeros are both complex.
