The value of 5.7 x 10⁸ is 570,000,000 CHOICE C.

The value of 8⁴ is 8 * 8 * 8 * 8 = 4,096 CHOICE C.

Prime factorization of 1,260

1260 ÷ 2 = 630
630 ÷ 2 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7

2 x 2 x 3 x 3 x 5 x 7 CHOICE D.

Composite numbers are numbers that have more factors other than 1 and itself.

91 / 1 = 91
91 / 7 = 13 CHOICE C. 91 is a composite number.

Given ACM, angle C=90º. AP=9, PM=12. Find AC, CM, AM.

Gnesinka [82]

Answer:

AM = 25, AC = 15, CM = 20

Step-by-step explanation:

The given parameters are;

In ΔACM, ∠C = 90°, $\overline{CP}$ ⊥ $\overline{AM}$ , AP = 9, and PM = 16

$\overline{AC}$ ² + $\overline{CM}$ ² = $\overline{AM}$ ²

$\overline{AM}$ = $\overline{AP}$ + PM = 9 + 16 = 25

$\overline{AM}$ = 25

$\overline{AC}$ ² = $\overline{AP}$ ² + $\overline{CP}$ ² = 9² + $\overline{CP}$ ²

∴ $\overline{AC}$ ² = 9² + $\overline{CP}$ ²

Similarly we get;

$\overline{CM}$ ² = 16² + $\overline{CP}$ ²

Therefore, we get;

$\overline{AC}$ ² + $\overline{CM}$ ² = 9² + $\overline{CP}$ ² + 16² + $\overline{CP}$ ² = $\overline{AM}$ ² = 25²

2· $\overline{CP}$ ² = 25² - (9² + 16²) = 288

$\overline{CP}$ ² = 288/2 = 144

$\overline{CP}$ = √144 = 12

From $\overline{AC}$ ² = 9² + $\overline{CP}$ ², we get

$\overline{AC}$ = √(9² + 12²) = 15

$\overline{AC}$ = 15

From, $\overline{CM}$ ² = 16² + $\overline{CP}$ ², we get;

$\overline{CM}$ = √(16² + 12²) = 20

$\overline{CM}$ = 20.

What is simplest form of sqrt 2 + sqrt 5 / sqrt 2 - sqrt -5? √2 + √5 / √2 - √-5

Leni [432]

Answer:

$\frac{-7-2\sqrt{10}}{3}$

Step-by-step explanation:

we have

$\frac{\sqrt{2}+\sqrt{5}}{\sqrt{2}-\sqrt{5}}$

Simplify

Multiply the expression by $\frac{\sqrt{2}+\sqrt{5}}{\sqrt{2}+\sqrt{5}}$

$(\frac{\sqrt{2}+\sqrt{5}}{\sqrt{2}-\sqrt{5}})(\frac{\sqrt{2}+\sqrt{5}}{\sqrt{2}+\sqrt{5}})$

Apply difference of squares in the denominator

$\frac{(\sqrt{2}+\sqrt{5})^2}{(\sqrt{2})^2-(\sqrt{5})^2}$

$\frac{2+2\sqrt{10}+5}{2-5}$

$\frac{7+2\sqrt{10}}{-3}$

$\frac{-7-2\sqrt{10}}{3}$
