Answer: Option A

Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.

the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.

The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.

I believe the answer is C.

93.53 - 21.41 = 72.12

If you simplify C, its answer becomes equivalent to the answer of the original problem:

(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)

70 + 2 + 0.1 + 0.02

72.12

Simplify ( √ 5 ) ( 3 √ 5 )

Amiraneli [1.4K]

Answer:

$5^\frac{5}{6}$

Step-by-step explanation:

$\sqrt{5}$ can be represented as $5^{\frac{1}{2}}$ and $\sqrt[3]5}$ can be represented as $5^{\frac{1}{3}}$ . Therefore, the expression can be rewritten as:

$5^{\frac{1}{2}}*5^{\frac{1}{3}}$

The rule for multiplying two exponents with the same base is you add the exponents. For example: $x^m*x^k=x^{m+k}$

We can use the same property to get:

$5^{\frac{1}{2} +\frac{1}{3}}$

which is just $5^\frac{5}{6}$ after you add the fractions

3.) 2x + 4 = -3x - 2; x = 1<br><br>Determine if the value of x is a solution to the equation

guajiro [1.7K]

Answer:

x = 1 is not a solution to the equation

Step-by-step explanation:

2x + 4 = -3x - 2 x = 1

2(1) + 4 = -3(1) - 2

2 + 4 = -3 - 2

6 = -5 FALSE

ANSWER

$10.18$

EXPLANATION

We want to approximate, using the ALEKS calculator, the value of:

$\sqrt[]{103.7}$

To do this, we input the radical and the number into the calculator. The result is:

$10.18331969$

Since we have to round the answer to the nearest hundredth, we will pick the number in the thousandths place value, which is 3.

This number is less than 5, so, we round it down to 0 and add it to the number in the hundredth place value, which is 8.

Hence, the answer is:

$10.18$
