The student would get an 80%.

Since 5 is 20% of 25, subtract 20 from 100 and you get 80%

- 9(x + 2) > 9(x – 3)

mezya [45]

Answer:

x < 1/2

Step-by-step explanation:

Distribute: -9x - 18 > 9x - 27

Collect like terms: -18x > -9

Divide both sides by -18: x < 1/2.

The sign changes because both sides were divided by a negative number.

andrey2020 [161]

Answer:

Does not make a triangle

Step-by-step explanation:

The Pythagorean theorem is

a^2 + b^2 = c^2

a+b > c

22+32 =54 This is less than 55 so this does not make a triangle

The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?

Katena32 [7]

A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.

This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.

x + x + 40 = 180

2x + 40 = 180

2x = 140

x = 70

The base angles measure 70 deg.

Oi

Just calculating the differential. Step by step:

$y=12 \sqrt{x} -x \frac{3}{2}-10 \\ \\ y=12x^{ \frac{1}{2} } -x \frac{3}{2}-10 \ \ \ \boxed{transform \ \sqrt{x} =x^{ \frac{1}{2} }} \\ \\ Differentiating \\ \\ y'=12. \frac{1}{2}.x^{ \frac{1}{2}-1 } -1.x^{1-1}. \frac{3}{2}-0 \\ \\ y'=6.x^{ -\frac{1}{2} } -x^{0}. \frac{3}{2} \\ \\ y'=6. \frac{1}{x^{ \frac{1}{2} }} -1. \frac{3}{2} \\ \\ \boxed{y'=\frac{6}{ \sqrt{x} } -\frac{3}{2}}$

If you want to know where the tangent has no slope:

$\frac{6}{ \sqrt{x} } - \frac{3}{2} =0 \\ \\ \frac{6}{ \sqrt{x} } = \frac{3}{2} \\ \\ 3 \sqrt{x} =12 \\ \\ \sqrt{x} = \frac{12}{3} \\ \\ \sqrt{x} =4 \\ \\ (\sqrt{x})^2 =4^2 \\ \\ x=16$

Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed.
