Which number line represents all of the values of x for the equation x2 = 100

Mathematics
1 answer:
Hitman42 [59]3 years ago
4 0

x^2 = 100...by taking the square root of both sides, this eliminates the ^2

x = (+-) sqrt 100

x = (+-) 10

so the values of x are -10 and 10

1. Which of the following numbers is an example of an integer?
Leokris [45]
1. All whole numbers (0, 1, 2,...) and their negative equivalent ( -1, -2, -3, ...) are considered integers. Hence, from the choices provided, the answer would be A. 2. Real numbers consist of rational and irrational numbers. So the statement "Every real number is a rational number" is not correct. Thus, the answer is D. 3. 5.85, 63.4, and 27.5 are terminating decimals. This means that they have a fixed decimal conversion and does continue endlessly. Meanwhile, for 8.52624 . . ., its digit goes on forever. So, odd one out would be C. 4. Irrational numbers are those that cannot be expressed as the ratio of two numbers. Examples for this would be the value of the constant e, √2, etc. Rational numbers, on the other hand, are numbers that can be expressed as ratio of two numbers. As can be seen irrational and rational numbers are opposite of ech other, by definition. Hence, irrational numbers cannot be classified as rational numbers. That will give an answer of E. 5. From the previous items, we can see that both rational and irrational numbers are part of the real number system. This means that every irrational number is a real number. Hence, the answer is C. <span>Answers: A, D, C, E, C </span>

The formula for the volume V of a cylinder is LaTeX: V=\pi r^2hV = π r 2 h, where r is the radius of the base anThe formula for
Alekssandra [29.7K]

Answer:

h = \frac{V}{\pi r^2}

h = 4 cm

Step-by-step explanation:

Volume of cylinder is given as V = \pi r^2 h

V is the volume the cylinder, r is its radius at the base, while is its height.

To select the formula for h (height) let's make h the subject of the formula as follows:

V = \pi r^2 h

\frac{V}{\pi r^2} = \frac{\pi r^2 h}{\pi r^2} (dividing both sides of the equation by \pi r^2 )

\frac{V}{\pi r^2} = h

h = \frac{V}{\pi r^2}

Use the formula above to find the height of the given cylinder where Volume (V) = 36π cm³, and base radius (r) = 3 cm:

h = \frac{36 \pi}{\pi 3^2} (substitution)

h = \frac{36 \pi}{\pi * 9}

h = \frac{36 \pi}{9 \pi}

h = \frac{36 \pi}{\pi * 9}

h = \frac{36}{9} (\pi cancels \pi)

h = 4 cm

A trapezoid has bases that measure 10 cm and 6 cm. The height of the figure is 15 cm. What is the area of the trapezoid? A. 60 B
ki77a [65]

Answer:

C. 120

Step-by-step explanation:

area of trapezoid = (base1 + base2)h/2

area = (10 cm + 6 cm) * 15 cm/2

area = 16 cm * 15 cm / 2

area = (240 cm^2)/2

area = 120 cm^2

Solve the system.<br> 2x + y = −3 −2y = 6 + 4x<br> Write each equation in slope-intercept form.
Fantom [35]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

-------------------------------------

2x + y = -3       <em>subtract 2x from both sides</em>

y = -2x - 3


-2y = 6 + 4x

-2y = 4x + 6     <em>divide both sides by (-2)</em>

y = -2x - 3

We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions

x ∈ R

y = -2x - 3
