Graph the function y=2 sqrt x+4 and state the transformation from the parent graph y= sqrt x

Darya [45]

Answer:

Step-by-step explanation:

Please use parentheses so that there's no question about what constitutes the argument of the sqrt function:

y=2 sqrt x+4 → y = 2√(x + 4)

This result is obtained from y = √x by:

1) translating the graph of y = √x 4 units to the LEFT, and

2) stretching the resulting graph vertically by a factor of 2.

You are asked to draw a triangle using three of the following angles: 0°, 30°, 45°, 55°, 60°, 80°, 90°, 105°. Which triangle can

BabaBlast [244]

Any triangle where the sum of the angles is over or under 180 cannot exist.
A 45-55-80 triangle can exist, but a 45-55-90 triangle cannot.
A 30-45-105 triangle can exist, but a 80-90-105 triangle cannot.

If a circle has a radius of 12 units what is its area?

Marysya12 [62]

To solve this problem, we will visit the area of a circle formula and supply known values, such as the radius, to answer the question.

<h3>Define</h3>

To find the area of a circle given its radius, use the formula:

$A = \pi r ^2$

where $r$ is the radius of the circle and A is the area.

<h3>Substitute</h3>

Substitute the known value for the radius in the formula.

$A = \pi(12)^2$

<h3>Simplify</h3>

To simplify, use BPEMDAS, which evaluates in the proper Order of Operations:

Brackets

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

Use BPEMDAS:

$A=\pi(144)$

Simplify by rearranging the coefficient in front of the variable:

$A=144\pi$

As this is an area, our final result must be squared:

$A=144\pi \text{ square units}$

The final answer to this problem is $A=144\pi$ square units. The answer can also be represented in a non-exact (approximate) format, which is solved below.

<h3>Approximate Format</h3>

To get the non-exact format of this answer, instead of leaving $\pi$ in the final answer, multiply it by the leading coefficient.
