A circle has radius 50 cm. Which of these is closest to its area?

trapecia [35]

Answer:

C) 7854 cm²

Step-by-step explanation:

The formula for the area of a circle is A = πr²

Now just plug in the numbers

A = π (50²)

A = 2500π

Let's say pi is 3.14

A = 2500(3.14)

A ≈ 7850

The closest answer to this answer is C: 7854

Why is the initial value and y-intercept the same thing on a graph?? someone please explain

lapo4ka [179]

-y is the vertical line and -x is the horizontal line. The only reason they would say -y 3 is to let you know that is the vertical... so you don’t mess up and mark 3 on the -x (horizontal) line

Find the value of x such that 3^(x^2)/ (3^(2x))=27

cestrela7 [59]

This is how this one is done. I'm assuming by this type of a problem that you are in logs in math since you need to rules of logs to solve it. First things first...laws of exponents when the bases are like. Our base is a 3. Here's the problem written out: $\frac{3^ x^{2} }{3 ^{2x} } =27$ . The rules for exponents when dividing like bases is that you subtract the exponents. So we will do that: $3^{x^2-2x} =27$ . Since we are solving for x we need to find a way to get it down from its exponential position. We do that by takking the log of both sides. $log 3^{x^2-2x}=log27$ . Another rule of logs, the power rule, is that once we take the log of a base with an exponent, we can move the exponent down in front, like this: $x^2-2x[log(3)]=log27$ . Now we will divide both sides by log(3) to get $x^2-2x= \frac{log(27)}{log(3)}$ . We do that math on the right side on our calculator to get $x^2-2x=3$ . Now this is something we can handle. We have a second degree polynomial that we have to factor for x. Do that by moving the 3 over by subtraction. $x^2-2x-3=0$ . Factoring that you have that x = 3 and x = -1. There you go!

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A construction

Answer:

$y=\frac{11}{20}x+6$

Step-by-step explanation:

Given:

Two points are given

x = number of minutes

y = length of the lin

$(x_{1},y_{1} )$ ⇒ (0, 6)

$(x_{2},y_{2} )$ ⇒ (20, 17)

We need to find the equation that represents the relationship between x, y.

Solution:

Using slope formula to find the slope of the equation of the line.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute $(x_{1},y_{1} )$ = (0, 6) and $(x_{2},y_{2} )$ = (20, 17) in above equation.

$m=\frac{17-6}{20-0}\\m=\frac{11}{20}$

So, slope of the line $m = \frac{11}{20}$

Using point slope formula.

$(y-y_{1})=m(x-x_{1})$ ------------(1)

Where, m = slope of the line

Substitute $(x_{1},y_{1} )$ ⇒ (0, 6) and $m = \frac{11}{20}$ in equation 1.

$(y-6)=\frac{11}{20} (x-0)$

$y-6=\frac{11}{20}x$

Add 6 both side of the equation.

$y-6+6=\frac{11}{20}x+6$

$y=\frac{11}{20}x+6$

Therefore, the equation that represents the relationship between x and y is written as:

$y=\frac{11}{20}x+6$

Some one help me on this one

aleksandrvk [35]

The answer is III only, or D.

We can start to solve this by knowing what the HL theorem means. The HL theorem, like its name implies, shows says that if a hypotenuse and leg of a triangle are congruent to the hypotenuse and leg of a different triangle, then the triangles are congruent. The only triangle that we see a hypotenuse congruent in is in figure III. In figure II, those congruent sides are both legs while in figure I we just see 2 congruent angles. Now in figure III, we can also see that two legs are congruent because of the reflexive property. That means that the answer is III, or D.
