The radius is the line from any point on the circumference connected to the center of the circle. It is the distances that all points on the circle are from the center.

A chord is a line connecting any two points on the circumference to one another.

The diameter is any two points on the circumference that when connect intersect with the center, it is the magnitude of the longest chord possible and is twice the radius.

The center is that point from which all points on the circumference are an equal distance away from.

Given that g(x)=2x^2-5. Calculate g(x+4)+2

Dimas [21]

Answer:

$2x^2+16x+29$

Step-by-step explanation:

Given that,

$g(x)=2x^2-5$

We need to find g(x+4)+2

$g(x+4)=2(x+4)^2-5\\\\=2(x^2+16+8x)-5\\\\=2x^2+32+16x-5\\\\=2x^2+16x+27$

Now,

$g(x+4)+2=2x^2+16x+27+2\\\\=2x^2+16x+29$

So, the value of $g(x+4)+2$ is $2x^2+16x+29$

6x + 1 = 2(3x - 2) + 5 A) x = 0 B) x = 12 C) x = 1 12 D) infinitely many solutions

Alex17521 [72]

Answer:

D) infinitely many solutions

Step-by-step explanation:

6x + 1 = 2(3x - 2) + 5

Distribute

6x+1 = 6x -4+5

Combine like terms

6x+1 = 6x+1

Subtract 6x from each side

6x-6x+1 = 6x-6x+1

1=1

This is always true, so x has infinite solutions

What is the equation of the line perpendicular to the line y = four over nine x – 2 that passes through the point (4,3)?

satela [25.4K]

Let's take a look at the frist problem. 2 and 3 can be solved the same way.

First of all you have to rewrite your equation 3x + y = 5 (this is a standard form) in slope-intercept form by subtracting 3x from both sides of the equation. We have y = -3x +5. That means the sloppe of the line is

m=-3 (if we use y = mx+b form of the linear equation). The line which is perpendicular to that will have the slope equal to the reciprocal of (-3) taken with negative sign. Thus, the new slope equals 1/3. Or your equation for the perpendicular line should be like

y = (1/3)x +b

In order to find "b" use the point given in the problem. If x =-9 y =3. Thus, we have

3 = (1/3)(-9) +b = -3 +b or b = 3+3 =6

The equation for a perpendicular line becomes

y = (1/3)x +6

Repeat the same steps for problems 2 and 3.

Find the common denominator and equivalent fractions for this equation. 4/5+1/3

podryga [215]

Answer: 15, $\frac{17}{15}$

Step-by-step explanation:

The common denominator can be determined by taking LCM of 5 and 3

$\Rightarrow LCM(5,3)=15$

Now add the two fraction

$\Rightarrow \dfrac{4}{5}+\dfrac{1}{3}\\\\\Rightarrow \dfrac{4\times3+1\times 5}{15}=\dfrac{12+5}{15}\\\Rightarrow \dfrac{17}{15}$

Equivalent fraction is $\frac{17}{15}$
