I NEED THIS ANSWER ASAP!!!!

Naddik [55]

Solution:

We know the following rules:

Rule: If an exponent is negative, it will be in the fraction 1/nˣ.
Rule: If an exponent is positive, it will be in whole number form and will multiply itself m times.
Rule: if a number's exponent is 0, then the number is 1.

Now, let's solve each problem.

Question-7

4³ = 4 x 4 x 4 = 64
4² = 4 x 4 = 16
4¹ = 4
4⁰ = 1

Question-8

(-2)³ = (-2) x (-2) x -(2) = -8
(-2)² = (-2) x (-2) = 4
(-2)¹ = -2
(-2)⁰ = 1

What is the equation of the line that is perpendicular to the like y=-4x + 7 and passes through the point (8,2)?

Nookie1986 [14]

Answer:

$y=\frac{1}{4}x$

Step-by-step explanation:

Given equation of line:

$y=-4x+7$

To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).

Applying slope relationship between perpendicular lines.

$m_1=-\frac{1}{m_2}$

where $m_1$ and $m_2$ are slopes of perpendicular lines.

For the given equation in the form $y=mx+b$ the slope $m_2$ can be found by comparing $y=-4x+3$ with standard form.

∴ $m_2=-4$

Thus slope of line perpendicular to this line $m_1$ would be given as:

$m_1=-\frac{1}{-4}$

∴ $m_1=\frac{1}{4}$

The line passes through point (8,2)

Using point slope form:

$y_-y_1=m(x_-x_1)$

Where $(x_1,y_1)\rightarrow (8,2)$ and $m=m_1=\frac{1}{4}$

So,

$y-2=\frac{1}{4}(x-8)$

Using distribution.

$y-2=(\frac{1}{4}x)-(\frac{1}{4}\times 8)$

$y-2=\frac{1}{4}x-2$

Adding 2 to both sides.

$y-2+2=\frac{1}{4}x-2+2$

$y=\frac{1}{4}x$

Thus the equation of line in standard form is given by:

$y=\frac{1}{4}x$

St lies on the coordinate plane with s located at (3.2). The midpoint of dt is z(3,9) state the location of the endpoint T thank

77julia77 [94]

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)

Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 4:7. What are the measures of those t

Andrews [41]

Answer:

all angles will be 200, 50 , 40 and 70 - hope this helped :)

Step-by-step explanation:

everything equals to 360 after added together

360 - 250 = 110

110 divided by 11 = 10

4:7 (x 10)

40:70

the other angels will be 40 and 70
