What is the slope of each side of the triangle? the sides are A(-2,4) B(-1,1) C(2,3)

Rashid [163]

Answer:

The slopes of three sides of triangle are as follows:

AB = -3

BC = 2/3

AC = -1/4

Step-by-step explanation:

The slope is denoted by m and is calculated using the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

The given vertices are:

A(-2,4) B(-1,1) C(2,3)

The sides will be:

AB, BC, AC

Let m1 be the slope of AB

Let m2 be the slope of BC

Let m3 be the slope of AC

Now

$Slope\ of\ AB = m_1 = \frac{1-4}{-1+2} = \frac{-3}{1} = -3\\Slope\ of\ BC = m_2 = \frac{3-1}{2+1} = \frac{2}{3}\\Slope\ of\ AC = m_2 = \frac{3-4}{2+2} = \frac{-1}{4} = -\frac{1}{4}$

Hence,

The slopes of three sides of triangle are as follows:

AB = -3

BC = 2/3

AC = -1/4

If isme estimated that there are 50 students in the seventh grade class but there are actually 40 what is isme’s percent error?

Temka [501]

The percent error is 25 %

Solution:

Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40

To find: percent error

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

The formula for percent error is given as:

$\text{ percent error }=\frac{\text { approximate value }-\text {exact value}}{\text { exact value }} \times 100$$

Here, exact value = 40 and approximate value or estimated value = 50

Substituting the values in above formula,

$\begin{aligned}&\text { percent error }=\frac{50-40}{40} \times 100\\\\&\text { percent error }=\frac{10}{40} \times 100=\frac{100}{4}=25\end{aligned}$

Thus the percent error is 25 %

The black graph is the graph of y=f(x). Choose the equation for the red graph. Please Help me!!

katen-ka-za [31]

Answer:

Step-by-step explanation:

The red graph is the black graph translated vertically by 1 unit

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus f(x) + 1

Note

y - 1 = f(x) ← add 1 to both sides

y = f(x) + 1 ← as required

The equation of the red graph is

y - 1 = f(x) → c
