Can someone please help me

Bad White [126]

Answer:

Step-by-step explanation:

Lateral Area:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a traingle:

$A_\triangle=\dfrac{bh}{2}$

Substitute:

$A_\triangle=\dfrac{(16)(12)}{2}=(8)(12)=96\ cm^2$

$L.A.=4A_\triangle=4(96)=384\ cm^2$

Surface Area:

$S.A.=B+L.A.$

In the base we have the square with side s = 16cm. The formula of an area of a square:

$A_\square=s^2$

Substitute:

$B=16^2=256\ cm^2$

$S.A.=256\ cm^2+384\ cm^2=640\ cm^2$

I need help ASAP!!!!

Ymorist [56]

I started this one then got busy with other things.

z and 71 deg form a same side interior pattern

they're supplementary angles

sum to 180 degrees

z + 71 = 180

z = 180 - 71

z = 109 degrees

z and x are alternate angles

their measures are the same

z = 109 deg so x = 109 deg

y and 71 deg form adjacent angles which are supplementary

sum to 180 degrees

y = 180 - 71 = 109 deg

x = 109 deg, y = 109 deg, z = 109 deg

Part b

w and 88 form a supplementary pair

they add to 180 deg

w = 180 - 88 = 92 deg

v and 101 deg are vertical or opposite angles

They are congruent

So v = 101 deg

Find the equation of the linear function represented by the table below in slope-intercept form.Answer: ?(Important: Please chec

Salsk061 [2.6K]

The Slope-Intercept form of the equation of the line is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

The slope can be found with:

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

Choose two points from the table. These could be the points (1,-4) and (4,-19). You can set up that:

$\begin{gathered} y_2=-19 \\ y_1=-4 \\ x_2=4 \\ x_1=1 \end{gathered}$

Substituting values, you get that the slope of this line is:

$m=\frac{-19-(-4)}{4-1}=-5$

You can substitute the slope and the first point into the equation in Slope-Intercept form:

$-4=1(-5)+b$

Solve for "b":

$\begin{gathered} -4+5=b \\ b=1 \end{gathered}$

Therefore, the Equation of this line in Slope-Intercept form is:

$y=-5x+1$
