Answer:

$\huge\boxed{-21}$

Step-by-step explanation:

-x²-5y³

Given that x = 4, y = 1

$-(4)^2-5(1)^3$

$-16-5(1)\\-16-5\\-21$

Jessica locates her garden using a coordinate grid with yards as the units. The two points

Oliga [24]

Answer:

These two corners are $\sqrt{13}$ units apart.

Step-by-step explanation:

Distance between two points:

Suppose we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between them is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Approximately how far apart are the two corners?

We have to find the distance between the points (-5,-2) and (-8-3). So

$D = \sqrt{(5-(-8))^2+(-2-(-3))^2} = \sqrt{13}$

These two corners are $\sqrt{13}$ units apart.

What is the simplest form of expression? 2a^2b^2/4a

34kurt

The 2 from the a and the 4 will reduce to 1/2 and the a's from a^2 and 4a will reduce to a/1 so your answer would be (ab^2)/2

What is the surface area of a cylinder with a radius of 5 ft and a height of 2 ft?

icang [17]

$\bf \textit{total surface area of a cylinder}\\\\
SA=2\pi r(h+r)~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=5\\
h=2
\end{cases}\implies SA=2\pi (5)(2+5)
\\\\\\
SA=10\pi (7)\implies SA=70\pi$

WILL NAME BRAINLEST ONGG <br> PLEASE HELP

Leona [35]

Answer:

since angle 1 and angle 2 are equal both angles can only be 90.

and given that b is perpendicular to d so angle at point of interception of bd is also 90.

it is also given that c and d are parallel so both line have same angle on point of interception of line a and b and angle formed is also the same on line a and b .....so a and b are parallell
