Answer:

The sum (answer) is [-1, 2, 1, 9].

Step-by-step explanation:

Here we're asked to sum up two matrices of the same dimensions (1 by 4).

The value in the first matrix, first column, is 1; that in the second matrix, first column, is -2. Combining 1 and -2, we get -1, which is the first column value in the answer matrix.

Continuing in the same manner: -4 + 6 = 2; 3 - 2 = 1; and 5 + 4 = 9.

The sum (answer) is [-1, 2, 1, 9].

mark wants to order a pizza. which is the better deal 10.00 with a diameter of 12 or 20.00 with a diameter of 18

satela [25.4K]

I'm gonna calculate by the area of pizza to see how much food you get for 10 and 20 dollars

A...area
r...radius
d...diameter

d1=12 r1=6
d2=18 r2=9

A1=r1^2×3.14
A1=6^2×3.14
A1=36×3.14
A1=113.04

A2=r2^2×3.13
A2=9^2×3.14
A2=81×3.14
A2=254.34

if you bought 2, 12 diameter pizzas for 20 dollars you would get 226.08 area od food,still less if you bought 1, 18 diameter pizza for 20 dollars. because 223.08 < 254.34

Determine the slope of a line that is perpendicular to the line whose equation is x - 2y = 6.

Degger [83]

Answer:

The answer is -1/2

Step-by-step explanation:

We first start by removing x in order isolate the y variable

2y = 6 - x

y = $\frac{6-x}{2}$

Further, we simplify the equation in order to get the value of m (slope)

y = 3 + $\frac{-1x}{2}$

Therefore, our slope is equivalent to -1/2
