Which line passes through the origin? A. y=3 B. y=x−3 C. y=−3x D. y=2x+1
eimsori [14]

Answer:

C

Step-by-step explanation:

A is a horizontal line on 3

B will cross the y axis at (0, -3), and the x axis (3, 0)

D will cross the y axis (0, 1) and the x axis (-0.5, 0)

As C does not have a y-intercept or x-intercept, it will it (0, 0)

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the re
mina [271]

Answer:

Step-by-step explanation:

integrate with respect to x

Area is symmetric so will be twice the integral from zero to 1

( I cannot seem to figure out how to make the lower limit negative in this editor)

A = 2\int\limits^1_0 {(x^2 + 3) - 4x^2} \, dx)

A = 2\int\limits^1_0 {-3x^2 + 3} \, dx

A = 6\int\limits^1_0 {-x^2 + 1} \, dx

A = 6(-⅓x³ + x)\left \| {{x=1} \atop {x=0}} \right.

A = 6((-⅓(1)³ + (1)) - (-⅓(0)³ + (0)))

A = 6(⅔)

A = 4 units²

For Part A: You would put a dot on -8 on your line graph, and also put a dot on 13 as well. This is representing the temperatures of White Plains, NY.

For part B: The answer would be 21 degrees warmer.

Hope this helps!
