The shape formed by two square bases and four rectangles is a rectangular prism. In this shape, four sides are the same, and the two squares on the end are also the same

The correct answer is:

This is a rectangular prism.

Explanation:

A prism is a three-dimensional figure with two congruent, parallel bases connected by a height. If this were a cube, all of the faces, the bases and lateral faces, would be squares.

However, in this figure, the lateral faces are rectangles; this makes it a rectangular prism.

Jessica wants to buy 6 ounces of gluten-free edible cookie dough that costs $1.50 per ounce. Select all equations that correctly

mars1129 [50]

Answer:

9 dollars

Step-by-step explanation:

Hello you did not provide the options for me to select from. But I have gone ahead to calculate how much jessica would pay for her cookie dough.

I used this formula to arrive at this answer.

Cost of dough = quantity x price per ounce

Quantity = 6 ounces

Price per ounce = 1.5 dollars

Cost of dough = 6 x 1.50

= $9

Jessica is going to pay 9 dollars for her cookie dough

Two particles move in the xy-plane. At time t, the position of particle A is given by x(t)=5t−5 and y(t)=2t−k, and the position

Ipatiy [6.2K]

Answer:

Part A) Not collide

Part B) k = 4

Part C) Particle B is moving fast.

Step-by-step explanation:

Two particles move in the xy-plane. At time, t

Position of particle A:-

$x(t)=5t-5$

$y(t)=2t-k$

Position of particles B:-

$x(t)=4t$

$y(t)=t^2-2t+1$

Part A) For k = -6

Position particle A, (5t-5,2t+6)

Position of particle B, $(4t,t^2-2t-1)$

If both collides then x and y coordinate must be same

Therefore,

For x-coordinate:

5t - 5 = 4t

t = 5

For y-coordinate:

$2t+6=t^2-2t-1$

$t^2-4t-7=0$

$t=-1.3,5.3$

The value of t is not same. So, k = -6 A and B will not collide.

Part B) If both collides then x and y coordinate must be same

For x-coordinate:

5t - 5 = 4t

t = 5

For y-coordinate:

$2t-k=t^2-2t-1$

Put t = 5

$10-k=25-10-1$

$k=4$

Hence, if k = 4 then A and B collide.

Part C)

Speed of particle A, $\dfrac{dA}{dt}$

$\dfrac{dA}{dt}=\dfrac{dy}{dt}\cdot \dfrac{dt}{dx}$

$\dfrac{dA}{dt}=2\cdot \dfrac{1}{5}\approx 0.4$

Speed of particle B, $\dfrac{dB}{dt}$

$\dfrac{dB}{dt}=\dfrac{dy}{dt}\cdot \dfrac{dt}{dx}$

$\dfrac{dB}{dt}=2t-2\cdot \dfrac{1}{4}$

At t = 5

$\dfrac{dB}{dt}=10-2\cdot \dfrac{1}{4}=2$

Hence, Particle B moves faster than particle A

If two distinct lines intersect, which is NOT necessarily true? A) The lines are not parallel. B) The lines are perpendicular. C

SVEN [57.7K]

Answer:

B is not necessarily true

Step-by-step explanation:

A) This is always true

B) This is not necessarily true

When two lines intersect, they form angles at the intersection as D says, but that does not mean that the angle will always be 90 degrees as is required for the two intersecting lines to be perpendicular

C) This is always true

D) This is always true

John read the first 114 pages of a novel, which was 3 pages less than 1/3 of the novel. Write an equation to determine the total

GREYUIT [131]

114 + 3=117
117 pages is 1/3 of the book
117×3= 251
So there are 251 pages in the novel.
