Step-by-step explanation:

the was I understand matrix multiplication, I re-learned tonight so I could be wrong but.....

according to Gaggle    matrix multiplication is possible when the number of columns in matrix 1  equals the number of rows in matrix 2

       it is called the dot product  (that sounds familiar)

first choice has 2 columns  and 1 row              can't multiple this one

second choice has 1 column  and 2 rows        can't multiple this one

third choice has 2 columns  and 1 row             can't multiple this one

fourth choice has 1 column  and 1 row        This one can be multiplied

A trebuchet launches a pumpkin on a parabolic arc from a height of 47 ft at a velocity of 40 ft/s which gives the
following function equation h(t)= -16t^2 + 40t + 47. State the vocabulary term that is being described by the
following questions. Do not solve for any of the key features. questions a b c and d
a. When will the pumpkin reach the ground?
The pumpkin will reach the ground at
b. What is the maximum height the pumpkin reaches?
C. When does the pumpkin reach its maximum height?
d. What is the starting height of the pumpkin?

Answers

Answer:

a) 3.37 seconds

b) 75.85 feet

c) 1.25 seconds

d) 47 feet

Step-by-step explanation:

a) I could use kinematic equations here, but I'll use the one provided. Height as a function of time equals 0 when the pumpkin reaches the ground, so 0=(-16t^2)+40t+47 is your equation here. Solve for t. t=3.37

b) If you have a graphing calculator, just use maximum feature. If not, use the formula x=-b/2a. x=-40/-32, x=1.25.

Now, plug 1.25 in as t, and you'll get y=75.85ft

c) alreaady found in previous part

d) this is the constant in the formula, or the y-intercept, which is 47 (because there's no variable attached).

An 18-feet ladder is leaning against the side of a building. The angle between the ladder and the ground is 30°.
How high up on the building, from the ground, is the top of the ladder?

Answers

9514 1404 393

Answer:

  9 feet

Step-by-step explanation:

The sine relation applies.

  Sin = Opposite/Hypotenuse

  sin(30°) = height/(18 ft)

  height = (18 ft)sin(30°) = (18 ft)(1/2)

  height = 9 ft

The ladder extends 9 feet up the side of the building.

The three squares below join together to form a right triangle. The area and the perimeter for two of the squares is shown. Find the side length of the largest square.

Answers

Answer:

YES

Step-by-step explanation:

by dividing perimeter by 4, we

get the side lengths of 12, 35 and 37.

122 + 352 = 372.

The side length of the largest square is 15 inches.

From the given figure, area of one of the square is 81 square inches and the perimeter of another square is 48 inches.

What is the perimeter?

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

We know that, the area of a square = a²

Here, a²=81 square inches

⇒ a=9 inches

The perimeter of square = 4s

⇒ 4s=48

⇒ s = 12 inches

In the given figure, let the hypotenuse of triangle be x

Using Pythagoras theorem, we get

Now, x²=a²+s²

⇒ x²=9²+12²

= 81+144

= 225

So, x=15 inches

Therefore, the side length of the largest square is 15 inches.

5.Regarding the equations below. What is the value of x?

5x + 2y = 4
x – 3y = –23

Answers

Answer:

x=−2

y=7

Step-by-step explanation:

5x+2y=4

x−3y=−23

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

5x+2y=4,x−3y=−23

To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.

5x+2y=4,5x+5(−3)y=5(−23)

Simplify.

5x+2y=4,5x−15y=−115

Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.

5x−5x+2y+15y=4+115

Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.

2y+15y=4+115

Add 2y to 15y.

17y=4+115

Add 4 to 115.

17y=119

Divide both sides by 17.

y=7

Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.

x−3×7=−23

Multiply −3 times 7.

x−21=−23

Add 21 to both sides of the equation.

x=−2

The system is now solved.

x=−2,y=7

He puts some money in a new bank account and withdrawals the same amount once a week to try his luck at winning the jackpot. After three straight weeks of no luck, Jeffrey has $205 left in his account. After twelve total weeks, he still hasn’t won a thing and has $160 left to spend.
Karen, on the other hand, knows the odds of winning are almost impossible, and decides to start a savings account instead at the same time as Jeffrey. Karen consistently deposits $7 each week into her account, and after seven weeks has a total savings of $89. Unfortunately, Karen’s account does not earn any interest due to the extremely low interest rate.
