D) = -16t2 + 640

Answer:

there is no solution

Step-by-step explanation:

y = 2x + 1

put into other equation

2x - 2x + 1 = 3

0x + 1 = 3

0x = 2

0/0x = 2/0

x = undefined

Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together

33y + 24 = 90

solve for y

33y= 66. y= 2

now let's get the measurements of the angles

13(2) + 12= 38

20(2) + 12= 52

Answer:

False

Step-by-step explanation:

The range of the function is the set of all possible y values, in our case that would be {5, 6, 8, 13}, there for the range of the function is not {2, 4, 5, 6}, therefore the statement is false.

Answer:

4x2 - 3xy - 9y2

Step-by-step explanation:

The resultant force in the example presented is approximately 774 pounds.

The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.

Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.

Consider the following scenario: the force is 10 N in the east.

The direction is indicated by "towards the east," while the force is indicated by "10."

Magnitude can be thought of as simply the "value" or "amount" of any physical quantity.

So, an object is under the influence of two forces with respective magnitudes of 300 pounds and 450 pounds and an angle of 60 degrees between them.

F₁=300 pounds, F₂=450 pounds and θ=60°

Fr=√300²+450²+2×300×450×cos60°

= √90000+502500+13500×0.5

= √90000+502500+6750

= √599250

= 774 pounds

Therefore, the resultant force in the example presented is approximately 774 pounds.

90 pages in 10 hours :)

Answer:

90 pages

Step-by-step explanation:

First, you need to find the unit rate of how many pages he can read.

So, you divide 18 pages by 2 hours = 9 pages per hour.

Then, you multiply 9*10 hours to find out how many pages he will read in 10 hours.

You get 90.

Answer:

x = -4/5, y = 13/20

Step-by-step explanation:

-10x + 4 = 12

-10x = 8

x = -4/5

3x - 4y = -5

3(-4/5) - 4y = -5

-12/5 - 4y = -5

-4y = -13/5

y = 13/20

Double check:

3x - 4y = -5

3(-4/5) - 4(13/20) = -5

-12/5 - 13 = -5 (true)

Answer:

9.6

Step-by-step explanation:

Find the diagram attached. Using the similarity theorem of triangles

AC/AD = FH/EH

Given

AC = 24

AD = 35

FH = x

EH = 14

Substitute into the formula

24/35 = x/14

Cross multiply

35×x = 24×14

35x = 336

x = 336/35

x = 9.6

Hence the value of x is 9.6

Answer:

4/27=14.8%

Step-by-step explanation:

In order to solve this, we have to see first each option possible, there are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.

In order to calculate if this could happen at random we have to multiply all of the odds:

[tex]Probability: \frac{2}{3} *\frac{2}{3} *\frac{1}{3} \\Probability: \frac{2*2*1}{3*3*3} \\Probability: \frac{4}{27}[/tex]

So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.

There are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.

We need to now multiply the odds:

2/3x2/3x1/3

2x2x1/3x3x3

4/27

So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.

So now we know it is, %15 rounded but 14.8% not rounded.
