Answer:

FALSE

Step-by-step explanation:

We are assuming that t is a real number.

Thus, cos(t) is a real number greater than or equal to -1 and less than or equal to +1.  

Thus, cos(t) = 3 is false for all real t, and so in particular it is false for the value(s) of t such that tan(t) = 2/3.

Answer:

1. there are 0 4s in 0 so the first one is 0

2. you can not reach to 8 with 0s, so the answer is undefined

Answer: Option A.

Step-by-step explanation: Draw a number line from negative 5 to positive 5 with increments of 0.5. Make an empty circle on the first mark to the left of 0. It means mark an open circle at -0.5.

The region to the left of the empty circle is shaded. It means all the points lie on the left side of -0.5 at in the shaded region.

We need to find a statement that explains whether −1.5 can be a value in the shaded region.

Since −1.5 lies to the left of −0.5 , therefore -1.5 is in the shaded region.

Therefore, the correct option is A.

Answer: The answer is A

Step-by-step explanation:

Answer:

<1 = 58 , <2 = 122, <3 = 58

Step-by-step explanation:

concept #1: a straight line has an angle of 180.

180 -122 = 58

concept #2: a angle across from another(in which they share a common point made by two lines crossing each other) have essentially the same angle degree

<2 = 122

there <3 is also angle degree of <1 which is 58

Answer:

2^7

Step-by-step explanation:

Dividing fractions with exponents means you subtract, so 2^6/2^4 = 2^6-4 =2^2

Multiplying numbers with exponents means adding the exponents, so 2^2+2^5 = 2^2+5 = 2^7

Answer:

Step-by-step explanation: I am trying to interpret the question: I'll assume:

Line AB has a midpoint, M.

A is (8,4)

B is unknown, but desired

M is (3,-2)

We'll assume a straight line of the form y=mx+b, where m is the slope. m can be calculated by the "Rise" over the "Run" between the points A and M:

Rise = (4-(-2))=6

Run = (8-3)=5

Slope = (Rise/Run) = (6/5)

The line becomes y=(6/5)x+b

Calculate b, the y-intercept (the value of y when x is 0), by entering one of the two known points. I'll choose (8,4).

y=(6/5)x+b

4 = (6/5)(8)+b

b = 4 - (6/5)(8)

b = 4 - (48/5)

b = 4 - (9 3/5) or -5 3/5

The equation becomes:

y=(6/5)x - 5 3/5

Point B will have an x value of -2 [The change in x from A to M was (3-8) = -5. From M to 5 would be another -5 increment, so x goes from 3 to (3-5) or -2.

Find the value of y for x=-2:

y=(6/5)x - 5 3/5

y=(6/5)*(-2) - 5 3/5

y=(-12/5) - (28/5)

y = -(40/5) or - 8

B has coordinates of (-2, -8)

If coordinates of point A is (8, 4), then the coordinate of point B will be (-2, -8).

The "Midpoint-Formula" is used to find the coordinates of a point that lies exactly halfway between two given points. It's given as :Midpoint (M) = ((x₁ + x₂)/2, (y₁ + y₂)/2),

In this case, we have the midpoint as M(3, -2) and one of the endpoints as A(8, 4). We need to find coordinates of other endpoint which is B,

Using the midpoint formula, we rearrange it to solve for the missing coordinates (x₂, y₂),

x₂ = 2 × Mₓ - x₁,

y₂ = 2 × [tex]M_{y}[/tex] - y₁,

Substitute the given values:

We have : Mₓ = 3; [tex]M_{y}[/tex] = -2,

x₁ = 8; y₁ = 4

x₂ = 2 × 3 - 8 = -2;   y₂ = 2 × -2 - 4 = -8,

Therefore, the coordinates of point-B is(-2, -8).

The cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.

We have the church youth group is selling snacks to raise money to attend their convention.

We have to determine the cost of each item they sold.

The mathematical equation representing the above statement is -

2x + 5y = 50

According to question -

Assume that the cost of :

1 pound candy = $x

1 box of cookies = $y

1 can of popcorn = $z

Now, write down the mathematical equation representing their total sales -

Amy -      2x + 3y + z = 85

Brian -     4x + 4y + 3z = 170

Paulina -     8x + 8y + 5z = 330

We will use the Cramer's rule to solve these equations -

The 3 x 3 coefficient matrix is -

[tex]\left[\begin{array}{ccc}2&3&1\\4&4&3\\8&8&5\end{array}\right][/tex]

Find its determinant -

D = 2(4 x 5 - 3 x 8) - 3(4 x 5 - 8 x 3) + 1(4 x 8 - 4 x 8) = 4

Create the X- matrix (X - matrix is formed by replacing the x-column values with the answer-column values) as follows -

[tex]\left[\begin{array}{ccc}85&3&1\\170&4&3\\330&8&5\end{array}\right][/tex]

Find th determinant of this X - matrix same as done above -

D(X) = 120

Similarly create a Y - matrix and Z - matrix and find their respective determinants. On solving you will get -

D(Y) = 20

D(Z) = 40

According to the Cramer's rule -

[tex]$x = \frac{D_{x} }{D}[/tex]

[tex]$y = \frac{D_{y} }{D}[/tex]

[tex]$z = \frac{D_{z} }{D}[/tex]

Therefore -

x = 120/4 = 30

y = 20/4 = 5

z = 40/4 = 10

Hence, the cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.
