The Sunday school teacher gave 5 Friend's Day invations to each of her 19 students to give to their friends. She had 5 left over. How much invations did the teacher start out with?

Answers

Answer 1

I'm pretty sure its 100 because if she gave each of her 19 students 5 invitations that equals 95. (19×5=95) And She had 5 leftover equals 100. (95+5=100)

Answers

Answer:

2d^2

-15c^4

-10c^2 d

3c^2d

Step-by-step explanation:

Just had the question, good luck lovelies! :)

The partial products for the expression (3c² + 2d)(-5c² + d) are -15c⁴, 3c²d, -10c²d, and 2d².

The multiplication of the expression (3c² + 2d)(-5c² + d) step by step,

(3c² + 2d)(-5c² + d)

To find the partial products, we'll use the distributive property, which states that for any numbers a, b, and c:

a(b + c) = ab + ac

Now, applying this to your expression:

3c² × -5c²:

Multiply 3c² by -5c².

Result: -15c⁴

3c² × d:

Multiply 3c² by d.

Result: 3c²d

2d × -5c²:

Multiply 2d by -5c².

Result: -10c²d

2d × d:

Multiply 2d by d.

Result: 2d²

Therefore, these are the partial products obtained when multiplying the given expressions.

Which of these is equal to sin 21°?
A) cos 21°
B) cos 69°
C) sin 69°
D) tan 69°

Answers

Answer: Choice B) cos(69)

Work Shown:
cos(90-x) = sin(x)
cos(90-21) = sin(21)
cos(69) = sin(21)

Answer:

B. Cos 69°

Step-by-step explanation:

Given : sin 21°

Solution : To show how Cos 69 ° = Sin 21 °

we will use sine and cosine trigonometric identity

i.e. Cos (90 °-x) = Sin x ---(A)

We are given Sin 21 °

So, putting x =21 ° in (A)

We are getting : Cos(90 °-21 °) = Sin 21 °

⇒Cos 69 ° = Sin 21 °

Hence it is shown that Cos 69 ° = Sin 21 °

Graph the function f(x)= square root over x. Which table of values contains points that lie on the graph of the function?

Answers

Answer:

see attached

Step-by-step explanation:

The square root of a negative number is undefined, so the applicable table is the one shown below.

Answer:

Table 3 represents the correct points that lie on the graph of the function.

Step-by-step explanation:

We are given the function:

[tex]f(x) = \sqrt{x}[/tex]

We have to plot the given function.

The attached image shows the graph for the given function.

Putting values for x in the function we get:

[tex]f(x) = \sqrt{x}\\f(-1) = \sqrt{-1}[/tex]

which is undefined.

[tex]f(0) = \sqrt{0} = 0\\f(1) = \sqrt{1} = 1[/tex]

Determine if the graph of r = 4cos 5θ is symmetric about the x-axis, the y-axis, or the origin.

Answers

Answer:

y-axis

Step-by-step explanation:

The function graph is symmetric about

- the y-axis when it is an even function

- the origin when it is an odd function.

A symmetrical graph about the x-axis is not a function graph.

f(x) is an even if and only if f(-x) = f(x).

f(x) is an odd if and only if f(-x) = -f(x).

We have the function r(θ) = 4cos(5θ)

(olny symmetry about the y-axis or about the origin)

Check r(-θ):

r(-θ) = 4cos(5(-θ)) = 4cos(-5θ) = 4cos(5θ)

used cos(-x) = cos x

We have r(-θ) = r(θ). Therefore the graph of r(θ) is symmetric about the y-axis.

Answer:

x-axis

Step-by-step explanation:

if r%28theta%29+=+r%28-theta%29.

Since 4cos%285%2Atheta%29+=+4cos%28-5%2Atheta%29, the graph is symmetric wrt the x-axis.

The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi-theta%29.

Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+-+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the y-axis.

The graph is symmetric wrt the y-axis if r%28theta%29+=+r%28pi%2Btheta%29.

Since 4cos%285%2Atheta%29+%3C%3E+4cos%285%2A%28pi+%2B+theta%29%29+=+-4cos%285%2Atheta%29+, the graph is not symmetric wrt the origin.

Hope this helps :D

Answer:

The correct option is 4.

Step-by-step explanation:

Given information: K is the center of the circle. AB is the diameter of the circle.

Angle subtended by a diameter is always a right angle. It the means the measure of that angel is 90 degree.

[tex]\angle C=90^{\circ}[/tex]

According to the angle sum property, the sum of interior angles of a triangle is 180 degree.

Using angle sum property in triangle ABC, we get

[tex]\angle A+\angle B+\angle C=180^{\circ}[/tex]

[tex]75^{\circ}+x+90^{\circ}=180^{\circ}[/tex]

[tex]x=15^{\circ}[/tex]

Therefore the measure of x is 15 degree. Option 4 is correct.

In the xy-plane, if (-1, 0) is a solution to the system of inequalities y < x + c and y < -x - d, which of the following must be true about c and d? (10 POINTS + BRAINLIEST ANSWER!!)

A. c = d

B. c = -d

C. c < d

D. d < c

Answers

Final answer:

By substituting the point (-1, 0) into the inequalities, we find that c must be greater than 1, and d must be less than 1, which means the correct answer is D. d < c.

Explanation:

We are given a point (-1, 0) which is a solution to both inequalities y < x + c and y < -x - d. To find the relationship between c and d, let's plug in the x and y values of the point into each inequality.

For y < x + c, with x = -1 and y = 0, we get:

0 < -1 + c

c > 1. (1)

For y < -x - d, with x = -1 and y = 0, we get:

0 < 1 - d

d < 1. (2)

Comparing (1) and (2), we see that c must be greater than 1 and d must be less than 1. Thus, the correct answer is D. d < c.

Terry just bought a used car with only 28,500 miles on it and it cost $8,200. Every year Terry expects to put another 14,000 miles on the car. Unfortunately, the car’s value will depreciate by 15% per year. How much will the car be worth when it has 100,000 miles on it? Explain your work.

Answers

It will take (100 -28.5)/14 ≈ 5.107 years to get to 100,000 miles. In that time the car will depreciate by a factor of 0.85^5.107, about 0.43605. The value at that time will be
.. $8200*0.43605 ≈ $3706

_____
The difference between 100k miles and 28.5k miles is 71.5k miles. It is "used up" at the rate of 14k miles per year, so the time it takes to do that is 71.5/14 ≈ 5.1 years.

Each year the car depreciates 15%. That is, its value is multiplied by 1 -15% = 0.85. In 5.1 years, the original value will be multiplied by 0.85^5.1. (Remember, exponentiation is repeated multiplication.)

Answer: The simplest form of the ratio would be 50:13.

If we use the values in the problem, we have a ratio of 1:0.26. The problem is that we have a decimal value and we should use whole numbers.

Start by multiplying each value by 100 to eliminate the decimal.

We have 100:26.

Note that -40 = -8 * 5 and -8 + 5 = -3 ( the 'middle' number in the standard form)
