Answers

The given sequence is
[tex]a_{1}=2 \\ a_{n+1}=-4a_{n}+2[/tex]

Write the first 4 terms.
When n=1, obtain
a₁ = 2
When n=2, obtain
a₂ = -4a₁ + 2
= -4(2) + 2 = -8 + 2
= -6
When n=3, obtain
a₃ = -4a₂ + 2
= -4(-6) + 2 = 24 + 2
= 26
When n=4, obtain
a₄ = -4a₃ + 2
= -4(26) + 2 = -104 + 2

Angie has laid out a design for a garden consisting of two triangular areas as shown. The points are A (0,0), B (0,5), C(3,5), D(6,5), E(6,0). Name the type of congruence transformation for the preimage ABC to EDC.

A.) reflection
B.) rotation
C.) translation
D.) none of these

Answers

I think the correct answer would be A. The type of congruence transformation for the preimage ABC to EDC would be a reflection. It is a transformation where you basically flip the preimage or the original shape ove a line which is called the line of reflection. So, the image would be a mirror image of the preimage. By plotting the points, you will see that triangle EDC is just a mirror image of triangle ABC and the line of reflection would be at x = 3. It could not be a rotation since the preimage was not turned or rotated around a center of rotation. Also, it cannot be a translation since the preimage was not just moved left, right, up or down.

Chase answers 3/4 of his math questions correctly. There were 40 questions on the test.

a. How many did he get right?

b. How many did he miss?

Answers

Since there were 40 questions on a math quiz and he got 3/4 correct he got 30 correct and 10 incorrect.
A simple way to solve this is to add a zero to the end of each number in the fraction since there is 40 questions so it goes from 3/4 correct to 30/40 correct.
Hope this helps!!

Final answer:

Chase answered 30 questions correctly and missed 10 questions.

Explanation:

To find the number of questions Chase got right, multiply the fraction of questions answered correctly (3/4) by the total number of questions (40):

Number of questions answered correctly = (3/4) * 40 = 30

To find the number of questions Chase missed, subtract the number of questions he got right from the total number of questions:

Number of questions missed = 40 - 30 = 10

Misha used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below: Color of Marble Number of Times Rolled Blue 20 Green 18 Yellow 12 Heads Tails 28 22 Using Misha's simulation, what is the probability of pulling a blue marble and the coin landing tails up?

Answers

To solve this problem, let us first remember that probability is:

Probability = number of successful events / number of total events

Now, let us first calculate the probability of getting a blue marble. There are 20 blue marbles out of 50 total marbles, therefore the probability is:

P (blue marble) = 20 / 50 = 0.4

Next, let us calculate for the probability of landing tails up. There are 22 tails success out of 50 times the coin was tossed, therefore the probability is:

P (tails) = 22 / 50 = 0.44

Finally, since we want to find the Probability of getting blue and Probability of landing tails, we multiply the two:

P (blue and tails) = 0.4 * 0.44

P (blue and tails) = 0.176 (ANSWER)

Now if the choices are in fraction:

P (blue and tails) = (20 / 50) (22 / 50) = 440 / 2500

Answer:

The answer is 440/2500

Two right triangles are attached along their longest side. The smaller triangle has height 6 cm and base 2 cm. The height of the larger triangle is 7 cm, and its base is 3 cm.

Answers

The formula to find area of a triangle is (base × height) ÷ 2

You have to find a way to eliminate either x and y. We'll eliminate x:

2x + 3y = -5
3x - 5y = 21

2x*3 + 3y*3 = -5*3
3x*-2 + -5y*-2 = 21*-2

Which expression could be used to determine the product of –4 and 3 1/4?

Answers

Final answer:

To determine the product of -4 and 3 1/4, multiply the whole numbers and the fractions separately, and then add the results together.

Explanation:

The product of -4 and 3 1/4 can be determined by multiplying the whole number part, -4, by the whole number part of the mixed number, 3, and then multiplying the fraction part, 1/4, by the whole number part of the mixed number and adding the result to the previous product.

So, -4 × 3 = -12

and (-4) × (1/4) = -1

Therefore, the product of -4 and 3 1/4 is -12 - 1/4 = -12 1/4.

Final answer:

To find the product of -4 and 3 1/4, convert the mixed number to an improper fraction and then multiply.

Explanation:

The product of -4 and 3 1/4 can be found using the expression:

-4 x 3 1/4

To multiply a whole number by a mixed number, you can convert the mixed number into an improper fraction and then multiply:

-4 x 13/4

Multiplying whole numbers and fractions can be done by multiplying the numerators and denominators separately:

-4 x 13 = -52

4 x 1 = 4

The final answer is -52/4, which simplifies to -13.

winston's soup recipe make 6 servings and uses 4 carrots and 2 potatoes. how many will winston need for 15 servings

Answers

Hello there!
We have the following equation:
c + p = 15 (c = carrots, p = potatoes)
Previously, we had this equation:
2 + 4 = 6.
2 is 1/3 of 6, and 4 is 2/3 of 6. The sum of these two fractions make a whole.

Let's apply this rule to 15 servings.
Since we are looking for thirds, divide 15 by 3 to solve for 1/3, or "p".
15 / 3 = 5
We have 5 potatoes.

Now, we must remember that the amount of carrots is twice the amount of potatoes.
Divide 15 by 3, then multiply that quotient by 2.
15 / 3 = 5
5 * 2 = 10

We have 10 carrots.

Your final answer is:
Winston will need 5 potatoes and 10 carrots.

You need to cut a 9 foot piece of plywood into 12 inch sections. Every cut also removes 1/8 inch. How much of the plywood will be left after cutting the 12 inch sections?

Answers

There are 9 feet so it would usually be nine 12" pieces but since each cut takes away 1/8, you can only cut 8 pieces equal to 12 inches.

Considering this fact, each cut would take away 0.125 inches. If you're cutting 8 times, you would in all be taking away 1 inch.

So aside from the eight 12" sections, you would have a leftover of 11 inches.

11 inches of the plywood will be left after cutting the 12 inch sections.

What is Fraction?

A fraction represents a part of a whole.

Given that we need to cut a 9 foot piece of plywood into 12 inch sections and every cut also removes 1/8 inch.

We are to find the quantity of plywood that will be left after cutting the 12 inch section.

We know that 1 foot = 12 inches.

So, 9 foot = 12 × 9 = 108 inches.

Since each cut removes 1/8 inch at ever cut, so the number of 12 inch sections will be 8.

Quantity of plywood that remained after cutting the 12 inch sections will be 108-12×8-8×1/8=11

Hence, 11 inches of the plywood will be left after cutting the 12 inch sections.
