Answers

Answer 1

Answer:

v= 13

w= -32

Step-by-step explanation:

2v+6w=-36

5v+2w=1

2w= 1-5v

2v+ (3)(1-5v)= -36

2v+3-15v= -36

3-13v =-36

3--36= 13v

39= 13v

13 = V

5×13+2w=1

65+2w=1

1-65= 2w

-64=2w

-32=w

The wheels on Kevin’s bike have a diameter of about 3 feet. How far does the bike travel in 12 complete rotations? (Use 3.14 to represent pi)

Answers

Answer:

113.04 feet

Step-by-step explanation:

Use circumference formula to find one rotation:

C = 2πr = πdC = 3.14*3= 9.42 feet

Full travel of 12 rotations:

12*9.42 = 113.04 feet

Use circumference formula to find one rotation:

C = 2πr = πd

C = 3.14*3= 9.42 feet

Full travel of 12 rotations:

12*9.42 = 113.04 feet Ans.

Ben bought 19 first class stamps at $0.39 each and 8 postcard stamps at $0.24 each. How much money did Ben spend?

Answers

Answer:

Ben spent $9.32 on stamps total

Step-by-step explanation:

19x0.39= 7.41 because it says he bought 19 of these and they each cost $0.39 so you just multiply the two

8x0.24= 1.92 because of the same reason for the other it says he bought 8 of these and each costs $0.24 so you just multiply the two which gets you 1.92

next you add together the two totals of the stamps which is 7.41 and 1.92

7.41+1.92= 9.32

Which 01 the following options best describes the zeros of the quadratic function above?
0) Imaginary zeros
() 2 real zeros
1 real zero and 1 Imaginary zero
f 1 real zero

Answers

Answer:

Option (1)

Step-by-step explanation:

Vertex form of the quadratic equation is given by,

y = (x - h)² + k

Where (h, k) is the vertex.

From the graph attached,

Vertex of the parabola is (0, 4).

Therefore, equation of the parabola will be,

y = (x - 0)² + 4

y = x² + 4

Function representing the parabola will be,

f(x) = x² + 4

For the zeros of the quadratic function we find the value of x where f(x) = 0.

x² + 4 = 0

x² = -4

x = ±√(-4)

Since, square root of a negative number is not defined, zeros of the function will be imaginary.

Therefore, both the zeros will be imaginary.

It's clear from the graph, there are no x intercepts of the function Or zeros are imaginary.

Option (1) will be the answer.

Francesca had 32 cups of flour. She used 3/8 of the flour for a recipe how much flour did Francesca used

Answers

She used 12 cups of flour.

Make a proportion to where 8/8 equals 32.
3/8 equals ?/32
Then cross multiply and divide.
32 x 3 = 96
96/8 = 12

You can also think of it like this. What number times 8 will get you 32?
Well that’s 4.
So 3 x 4 = 12
Since they are proportions of each other what the bottom is multiplied the top must be as well

what is the factored form of -40+2×^2-2x

Answers

Answer:

2(x - 5)(x + 4)

Step-by-step explanation:

Given

- 40 + 2x² - 2x , that is

2x² - 2x - 40 ← factor out 2 from each term

= 2(x² - x - 20) ← factorise the quadratic

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)

The factors are - 5 and + 4 , since

- 5 × 4 = - 20 and - 5 + 4 = - 1 , then

x² - x - 20 = (x - 5)(x + 4) and

2x² - 2x - 40 = 2(x - 5)(x + 4) ← in factored form

Solve the equation for b 4a + 6c – 2b = 12 .

Answers

Answer:

b=2a+3c−6

Step-by-step explanation:

Let's solve for b.

4a+6c−2b=12

Step 1: Add -4a to both sides.

4a−2b+6c+−4a=12+−4a

−2b+6c=−4a+12

Step 2: Add -6c to both sides.

−2b+6c+−6c=−4a+12+−6c

−2b=−4a−6c+12

Step 3: Divide both sides by -2.

−2b

−2

−4a−6c+12

b=2a+3c−6

Answer:

b=2a+3c−6

Which of these statements is true for f(x)=(1/10)^x
A. The domain of f(x) is x > 0.
B. The graph contains (1)
C. It is always increasing.
D. The range of f(x) is y

Answers

Answer:it’s B trust me

Step-by-step explanation:

Statemen B is true about the given function.

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

A. The domain of f(x) is x > 0 is true for the function [tex]f(x) = (1/10)^x[/tex] because any positive real number can be raised to any real power, so the domain of this function is all real numbers greater than zero.

B. The statement "The graph contains (1)" is not clear. If it means whether the point (1, f(1)) lies on the graph, then we can find that [tex]f(1) = (1/10)^1 = 1/10[/tex], so the point (1, 1/10) lies on the graph. Therefore, the statement is true.

C. The function [tex]f(x) = (1/10)^x[/tex] is always decreasing because as x increases, [tex]f(x) = (1/10)^x[/tex] becomes smaller and smaller, approaching zero as x approaches infinity.

D. The range of f(x) is y < 1 because as x increases, [tex](1/10)^x[/tex] becomes smaller and smaller, approaching zero but never equaling one. So, the range of the function is all real numbers less than one, but not including one itself.

What is the implication, hypothesis and conclusion in this statement all engineers are resourceful.

Answers

Answer:

The majority of theorems in mathematics take the form of compound statements. These statements are called conditional and biconditional statements.

The conditional statement from the sentence above is:

If x is an engineer then x is resourceful.

Put in a mathematical form we can refer to the Implication as:

If Xe then R. Or

Xe implies R. Or

Xe if R.

The Hypothesis is stated as

Xe ⇒ R

The statement Xe in an implication Xe ⇒ R is called its hypothesis, premise, or antecedent, and R the conclusion or consequence.

Implications are critical in expressing a logical argument. If an implication is found to be true, then the consequences must be as well when the hypothesis satisfied. This is why is also referred to as a conditional statement.

Given triangle ABC and a point D on the side AC. Suppose AB=6, BC=8, AC=9, and AD=4. Find BD

Answers

Answer:

BD = 5 1/3

Step-by-step explanation:

Triangle ABD and ACB are similar with angle A = angle A, angle ABD = ACB. Similar by AA. AB:AC = 6:9, AD:AB = 4:6. This means that the ratio of triangle ABD : ACB is 1 : 1.5. Because of this, since BD corresponds to BC, then BD : 8 = 1 : 1.5, and BD = 8 divided by 1.5, so BD = 5 1/3
