Answer: C  (0,1)

Step-by-step explanation:

The y intercept of a function is when it's x coordinate is zero, so input 0 into the function and solve for f(x)

f(0) = (1/2)^x  

f(0) = (1/2)^0

f(0) = 1     Any number raised to zero is 1  so the y intercept has to be 1.

Answer:

0.1

Step-by-step explanation:

Solving using empirical rule formula

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

Hence, the lower bound 95% =

μ - 2σ

Mean = 0.2

Standard deviation of 0.05

= μ - 2σ

= 0.2 - 2(0.05)

= 0.2 - 0.1

= 0.1

The lower bound is 0.1

Answer:

242880

Step-by-step explanation:

In the English alphabet, we have 5 vowels. To form a string of 5 English letters in which it starts with two consecutive vowels; then we have the following.

In the first space, 5 vowels are possible.

in the second space, 4 vowels are possible since there is no room for repetition of letters.

Now, the total number of ways of assigning two distinct vowels in the first two spaces = 5 × 4 = 20

From the question, since it is said that the letter starts with two consecutive vowels, it implies that starting from the third letter, it can be filled with all the remaining alphabet, be it a vowel or consonant.

Thus, the remaining alphabet = 26 - 2 = 24 alphabets to fill the 3 remaining spaces, which can be achieved in 24P3 ways.

P(24,3) = 24!/(24-3)!

P(24,3) = 24!/21!

P(24,3) = 24 × 23 × 22 × 21! / 21!

P(24,3) = 24 × 23 × 22

P(24,3) = 12144 ways

Thus, the total number of strings of five  English letters that start with two consecutive vowels without having repeated letters is:

= 5  × 4  ×  24 × 23 × 22

= 242880

 5        4        24          23       22  

Answer:

Rotation about the origin only changes the coordinates but angle or segment measures remain same, therefore parallel and perpendicular lines stay as is.

Answer:

5 is congruent by HL this is because  both have a right angle and a congruent side

6 you do not have enough information.

Answer:

16/81

Step-by-step explanation:

Given the expression, 81y'' = -16y where y = coskt,

We want to know the value of k that satisfies the expression

y' = -ksinkt

y" = -k²coskt

Substitute y and y" into the expression given;

81y'' = -16y

81(-k²coskt) = -16(kcoskt)

-81k = -16

Divide both sides by -81

-81k/-81 = -16/-81

k = 16/81

Hence the value of k is 16/81

Answer: (-5,35)

Substitute into y=-7x

Y=-7(-5)

Simplify

Y=35

Answer:

Mathematical beauty is the aesthetic pleasure typically derived from the abstractness, purity, simplicity, depth or orderliness of mathematics.[1] Mathematicians often express this pleasure by describing mathematics (or, at least, some aspect of mathematics) as beautiful. They might also describe mathematics as an art form (e.g., a position taken by G. H. Hardy[2]) or, at a minimum, as a creative activity. Comparisons are often made with music and poetry.

Step-by-step explanation:

Use the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Answer:

16 1/4 or 65/4

Step-by-step explanation:

Answer:

it is equal to the fraction 1625/10 or 325/2

Answer:

Step-by-step explanation:

a. 3-4x=-7-4x

3=-7. no solution

b. 15 - 2x = -7x

15 = -5x

x=-3. one solution

c. 7y-21=6y-21

y=0

1. -3x+4=-3x+7

4=7

2. 10+2x = 5x+2

8=3x

x=3/8

3. x+5=x+5

Answer:

Step-by-step explanation:

a) 3 - 4x = -7 - 4x

- 4x in both terms can be cancelled

3 = -7 ⇒ equation with no solution

b) 15 - 2x = -7x

15 = -5x

-3 = x

x = -3

c) 7 (y - 3) = 6y - 21

7y - 21 = 6y - 21

7y - 6y = -21 + 21

y = 0

1) Equation with no solution:

3x + 5 = 12 + 3x

there is no x that conforms that equation because the result is always 5 = 12, which is inconsistent

2) Equation with one solution

2y -5 = 7   ⇒ y = 12/2  ⇒ y = 6

3) Equation with infinite solutions

x - 10 = x - 3 - 7

Any value of x complies with this equation

Answers

1. x=7

2. x=6

3. x=9

4. x=8

Explanations

1. This is an isosceles triangle because two angles are congruent. This also means the two sides are the same. This means  7 = x.

2. This is an equilateral triangle because all the angles are the same. Therefore, all sides are also the same. So x = 6.

3. This is also an equilateral triangle. We know this because all sides are the same. So from this we know that x-3 = 6. Solve the equation, and you'll find that x = 3.

4. This is also an isosceles triangle, because two of the angles are congruent. This means 2x-9 = 7. Solve this equation; x=8

Answer:

27) x = 7

28) x = 6

29) x = 9

30) x = 7

Step-by-step explanation:

I first added to two angles we already knew. Then, I took that number and subtracted it from the whole number in the algebraic equation. I then divided that number with the value paired with x to get x.

Answer:

A. SSS

Step-by-step explanation:

∆ABC has shown above has two given sides indicated, AB and AC, which are congruent to the corresponding two sides l, DC and DB, of ∆DCB.

Also, their third side is also congruent since they share a common side, side BC.

This means that the three sides of ∆ABC is congruent to the three corresponding sides of ∆DCB.

Therefore, ∆ABC is congruent to ∆DCB by the Side-Side-Side Congruence Theorem, which holds that of the three sides of one triangle is congruent to the three corresponding sides of another, then both ∆s are congruent.

Answer: C, 12 units on edge

Step-by-step explanation:

Answer:

11cm = diameter.

c=circumference

d=diameter

π=3.14

r=half of diameter

34.56

C=2πr

d=2r

Solving for d (diameter)

d=C

π=34.56

π≈11.00079cm

rounded = 11cm!

You promised brainlest! Please!!

Step-by-step explanation:

Answer:

11.0008

Step-by-step explanation:

“Since we know circumference and diameter are related by π, we can use π to find diameter if we know circumference”

Equations:

C = πd

C/π = d

Therefore:

34.56 = pi(d)

34.56/3.14159265359 = 11.000789..........
