B.False​

The Polynomial Below Is A Perfect Square Trinomial Of The Form A2 - 2AB + B2.9x^2-36x+16A.TrueB.False

Answers

Answer 1

Step-by-step explanation:

9x² - 36x + 16

= (Ax - B)² = A²x² - 2ABx + B².

By Comparing Coefficients, we have:

A² = 9,

2AB = 36,

B² = 16.

It is obvious that A = 3 and B = 4.

However 2AB = 2(3)(4) = 24 which is not equal to 36.

Hence 9x² - 36x + 16 is not a perfect square trinomial.

Answer 2

Answer:

False

Step-by-step explanation:

The polynomial cannot be factored.

what's the inequality describes all possible length of AB?

Answers

Answer:

We conclude that inequality describes all possible lengths of AB

13 < x < 35

Option C is true.

Step-by-step explanation:

We know that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Now, checking the interval of the length of the side 'x', such as:

24 + 11 = 35

24 - 11 = 13

so the possible lengths of the side 'x' will be:

13 < x < 35

Therefore, we conclude that inequality describes all possible lengths of AB

13 < x < 35

Hence, option C is true.

What is the lowest common denominator of 1/32 and 2/3

Answers

Answer:

96

Step-by-step explanation:

The least common denominator or lowest common denominator is the smallest multiple that the denominator (that is the number on the bottom of a fraction) has in common.

Since 32, and 3 have no common factors, one simply has to multiply them to find the least common denominator.

32 * 3 = 96

in triangle DEF, DE=EF and G is the midpoint of EF. if the measure of GDE=10 what is the measure of E?

Answers

Note: It seems you may have forgotten to attach the diagram. Hence, I am attaching the potential diagram of your question.

Answer:

The measure of angle E is:

m∠E = 80°

Step-by-step explanation:

Given

The triangle ΔDEF

m∠GDE = 10°

DE = EF

G = midpoint of EF

To Determine

m∠E =?

Solving

As DE=EF and G is the midpoint of EF.

It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.

So, the right angle G is m∠DGE = 90°

as

m∠GDE = 10° m∠DGE = 90° m∠E = ?

We know that the sum of angles of a triangle is 180°.

m∠GDE + m∠DGE  + m∠E = 180°

10° + 90° + m∠E = 180°

m∠E = 180°  - 10 - 90

m∠E = 80°

Therefore, we conclude that the measure of angle E is:

m∠E = 80°

Admission to the local amusement park cost $5.25 and each ride cost $2.50 which of the following equations represents the cost C in dollars for admission to the park with ex ride tickets?

Answers

Answer:

C=2.50r+5.25

Step-by-step explanation:

(r represents each ride cost)

5.25 would be the y-intercept since that's the initial fee to enter the park, and 2.50 would be the slope since each ride would cost that much.

5.25+2.5x=c (cost) x is how many rides

What is the surface area of the cuboid 3cm 5cm and 2cm.

Answers

Answer:

SA = 62 cm2

Step-by-step explanation:

The surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.

What is the formula for the total surface area of a cuboid?

The total surface of the cuboid = 2(LB+BH+HL)

Consider that the length, width, and height of the cuboid are L, B, and H.

The cuboid is given in the question

Which has the length, width, and height of the cuboid are 3 cm, 5 cm, and 2 cm.

The surface area of the cuboid = 2(LB+BH+HL)

Here L = 3 cm, B = 5 cm, and H = 2 cm

Substitute the values in the above formula, and we get

The surface area of the cuboid = 2(3 × 5 + 5 × 2  + 2 × 3)

The surface area of the cuboid = 2(15 + 10 + 6)

The surface area of the cuboid = 2(31)

The surface area of the cuboid = 62 cm²

Thus, the surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.

Is -8 - 2(3 + 2x) + 7x equivalent to -30 -13x?

Answers

Answer:

They are NOT equivalent.

Step-by-step explanation:

To find if the expressions are equivalent, we have to simplify the first expression.

Solve:

-8 - 2(3 + 2x) + 7x

Use the distributive property.

-8 - 6 - 4x + 7x

Combine like terms.

-14 - 4x + 7x

-14 + 3x

Since they're not the same, this means that the expressions are NOT equivalent to each other.

The probability that a women likes the color blue is 10%. The probability of being a women is 40%.What is the probability that a person likes the color blue given that they are a woman?​

Answers

Answer:

The probability that a person likes the color blue given that they are a woman=0.25%

Step-by-step explanation:

We are given that

The probability that a women likes the color blue=10%=[tex]\frac{10}{100}=0.1[/tex]

The probability of being a women=40%=[tex]\frac{40}{100}=0.4[/tex]

We have to find the probability that a person likes the color blue given that they are a woman.

We know that

Conditional probability formula

[tex]P(A/B)=\frac{P(A\cap B)}{P(B)}[/tex]

The probability that a person likes the color blue given that they are a woman

=[tex]\frac{0.1}{0.4}[/tex]

[tex]=\frac{1}{4}=0.25[/tex]

Hence, the probability that a person likes the color blue given that they are a woman=0.25%

The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. a) You watch a roulette wheel spin 7 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin

Answers

Answer:

9 / 19

Step-by-step explanation:

Given that:

Number of slots on roulette wheel = 38

Number of red on wheel = 18

Number of black on wheel = 18

Number of green = 2

The probability that ball will land on red slot :

Recall: probability of event (A) = P(A)

P(A) = (number of required outcome / number of total possible outcomes)

Hence,

P(ball lands on red) = (Number of red slots / total number of slots)

P(ball lands on red) = 18 / 38

P(ball lands on red) = 9/ 19

A box of 10 flashbulbs contains 2 defective bulbs. A random sample of 2 is selected and tested. Let x be the random variable associated with the number of defective bulbs in the samplea. find the probability distribution of Xb. find the expected number of defective bulbs in a sample

Answers

Step-by-step explanation:

The probability of selecting no bad ones is the probability of

selecting 2 from the 8 good bulbs, which is C(8,2)/C(10,2) or it can also be written as  (8C2)/(10C2) = 28/45

The probability of selecting 1 good one and one bad one, is the

probability of selecting 1 from the 8 good bulbs, and one from

the 2 bad ones, which is [C(8,1)C(2,1)]/C(10,2) or as some people

write it (8C1×2C1)/(10C2) = 16/45.

The probability of selecting two bad one, is C(2,2)/C(10,2) or

as some people write it (2C2)/(10C2) = 1/45.

Line segment AB has a length of 1 unit. It is translated 4 units to the right on a
coordinate plane to obtain line segment A'B'. What is the length of A'B'?

Answers

Answer:

1 unit

Explanation:

We know that line segment AB is 1 unit long, and that it is translated 4 units to the right to obtain line segment A'B'. A translation is a type of rigid transformation - which means that the shape stays the same as it is moved on a coordinate plane. Therefore, the length of line segment A'B' would be the same as line segment AB: 1 unit.

b)
Write the amount of girls in the class as a fraction in its simplest form.

Answers

Answer:

Boys: 1/3

Girls: 2/3

Step-by-step explanation:

There are 8 boys in the class out of 24 students.

The fraction will be 8/24. Both the numerator and the denominator are divisible by 8.

8 ÷ 8 = 1

24 ÷ 8 = 3

The simplest form will be 1/3.

There are 16 girls in the class because 24 - 8 = 16.

The fraction will be 16/24. Both numbers are divisible by 8.

16 ÷ 8 = 2

24 ÷ 8 = 3

The simplest form will be 2/3.
