What is the length of the arc by a central angle of 85 degrees and a radius of 8cm to the nearest tenth of a cm?

Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2

Explanation:

The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.

Step-by-step explanation:

[tex]2. \: a. \: \sqrt[3]{ - 1} [/tex]

[tex] = \sqrt[3]{( - 1 )\times ( - 1 )\times( - 1)} [/tex]

= -1 (Ans)

[tex]b. \: \sqrt[3]{ - \frac{8}{27} } [/tex]

Since,

[tex] \sqrt[3]{ - x} = - \sqrt[3]{x} [/tex]

Hence,

[tex] = - \sqrt[3]{ \frac{8}{27} } [/tex]

[tex] = - \sqrt[3]{ \frac{2 \times 2 \times 2}{3 \times 3 \times 3} } [/tex]

[tex] = - \frac{2}{3} (ans)[/tex]

[tex]3. \: a. \: 10 - 2 \sqrt{9} [/tex]

[tex] = 10 - 2 \sqrt{3 \times 3} [/tex]

= 10 - 2 × 3

= 10 - 6

= 4 (Ans)

[tex]b. \: 70 - {( \sqrt[3]{64} )}^{3} [/tex]

[tex] = 70 - \sqrt[3]{ {64}^{3} } [/tex]

[tex] = 70 - \sqrt[3]{64 \times 64 \times 64} [/tex]

= 70 - 64

Answer: A. 117,600 people.

Answer:

Its 119,318

Step-by-step example:

subtract 100 from 12 you get 88 then do 88% of 119,318, you get 104,999.84. Round 104,999.84 up and you get 105,000.

Answer:

Dependent Events

Step-by-step explanation:

Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.

If the first ball is chosen the probability will 1/3  leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3.  In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.

In this the events are called dependent events.

Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.

Answer:

$41.04

Step-by-step explanation:

8% = 0.08

38(0.08) = 3.04

$3.04 is the tax for the jeans. Now we just have to add it to the price.

38 + 3.04 = $41.04

Answer:

$41.04

Step-by-step explanation:

0.08 (the tax converted from percentage) x 38 (initial cost) = 3.04(tax amount)

38(initial amount) + tax amount (3.04) = 41.04

the cost after tax is $41.04

understand now? To convert 8% to a decimal just move the decimal to the left twice (because we’re representing out of 100%)

Answer:

(x-3)

Step-by-step explanation:

2x²+5x-3=x² +x−6x−3 =x(2x+1)-3(2x+1) =(2x+1)(x-3)

The required missing factor is (x - 3).

Given the equation, 2[tex]x^2[/tex] + 5x - 3 = (2x - 1).

To find the missing factor in the equation 2x^2 + 5x - 3 = (2x - 1), to factorize the quadratic equation on the left side and compare it to the given factor (2x - 1).

The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.

To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to

2[tex]x^2[/tex] + 5x - 3.

To determine the values of a, b, c, and d, we can use the FOIL method (First, Outer, Inner, Last). FOIL involves multiplying the first terms, the outer terms, the inner terms, and the last terms of the two binomials.

Factorize the quadratic equation:

2[tex]x^2[/tex] + 5x - 3

(2x - 1)(cx + d) = 2[tex]x^2[/tex] + 5x - 3

Expanding the left side using FOIL:

(2x - 1)(cx + d) = 2[tex]x^2[/tex] + 6x - x - 3

Combining like terms on the right side:

(2x - 1)(cx + d) = 2x( x  -  3) -1 (x - 3)

Combining like terms on the right side:

(2x - 1)(cx + d) = (2x - 1)(x - 3)

By comparing the coefficients of the terms on both sides of the equation, determine the missing factor. Observe that the coefficient of x^2 is 2 on both sides, and the coefficient of x is -1 on both sides.

Therefore, the missing factor is (x - 3).

Hence, the complete factorization of the quadratic equation

2[tex]x^2[/tex] + 5x - 3 = (2x - 1)(x - 3).
