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

= 6 (Ans)

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.

Step-by-step explanation:

f(x) is (0,+inf)

Answer: (x,y) has the meaning of plane's point coordinates. The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi.

Step-by-step explanation:

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.

Answer:

d, the number of degrees that the temperature was lowered by

Step-by-step explanation:

The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.

Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.                         2 ways to find the area of a triangle using Pythagorean Theorem? 1. Using Pythagorean theorem. The basic formula for triangle area is side a (base) times the height h , divided by 2: area = (a * h) / 2 2.Using trigonometry. Let's start from the trigonometric triangle area formula: area = (1/2) * a * b * sin(γ) , where γ is the angle between sides.

Answer:

Step-by-step explanation:

Answer:

x:(−3+26−−√,0)≈(2.09901951359278,0),(−26−−√−3,0)≈(−8.09901951359278,0).

y:(0,-17)

Step-by-step explanation:

find the focus, axis of symmetry, eccentricity, latus rectum, length of the latus rectum, vertex, directrix, focal parameter, x-intercepts, and y-intercepts of the parabola y=x2+6x−17.

lets do this step by step.

First: we need to break this into to prisms.

Next lets say the dimensions:

4 x 2 x 1 and 2 x 2 x 1

now we multiply them and then add them

8 + 4 = 12

volume = 12 cubic units.

Answer:answer is D

Step-by-step explanation:

Answer: -39

Step-by-step explanation:

Hope this helps.

Answer:

Step-by-step explanation:

V=πr^2h is the equation for volume of a cylinder.

the radius is half of 50 so 50/2=25.

then 75 is the height so you plug the vaules in

V=(3.14)((25)^2)(75)

then multiply and you get 147187.5 rounded to the nearest whole number that is 147188

hope this helps :)

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).

Surface Area: 94 ft

Volume: 60 ft

Answer:

A. 10 ft

Step-by-step explanation:

Since dimensions of the wall are similar to the dimensions of the window.

Therefore, lengths and widths of wall and window would be in proportion.

So,
