Answer:

[tex]\boxed{\mathrm{Option \;D: 5x^4-37x^3-6x^2+41x-6}}[/tex]

Step-by-step explanation:

You can solve such multiple choice questions using a trick. This especially is useful in a time constrained question

Consider only the coefficients of the terms relating to x⁴ and the constant

If you expand (-4x³ + 5x - 1)(2x - 7) this will work out to

(--4x³) (2x) +..... + (-1)(-7)

This will result in (- 8x⁴ +..... + 7)

Since there is a negative sign before this last term, expanding will change the signs of the terms

-(-8x⁴ + ..... + 7) = 8x⁴ -7

Add the coefficients of the x⁴ terms to get

(5 - 8 + 8)x⁴ = 5x⁴

Add the constants of the individual terms

--1 + 2 - 7 which is -6

So the simplified polynomial is of the form

5x⁴ +....... - 6

Only option D fits these values, so the correct choice is Option D:
[tex]\mathrm{5x^4-37x^3-6x^2+41x-6}[/tex]  

ANSWER

--------------------------------------------------------------------------------------------------

If you want to do it the hard way,

First evaluate the last product using FOIL:
[tex]\left(-4x^3+5x-1\right)\left(2x-7\right)\\\\= \left(-4x^3\cdot \:2x-4x^3\left(-7\right)+5x\cdot \:2x+5x\left(-7\right)-1\cdot \:2x-1\cdot \left(-7\right)\right)\\\\= \left(-8x^4+28x^3+10x^2-37x+7\right)\\\\[/tex]

With the negative sign in front of this expression this becomes:

[tex]-\left(-8x^4+28x^3+10x^2-37x+7\right)\\\\= 8x^4-28x^3-10x^2+37x-7\\\\[/tex]

From the original polynomial expression, group like terms:

The distance between the given set of points is 7.8 units.

To find the distance between two points in a coordinate plane, we can use the distance formula.

The distance formula states that the distance between two points (x1, y1) and (x2, y2) is given by the square root of ((x2 - x1)^2 + (y2 - y1)^2).

In this case, we are given the points p(8, 2) and q(3, 8). Therefore, we can plug in the coordinates of these points into the distance formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Distance = √((3 - 8)^2 + (8 - 2)^2)

Distance = √((-5)^2 + 6^2)

Distance = √(25 + 36)

Distance = √61

The square root of 61 is approximately 7.8 which rounded to the nearest tenth is 7.8.

Therefore, The distance between the given set of points is 7.8 units.

Answer:

371 meters

Step-by-step explanation:

This is a triangle trigonometry problem. The phase "angle of depression" means the angle looking down to the boat instead of looking straight out from the top of the tower. See image. You can then find the rest of the angle is 70°. Looking at the boat creates one line, the tower is another side, 135m, and the distance to the boat is the third side of a triangle. See image.

Tangent is a trig ratio. It compares the side opposite from the angle to the side next to (adjacent) the angle. We can then write an equation. Unless the teacher/program/text gives you tan 70°, you need a calculator to find it.

tan 70° = x/135

Multiply both sides by 135.

135 tan 70° = x

Put this in a calculator.

135 × tan70°

it comes out a long decimal. But the directions said to round to the nearest meter.

The boat is about 371 meters away from the foot of the tower.

The assumption we would make to start the indirect proof of AB is congruent to BC is AB + BC.

Indirect Proof: 

Step 1 Suppose a right triangle's hypotenuse is not the longest side. That is BC > AB and AC > AB.

Step 2 If BC > AB, then ∠C < ∠A. Since m C = 90, ∠A > 90. So, ∠C + ∠A > 180. By the same

reasoning, ∠C + ∠B > 180.

Step 3 Both connections counter the fact that the sum of the measures of the angles of a triangle equals 180.

Thus, the hypotenuse must be the longest side of a right triangle.

Hence, the correct option is C.

Function composition is an operation о used in mathematics that takes two functions, f and g, and creates a function, h = g о f, such that h(x) = g. The function g is applied in this operation to the outcome of applying the function f to x.

Given:

u(x) = x^2 + 3

w(x) = √x+2

We have to find (w о u)(2) and (u о w)(2).

First to find (w о u)(x)

(w о u) = w(u(x))

         = w(x^2 + 3)

(w о u) = √(x^2 + 3) + 2

(w о u)(2) = √(2^2 + 3) + 2

 (w о u)(2) = √7 + 2

Now to find (u о w).

(u о w)(x) = u(w(x))

= u(√x+2)

= (√x+2)^2 + 3

= x + 4√x + 4 + 3

(u о w)(x) = x +  4√x + 7

(u о w)(2)  = 2 + 4√2 + 7

 (u о w)(2)  = 9 + 4√2

Answer:

Lauren has 44 watermelons

Step-by-step explanation:

Let us use W to denote the number of watermelons and O to denote the number of oranges

We have

W:O = 88:14

This can be represented as a fraction:

[tex]\dfrac{W}{O} = \dfrac{88}{14}[/tex]

Divide numerator and denominator of  [tex]\dfrac{88}{14}[/tex]  by 2

[tex]\dfrac{88 \div 2}{14 \div 2} = \dfrac{44}{7}\\\\\\\\\mathrm{So\; \dfrac{W}{O} = \dfrac{44}{7}}\\\\[/tex]

This means for every 7 oranges there are 44 times that number of watermelons

Since we are given that there are 7 oranges she should have 44 watermelons

Another way of looking at this is from the relation

[tex]\dfrac{W}{O} = \dfrac{44}{7}}\\\\[/tex]

Putting in O = 7 we get

[tex]\dfrac{W}{7} = \dfrac{44}{7}\\\\[/tex]

Since the denominators are the same the numerators must be the same i.e. W = 44

Lauren has 44 watermelons

So, the y-coordinate of the solution of the system of equations 3x + 2y = 7 and y - 3x = 11 is 6.

To find the y-coordinate of the solution of a system of equations, we can use one of the methods for solving systems of equations, such as substitution, elimination, or graphing. In this case, we will use substitution method.

The system of equations is:

3x + 2y = 7

y - 3x = 11

We can solve for y in the second equation and get:

y = 3x + 11

Now we can substitute this expression of y into the first equation:

3x + 2(3x + 11) = 7

3x + 6x + 22 = 7

9x + 22 = 7

9x = -15

x = -5/3

Now we can substitute this value of x into the second equation:

y = 3(-5/3) + 11

y = -5 + 11

y = 6

So, the y-coordinate of the solution of the system of equations 3x + 2y = 7 and y - 3x = 11 is 6.

To simplify 9x, you need to use the distributive property.

The distributive property states that when you multiply a number by a group of numbers or variables, you can separate the group into individual components, multiply each component by the number, and then add the products together.

For example, 9x can be simplified as follows:

9x = 9x(1)

Using the distributive property, you can separate the 1 into individual components:

9x = 9x(1) = 9x(1 + 0)

Then, you multiply each component by the number:

9x = 9x(1) = 9x(1 + 0) = 9x(1) + 9x(0)

And finally, you add the products together:

9x = 9x(1) + 9x(0) = 9x + 0

Nelly's gross pay is $451.20 + $84.60 = $535.80.

Gross pay refers to the total amount of money an employee earns before any deductions or taxes are taken out. It is the total amount of money earned by an employee for the hours worked, including any overtime or bonuses.

First, we calculate her regular pay.

She worked 45 hours last week, and her regular hourly rate is $11.28 per hour. Therefore, her regular pay for the week is 40*$11.28 = $451.20. This is the pay she receives for the hours she worked up to 40 hours, which is considered the standard workweek.

Next, we calculate her overtime pay. Nelly worked 45 hours last week, and she is entitled to overtime pay for hours exceeding 40 hours. Therefore, she worked 45-40 = 5 hours of overtime.

Since she is paid time and a half for overtime, her overtime pay is calculated by multiplying her regular hourly rate by 1.5. Therefore, her overtime pay is 5*$11.28*1.5 = $84.60.

Finally, we add her regular pay and her overtime pay to get her gross pay. Her gross pay is the total amount she earns for the week, including both her regular pay and her overtime pay.

The error interval for the area of the shaded region is given as follows:

56.6 < a < 56.8.

The area of the circle is of 78.1 cm², rounded to one decimal place, hence the interval for the area of the circle is of:

78.05 <= area circle < 78.15.

The area of the square is of 21.4 cm², rounded to one decimal place, hence the interval for the area of the circle is of:

21.35 <= area square < 21.45.

The error formula is:

Area circle - Area square.

The minimum error is when the area of the circle is the greatest and the square is the least, hence:

m = 78.15 - 21.35

m = 56.8.

The maximum error is when the area of the circle is the least and the square is the greatest, hence:
