Answer:

Number of orders on Sunday is actually 139.

Sorry this is late but the tutor did 93 x 2. That's wrong. Must do 93 x 7 and follow my steps below to get a reasonable answer to Sunday which is also close to Saturday.

how do you create a line ?

you mark 2 points, take a ruler and draw a line through both points (and extend the line beyond the points as far as the chart goes).

how do you find points ?

you think about a nice value for x (really, any value on the x-axis of the chart is OK) and then calculate y.

you mark the point at this x, y coordinates.

you know, the x-axis is the horizontal coordinate line, and the y-axis is the vertical coordinate line.

so, I would pick x =0. that gives us y = 0 + 0.5 = 0.5.

and maybe x = 2. that gives us y = 2 + 0.5 = 2.5

so, you have (0, 0.5) and (2, 2.5) as points.

and then simply do as described above.

Step-by-step explanation:

f(x) = x⁴ - 9x³ - 8x² - 9x - 2

f(-3) = (-3)⁴ -9*(-3)³ - 8*(-3)² - 9*(-3) - 2

       = 81 - 9*(-27) - 8*9  + 27 -2

       = 81 + 243 - 72 + 27 - 2

      = 277

Answer:

[tex]F(-3)=142[/tex]

Substitute x=-3 into

[tex]F(x)=x\times4-9x\times3-8x\times2-9x-2[/tex]

Substitute

[tex]F(-3)=-3\times4-9\times(-3)\times3-8\times(-3)\times2-9\times(-3)-2[/tex]

Determine the sign

[tex]F\left(-3\right)=-3\times4+9\times3\times3+8\times3\times2+9\times3-2[/tex]

Calculate the product or quotient

[tex]F(-3)=-12+9\times3\times3+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+27\times3+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+8\times3\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+24\times2+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+48+9\times3-2[/tex]

[tex]F\left(-3\right)=-12+81+48+27-2[/tex]

Calculate the sum or difference

[tex]F(-3)=69+48+27-2[/tex]

[tex]F(-3)=117+27-2\\F(-3)=144-2\\F(-3)=142[/tex]

To solve this problem, you need to divide the total number of students going on the field trips with the number of students in each group.

44/7

= 6 R 2

Since, I assume there can only be groups of 7, the answer is 6.

The value of m in the proportion is 5/78.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

To solve for m in the proportion:

1/2/3/5 = 13m

We can simplify the left-hand side of the equation by multiplying the first fraction by the reciprocal of the second fraction, and multiplying the third fraction by the reciprocal of the fourth fraction. This gives:

(1/2) ÷ (3/5) = 13m

(1/2) × (5/3) = 13m (using the rule a/b ÷ c/d = a/b × d/c)

5/6 = 13m

To isolate m, we can divide both sides of the equation by 13:

5/6 ÷ 13 = m

m = 5/78

Therefore, the value of m in the proportion is 5/78.

Rounded to the nearest cent, the cost of 1700 bricks would be $504.21.

To determine the cost of 1700 bricks, we need to calculate the total weight of the bricks and then multiply it by the cost per ounce.

Calculate the volume of one brick:

- Length = [tex]8\frac{1}{2}[/tex] inches

- Width = [tex]3\frac{1}{4}[/tex] inches

- Height = [tex]3\frac{1}{2}[/tex] inches

Volume = Length x Width x Height

Then Weight per cubic inch = 0.04 ounces

Weight = Volume x Weight per cubic inch

To Calculate the total weight of 1700 bricks:

Total weight = Weight per brick x Number of bricks

Cost per ounce = $0.08

Cost = Total weight x Cost per ounce

Volume = 8.5 inches x 3.25 inches x 3.5 inches

Weight per cubic inch = 0.04 ounces

Weight = Volume x Weight per cubic inch

The Total weight of 1700 bricks:

Total weight = Weight x 1700

Cost per ounce = $0.08

Cost = Total weight x Cost per ounce

1. Volume of one brick:

Volume = 8.5 inches x 3.25 inches x 3.5 inches = 92.6875 cubic inches

2. Weight of one brick:

Weight per cubic inch = 0.04 ounces

Weight = 92.6875 cubic inches x 0.04 ounces = 3.7075 ounces

3. Total weight of 1700 bricks:

Total weight = 3.7075 ounces x 1700 = 6302.575 ounces

4. Cost of the bricks:

Cost per ounce = $0.08

Cost = 6302.575 ounces x $0.08 = $504.21

Rounded to the nearest cent, the cost of 1700 bricks is $504.21.

Encourage extensive and intensive reading;

Invite natural discussions that lead to student inquiry and critical

Thinking;

Support diverse responses to text;

Foster interaction, cooperation and collaboration;

Provide choice and encourage responsibility;

Expose students to literature from multiple perspectives; and

Nurture reflection and self-evaluation.

Answer:

x^3 - 21x^2 + 144x - 324

Step-by-step explanation:

f(x) = x^2 - 15x + 54

g(x) = x - 6

To find f(x) x g(x), you just substitute the values of f(x) and multiply it with g(x).

(x^2-15x+54)(x-6) = x^3 - 15x^2 + 54x - 6x^2 + 90x - 324

                            = x^3 - 21x^2 + 144x - 324

The value of r is 4 feet, the correct option is A.

The area of a circle is the region occupied by the circle in a two-dimensional plane.

Given

The area of circle Z is 64 ft2.

According to the following formula, we must find the radius of the circle:

[tex]\rm r =\sqrt{\dfrac{Area}{\pi }}[/tex]

Substitute all the values in the formula

[tex]\rm r =\sqrt{\dfrac{Area}{\pi }}\\\\\rm r =\sqrt{\dfrac{64}{3.14}}\\\\\rm r =\sqrt{20.38}\\\\r=4.5[/tex]

Hence, the value of r is 4 feet.

Step-by-step explanation:-

If the altitude to the hypotenuse of a right-angled triangle bisects the hypotenuse, then we can know that the triangle is Isosceles right triangle. (AB=AC)

Make AB=AC=2, so,

BC=[tex] \sqrt{ {2}^{2} + {2}^{2} } [/tex]= [tex] \sqrt{4 + 4} [/tex]= [tex] \sqrt{8} [/tex]

Prime factorizing, we get,

BC = [tex] \sqrt{2 \times 2 \times 2} [/tex]

Take two 2's outside by taking common because of "square" root,

⇢BC = [tex]2 \sqrt{2} [/tex]

BD = DC = [tex] \sqrt{2} [/tex],

AD = [tex] \sqrt{AB^{2} - BD^{2} } [/tex]= [tex] \sqrt{4 - 2} [/tex]= [tex] \sqrt{2} [/tex]

So, AD=BD=CD= [tex] \frac{1}{2}[/tex]BC

For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

In order to calculate the value of the P(z≤0.42), we need to check the value of 0.42 in the z-table, As the Z-table is already given and in the table, the value of z is 0.6628, therefore,

[tex]P(z\leq 0.42)\\\\=0.6628 \approx 66\\\\= 66\%[/tex]

Hence, For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.
