Answer:
3x³ + 17x² + 33x + 27
Explanation:
(x + 3)(3x² + 8x + 9)
= (x + 3)(3x² + 8x + 9)
= (x)(3x²) + (x)(8x) + (x)(9) + (3)(3x²) + (3)(8x) + (3)(9)
= 3x³ + 8x² + 9x + 9x² + 24x + 27
= 3x³ + 17x² + 33x + 27
Expand 4(-2x - 3)
Factorise 5n + 15

A sporting equipment company wants to sell a new bicycle helmet. They have developed a function, shown below, where total profit, p, can be determined based on sale price, s.
What will be the total profit if the sale price of the helmet is $60?
Answer:
[tex] p(s) = -24s^2 +2200 s -18000[/tex]
If we use the valie of s =60 we have
[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]
And after solve we got:
[tex] p(60)= -86400 +132000 -18000 =27600[/tex]
So then the best option for this case would be:
$27,600
Step-by-step explanation:
Using the following info in order to complete the problem:
p(s)=-24s^(2)+2200s-18000
$112,560
$27,600
$111,120
$236,400
$14,240
We have the following function given:
[tex] p(s) = -24s^2 +2200 s -18000[/tex]
If we use the valie of s =60 we have
[tex] p(60) = -24 (60)^2 +2200*60 -18000[/tex]
And after solve we got:
[tex] p(60)= -86400 +132000 -18000 =27600[/tex]
So then the best option for this case would be:
$27,600

What is the measure of Arc CB. How did you determine this?
Answer:
As shown in picture,
Angle CDF = Angle BDE = 54 deg (pair of opposite angles)
Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).
=> Arc CB = Angle CDB = 126 deg (property of angle on circle)
Hope this helps!

Dylan has a square piece of metal that measures 17 inches on each side. He cuts the metal along the diagonal, forming two right triangles. What is the length of the hypotenuse of each right triangle to the nearest tenth of an inch?
Answer:
24 Inch
Step-by-step explanation:
When the square piece of metal is cut along the diagonal, it forms two right triangles where each of the right triangle has legs of 17 inches.
To determine the length of the hypotenuse, we use the Pythagorean Theorem.
[tex]\text{Pythagoras Theorem}: Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=17^2+17^2\\Hypotenuse^2=289+289\\Hypotenuse^2=578\\Hypotenuse=\sqrt{578} \\=24.04\\\approx 24$ inch ( to the nearest tenth of an inch)[/tex]
Answer:
24 square inches

Good luck on your assignment
Answer:
$374.63
Step-by-step explanation:
Find the interest paid by the bank per year by working out 6.75% of 1850 (1850x0.0675)
Then multiply this by 3 as it is three years, to get 374.625, then round it to 2 decimal places.
find the square root of each of the following decimal numbers correct to two places of decimal : I. 175.01 II. 423.74 III. 5893.27 iv.7136.8
Answer:
i. 13.23
ii. 20.58

Nathan took his car in for service and repair. He had a coupon for 15% off. $261.36 $381.25 $77.52 Which amount is closest to Nathan's total costs after the 15% discount and 7% sales tax?
Answer:
Total amount to be paid = $655
Step-by-step explanation:
Given,
Total price before coupon is = 261.36 +381.25+77.52
= $720.13
Discount = 15%
Amount of discount = 15% of total amount
Amount of discount = [tex]\frac{15}{100} \times 720.13[/tex]
= $108.02
Remaining amount = Total amount - discount amount
Remaining amount = $720.13 - $108.02
= $612.11
Sales tax = 6%
Amount of sales tax = 6% of remaining amount
[tex]=\frac{6}{100} \times 612.11\\\\=42.85[/tex]
Amount to be paid = Remaining amount + sales tax
= 612.11 + 42.85
= 654.96
Rounding off to nearest whole number;
Total amount to be paid = $655
Aiyanah made 12 withdrawals of $175.25 each from her bank account. Then she made 17 deposits of $235.66 to her same account that same day. What was the overall change in her account that day?
Answer:
The overall change is $1903.22
Step-by-step explanation:
Let us approach this problem step wise
1.Firstly let us calculate all 12 withdrawal of $175.25
12*$175.25= $2103
2. Let us calculate all the deposits made 17* $235.66 = $4006.22
With these figures we can calculate the overall changes as
= $4006.22-$2103= $1903.22

Based on the description of the scenario, which of the variables is the dependent variable?
Answer:
We need the scenario.
Step-by-step explanation:
Generally the independent variable is the thing you are changing and the dependent variable is being changed based on the independent variable.
Ex:
y= x+1
x is the independent variable because you can put in whatever value you want in and y is the dependent variable because its value depends on what you choose for x if that makes sense. I would need you scenario to be able to tell you exactly what it is.
Answer:
For the first one test score
For the second one it's y-axis

Step-by-step explanation:
The ratio of yes votes to no votes was 5 to 7. If there were 10,092 total votes, how many yes votes were there?
Answer:
4,205
Step-by-step explanation:
5 + 7 = 12
10,092 ÷ 12 = 841
multiplier for the ratio is therefore 841.
5:7 is yes:no
since you want the number of yes votes, u take the 5 and multiply it by the multiplier found before.
5 × 841 = 4,205 yes votes.
Please help me in this small question.
Answer:
y = 80
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , thus
sum = 180° × 3 = 540°
Sum the internal angles and equate to 540
110 + y + 2y + y + 110 = 540 , that is
4y + 220 = 540 ( subtract 220 from both sides )
4y = 320 ( divide both sides by 4 )
y = 80

What is the measure of angle b ?!
Answer:
the answer is 47
Step-by-step explanation:
first you would add the sum of angle A to the sum of angle D. next you would subtract 180 from 133 to get 47. then you can check your answer by adding 34 and 47 which is 81 and then subtract that from 180 to get the measure of angle D.
34+99=133: 180-133=47
34+47=81: 180-81=99
Hope this helps.

Which series of transformations results in a figure that is SIMILAR to the original figure. Select all that apply.
Translation, Reflection, Rotation
Translation, Dilation, Reflection
Dilation, Reflection, Rotation
Rotation, Rotation, Translation
Rotation, Translation, Reflectio
Answer:
Translation, Reflection, Rotation
Step-by-step explanation:
In mathematics, objects undergo series of transformations. Transformation can be defined as the movement of an object from one particular position to another position
The transformations that an object undergoes are such that the resulting figure created is SIMILAR TO OR THE SAME AS the original figure is referred to as ISOMETRIC TRANSFORMATIONS.
They are:
a) Translation: The movement that occurs in translation of objects is the sliding movement. During translation, an objects is moved from one point to another point without rotating or reflecting the object. This is also known as sliding.
b) Reflection: During reflection, an object is transformed turning it over the line of reflection to another side or position.
c) Rotation: Rotation is the transformation of an object by rotating the object about a fixed point.
In the U.S., approximately 8.3% of the population has diabetes. Maryland's rate of diabetes for its residents is 12% higher than the national average. What is the rate of diabetes in the state of Maryland? *
Answer:
9.30%
Step-by-step explanation:
Given;
The average rate in the national average N = 8.3%
The average rate in Maryland R = 12% higher than national
R = N + 12% of N
R = N + 0.12N
R = 1.12N
R = 1.12 × 8.3%
R = 9.296%
R = 9.30%
Rate of diabetes in Maryland = 9.30%

a rectangle is reduced by a scale factor of 1/4 which choices show the ratio of the area hurry because i need this for a test
Aleecha107Junior Moderator
Answer:
The area would be 1 : 16 ratio, of the smaller rectangle to the larger one.
Step-by-step explanation:
I used a rectangle with the side length of 1 to model this for me. You can choose any number, but 1 is easy to multiply.
If the original rectangle had a side length of 1 and 1, the area would be 1.
If you reduce the size to 1/4th of the size, the area would be 0.0625, or 1/16th of the original.
I hope this helped!
