Answer:
D. x = +/-sqrt(y - 11)
Step-by-step explanation:
y = x^2 + 11
x^2 + 11 = y
x^2 = y - 11
x = +/-sqrt(y - 11)
What is the slope intercept equation of a line that has a slope of -2 and a y-intercept of (0, 3)
Answer:
y = -2 x +3
Step-by-step explanation:
If the slope must be "-2", then the slope intercept form of the line should look like;
y = m x + b
with the slope "m" = -2
That is:
y = -2 x + b
Now the constant "b" can be found using the info on the value of the y-intercept which is (0, 3), so when x = 0, the value of the y-coordinate must be 3. By imposing this condition into the equation, we can find the value of "b":
3 = -2 (0) + b
3 = b
Then the equation becomes:
y = -2 x +3
Wyatt’s eye-level height is 120 ft above sea level, and Shawn’s eye-level height is 270 ft above sea level. How much farther can Shawn see to the horizon? Use the formula d = StartRoot StartFraction 3 h Over 2 EndFraction EndRoot, h greater-than-or-equal-to 0 with d being the distance they can see in miles and h being their eye-level height in feet.
StartRoot 5 EndRoot mi
3 StartRoot 5 EndRoot mi
15 StartRoot 5 EndRoot mi
45 StartRoot 5 EndRoot mi
Answer:
The answer is 3√5 mi.
The formula is: d = √(3h/2)
Wyatt:
h = 120 ft
d = √(3 * 120/2) = √180 = √(36 * 5) = √36 * √5 = 6√5 mi
Shawn:
h = 270 ft
d = √(3 * 270/2) = √405 = √(81 * 5) = √81 * √5 = 9√5 mi
How much farther can Shawn see to the horizon?
Shawn - Wyatt = 9√5 - 6√5 = 3√5 mi

Answer:
30°
Step-by-step explanation:
Taking a third of 90° is like sharing 90 apples amongst three people.
In effect everyone would have,
[tex] \frac{1}{3} * 90 apples \\ \\ \frac{90}{3}apples \\ \\ 30 apples [/tex]
In the angular world, this problem could be likened to a trisection of 90°, giving you 30°.

The university theater uses a combination of one letter (A – Z) and two digits (0 – 9) to identify their reserved seats. How many reserved seats are possible using a combination of one letter followed by two digits?
1.) 2600
2.) 234
3.) 260
4.) 2106
Answer:
Correct option: 1) 2600
Step-by-step explanation:
The letter has a total of 26 possible values (from 'a' to 'z'), and each digit has a total of 10 possible values (from 0 to 9).
So, to find the number of reserved seats possible, we just need to multiply the number of possible values of each letter and digit.
We have one letter and two digits, so we have:
26 * 10 * 10 = 2600 possible reserved seats
Correct option: 1)
Answer:
1.) 2,600
Step-by-step explanation:
Easy Cooking to a cooking supply company Last year, the company sold 21,000 ovens. This year, they sold 49 fewer ovens than that
How many ovens did they sell this year?
Answer:
20,951
Step-by-step explanation:
If the company sold 21,00 ovens and this year they sold 49 fewer, then that means we are being told to subtract 49 from 21,00 which is the initial value.
21,000-49 = 20,951
therefore, this year they sold 20,951 (twenty-thousand nine hundred fifty one) ovens.
Answer:
20,951 ovens
Step-by-step explanation:
Last year, the company sold 21,000 ovens. This year, they sold 49 fewer ovens that that.
Fewer, means less, or subtractions. Therefore; we must subtract 49 (the difference between this year and last year) from 21,000 (the number of ovens sold this year)
21,000-49
20,951
The company sold 20,951 ovens this year.
If there are 80 toys in a shop, 40% of them are for boys. 50% of the boy's toys and 50% of the girl's toys are made by the shop owner. How many more girl's toys than boy's are made by the owner?
Answer: 8 more girl toys than boy toys
Step-by-step explanation:
First you need to find out how many of the toys are for boys and girls.
———————————————
80 * 40 = 80 * 0.4 = 32
32 toys are for boys
———————————————
80 - 32 = 48
48 toys are for girls
———————————————
Now find 50% of the boy and girl toys.
32 * 50% = 32 * 0.5 = 16
48 * 50% = 48 * 0.5 = 24
———————————————
Now subtract the number of girl toys by the number of boy toys to find out how many more were made for girls than boys.
24 - 16 = 8

The z score is a measure in statistic used to determine the number of standard deviations by which the raw score if from the mean of a normal distribution. If the z score is positive then the raw score is above the mean while if a z score is negative the raw score is below the mean. The z score (z) is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Where x is the raw score, μ is the mean and σ is the standard deviation.
Let us assume that the mean (μ) = 20 and the standard deviation (σ) = 3. To calculate the z score for x = 30 it is given by:
[tex]z=\frac{x-\mu}{\sigma}=\frac{30-20}{3}=3.33[/tex]

The total sales made by a salesperson was $25,000 after 3 months and $68,000
after 23 months. Predict the total sales after 41 months.
$ 106,742
$106,670
$106,800
$106,700
Answer: $106,700
Step-by-step explanation:
y = money amount
x = months
Slope (m) = change in y / change in x = (68000-25000) /(23-3)= 43,000/20= 2,150
Now, we have to write the equation in the form y =mx+b, using one of the points:
25000= 2,150(3) +b
25,000= 6,450+b
25,000-6,450=b
18,550=b
So, the final equation is:
y = 2,150x+18,550
So, when x=41 months
y = 2,150(41)+18,550
y= $106,700

Which function is a quadratic function? y – 3x2 = 3(x2 + 5) + 1 y2 – 7x = 2(x2 + 6) + 7 y – 2x2 = 6(x3 + 5) – 4 y – 5x = 4(x + 5) + 9
Answer:
Option A.
Step-by-step explanation:
The general form of a quadratic function is
[tex]y=ax^2+bx+c[/tex]
It means, power of y should be 1 and highest power of x should be 2.
In option A,
[tex]y-3x^2=3(x^2+5)+1[/tex]
[tex]y-3x^2=3x^2+15+1[/tex]
[tex]y=3x^2+16+3x^2[/tex]
[tex]y=6x^2+16[/tex]
It is a quadratic function.
In option B,
[tex]y^2-7x=2(x^2+6)+7[/tex]
Here, power of y is 2. So, it is not be a quadratic function.
In option C,
[tex]y-2x^2=6(x^3+5)[/tex]
Here, highest power of x is 3. So, it is not be a quadratic function.
In option D,
[tex]y-5x=4(x+5)+9[/tex]
Here, highest power of x is 1. So, it is not be a quadratic function.
Therefore, the correct option is A.

It is A

a) Mr.Wilson bought a mountain bike for Rs 7,600 and sold it at 10% profit. If he had bought it for Rs 8,000, what would be his profit or loss percent?
Answer:
[tex]5\%[/tex] loss.
Step-by-step explanation:
[tex]7600 \times (1+10\%)[/tex]
[tex]7600 \times 1.1=8360[/tex]
[tex]8000 \times (1+10\%)[/tex]
[tex]8000 \times 1.1=8800[/tex]
His loss is Rs 440.
[tex]\frac{440 \times 100}{8800}[/tex]
[tex]=5[/tex]
Answer:
Profit %age = 4.5 %
Step-by-step explanation:
Mr. Wilson bought the bike for = Rs 7,600
Profit %age = 10% of 7,600
Profit = [tex]\frac{10}{100}* 7600[/tex]
Profit = Rs 760
Amount in which the bike is sold = 7600 + 760 = Rs 8360
If Mr. Wilson had bought the bike for Rs. 8000 and sold it in the same amount,
So he would still be
having a profit of Rs. 360
How much Profit %age:
Profit % age = [tex]Profit * 100/CP[/tex]
Profit %age = 360 * 100 / 8000
Profit % age = 36,000 / 8000
Profit %age = 4.5 %
Simplify $\frac{1+\sqrt{2}}{2+\sqrt{3}}$. Your solution can be converted to the form $A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})$, where $A$, $B$, $C$, and $D$ are positive integers. What is $A+B+C+D$?
Answer:
A+B+C+D = 13
Step-by-step explanation:
The given expression is:
[tex]\dfrac{1+\sqrt{2}}{2+\sqrt{3}}[/tex]
We have to simply it and express it in the form of:
[tex]A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})[/tex]
Multiply and divide the given expression with [tex]2-\sqrt 3[/tex]:
[tex]\dfrac{1+\sqrt{2}}{2+\sqrt{3}} \times \dfrac{2-\sqrt 3}{2-\sqrt 3}\\\Rightarrow \dfrac{(1+\sqrt{2}) \times (2-\sqrt 3)}{(2+\sqrt{3})\times (2-\sqrt 3)}\\\Rightarrow \dfrac{2+2\sqrt2-\sqrt3-\sqrt6}{2^2-(\sqrt{3})^2}\\\Rightarrow \dfrac{2+2\sqrt2-\sqrt3-\sqrt6}{4-3}\\\Rightarrow \dfrac{2(1+\sqrt2)-(\sqrt3+\sqrt6)}{1}\\\Rightarrow 2(1+\sqrt2)-(\sqrt3+\sqrt6)[/tex]
It is the simplified form of given expression.
Formula used:
[tex](a+b)(a-b) = a^{2} -b^{2}[/tex]
Comparing the simplified expression with [tex]A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})[/tex]
[tex]2(1+\sqrt2)-(\sqrt3+\sqrt6)=A(1+\sqrt{B})-(\sqrt{C}+\sqrt{D})\\\Rightarrow A =2, B=2, C=3\ and\ D=6[/tex]
So, value of
[tex]A+B+C+D = 2+2+3+6 = 13[/tex]
Determine the value of x in the triangle shown. answers: 48° 42° 228° 132°
Answer:132
Step-by-step explanation:
Answer:
132°
Step-by-step explanation:
first find the interior angle of the triangle.
the interior angle of a triangle is 180°
90°+42°+y°=180°
132°+y°=180°
y°=180°-132°
y°=48°
(y° represents the empty part).
angle on a straight line is equal to 180°
y°+x°=180°
48°+x°=180°
x°=180°-48°
x°=132°
