Jerome ate 4/11 of the Pizza how much did that leave for Zachary
Answer:
7/11 of the Pizza was left for Zachary.
Step-by-step explanation:
Zachary had 1 - 4/11
= 11/11 - 4 /11
= 7/11.
Final answer:
Jerome ate 4/11 of the pizza, which means that Zachary has 7/11 of the pizza left to eat after subtracting Jerome's portion from the whole pizza.
Explanation:
If Jerome ate 4/11 of the pizza, we need to determine how much is left. Since the whole pizza represents 1, or 11/11, we subtract what Jerome ate from the whole to find out what remains for Zachary. Therefore, we perform the following subtraction:
1/11 (whole pizza) - 4/11 (portion eaten by Jerome) = 7/11 (portion left for Zachary)
So, Zachary has 7/11 of the pizza left to eat.

Y=2^x-3+2
Y=2^x-2+3
Y=2^x-2-3
[tex]y=2^{\left(x-2\right)}+3[/tex]
Step-by-step explanation:To solve this problem, we need to start with the parent function of the exponential function, which is [tex]f(x)=a^x[/tex], where [tex]a[/tex] is the base. In our problem, [tex]a=2[/tex], so our parent function here is [tex]y=2^x[/tex]. Then, we need to perform some transformations to our parent function. Thus:
1. Vertical shrink:
A vertical shrink is a nonrigid transformation because the graph of the function get a distortion in the shape, so this transformation is as follows:
[tex]g(x)=cf(x)[/tex]
where [tex]c[/tex] in this problem equals 0.25 because:
[tex]y=0.25(2^x) \\ \\ y=\frac{1}{4}(2^x) \\ \\ y=\frac{2^x}{2^2} \\ \\ y=2^{(x-2)}[/tex]
2. Vertical shift:
The graph of the function [tex]y=2^{(x-2)}[/tex] get a vertical shift given by:
[tex]y=2^{(x-2)}+3[/tex]
So the graph is shifted 3 units up. So the result is the graph shown above.

Answer:
x = 6
Step-by-step explanation:
Given the 2 equations
x - y = 4 → (1)
x + y = 8 → (2)
Adding the 2 equations term by term eliminates the y- term
(x + x) + (- y + y) = (4 + 8), that is
2x = 12 ( divide both sides by 2 )
x = 6

The seating space around the basketball court is shown below:
What is the perimeter of the total area?
m
What is the area of the seating space?
m2
Answer:
length=1.05m
perimeter=2.7m
Step-by-step explanation:
18900 in m^2=1.89 m^2
area=length*width
1.89=length*1.8 m
length=1.89÷1.8
length=1.05 m
perimeter=(l+w) 2
perimeter=(1.05+1.8)2
perimeter=2.85×2
perimeter=2.7 m
a. The rectangular backboard’s length in meters is 1.05 meters.
b. The perimeter of the total area in meters is 5.7 meters.
Given the following data:
Area of rectangular backboard = 18,900 [tex]cm^{2}[/tex]Width of rectangular backboard = 1.8 meters.Conversion:
10,000 [tex]cm^{2}[/tex] = 1 [tex]m^2[/tex]
18,900 [tex]cm^{2}[/tex] = X [tex]m^2[/tex]
Cross-multiplying, we have:
[tex]X = \frac{18900}{10000}[/tex]
X = 1.89 [tex]m^2[/tex]
a. To find the backboard’s length in meters:
Mathematically, the area of a rectangle is given by the formula;
[tex]A = LW\\\\1.89 = L(1.8)\\\\L = \frac{1.89}{1.8}[/tex]
Length, L = 1.05 meters.
b. To find the perimeter of the total area in meters:
Mathematically, the perimeter of a rectangle is given by the formula;
[tex]Perimeter = 2(L+W)[/tex]
Substituting the values into the formula, we have;
[tex]Perimeter = 2(1.05+1.8)\\\\Perimeter = 2(2.85)[/tex]
Perimeter = 5.7 meters

The price of product of a company increases by
10% and the turnover increases by 10%. What is
the change in quantity sold?
a. 10%
b. 8%
C. 20%
d. no change
Answer:
d.no change
Step-by-step explanation:
There will be no change in the quantity of products sold.
Option D will be the correct answer.
How do find out the change in quantity sold?Given that the turnover is increased by 10 % when the price increases by 10 %.
Let us consider that the price of the product is x and the quantity sold is n numbers. Then the turnover t will be given as,
[tex]t = x\times n[/tex]
An increase in the price of the product is 10 % results in an increase in turnover by 10%. Hence the increased price is,
[tex]x' = x+\dfrac{10}{100}\times x[/tex]
[tex]x' = 1.1 x[/tex]
Hence new turnover will be,
[tex]t'= x\times n + \dfrac {10}{100} \times x\times n[/tex]
[tex]t'= 1.1\times x\times n[/tex]
The quantity sold can be calculated by dividing the new turnover by the increased price of the product. Thus, the new quantity of the product will be,
[tex]n' = \dfrac {t'}{x'}[/tex]
[tex]n' = \dfrac {1.1\times x\times n}{1.1\times x}[/tex]
[tex]n' =n[/tex]
We can see that the quantity of the product sold remains unchanged.
Hence option D will be the correct answer, there will be no change in the quantity of product sold.

The coordinates of a square are (-7,-7), (6,-7), (6,6) and (?,?)
Answer:
(-7, 6).
Step-by-step explanation:
All sides are equal since it is a square.
The length of the side joining the first 2 points is |-7 - 6| = 13 units and it is horizontal.
The adjacent side is vertical and also has length 13 and moves up from the last line.
So the missing coordinate has a y coordinate of 6 and an x coordinate of -7.

The measures of the legs of a right triangle are 15m and 20m . What is the length of the hypotenuse
Answer:
25 m
Step-by-step explanation:
Use the Pythagorean Theorem.
a^2+b^2=c^2
Or just know you are finding the hypotenuse and use c=sqrt(a^2+b^2)
If you were finding a leg use a=sqrt(c^2-b^2).
So sqrt(15^2+20^2)
=sqrt(225+400)
=sqrt(625)

Find the value of p for which the polynomial 3x^3 -x^2 + px +1 is exactly divisible by x-1, hence factorise the polynomial
ANSWER
[tex]p = - 3[/tex]
The completely factored form is
[tex](x + 1)(x - 1)( 3x - 1)[/tex]
EXPLANATION
The given polynomial expression is
[tex]3 {x}^{3} - {x}^{2} + px + 1[/tex]
Let
[tex]f(x) = 3 {x}^{3} - {x}^{2} + px + 1[/tex]
According to the Remainder Theorem, if f(x) is exactly divisible by x-1, then the remainder is zero.
This implies that:
[tex]f(1) = 0[/tex]
[tex]3 {(1)}^{3} - {(1)}^{2} + p(1)+ 1 = 0[/tex]
[tex]3 - 1 + p + 1 = 0[/tex]
[tex]3 + p = 0[/tex]
[tex]p = - 3[/tex]
When we substitute the value of p back into the function, f(x) we get:
[tex]f(x) = 3 {x}^{3} - {x}^{2} - 3x + 1[/tex]
We now perform long division as shown in the attachment.
We can factor the function to get:
[tex]f(x) =(x - 1)( 3 {x}^{2} + 2x - 1)[/tex]
We now split the middle term of the quadratic term and factor it completely to obtain:
[tex]f(x) =(x - 1)( 3 {x}^{2} + 3x - x - 1)[/tex]
[tex]f(x) =(x - 1)( 3x(x + 1) - 1(x + 1))[/tex]
[tex]f(x) =(x - 1)( 3x - 1)(x + 1) [/tex]
[tex]f(x) =(x + 1)(x - 1)( 3x - 1)[/tex]

How do you simplify i^256? What is i^256 simplified?
A) Divide 256 by 8 and multiply the remainder times i; 0
B) Divide 256 by 4 and use the remainder of 0 as the new power of i.; 1
C) Divide 256 by 6 and use the remainder of 0 as the new power of i.; 0
D) Divide 256 by 6 and use the remainder of 0 as the new power of i.; -1
Answer:
Step-by-step explanation:
You have that [tex]i^2=-1[/tex], so we must have
[tex]i^4=(i^2 )(i^2)=(-1)(-1)=1[/tex].
This says that we must make groups of four [tex]i[/tex]'s for simplify because they becomes 1, and the last group that is not of four [tex]i[/tex]'s is the result.
This is equivalent to divide 256 by 4 and use the remainder of that division, that is 0, as the new power of [tex]i[/tex], and the result is 1 because [tex]i^0 =1.[/tex]. You can see the operation:
[tex]i^{256} = (i^4)^{64}\times i^0 =1[/tex]
use the elimination method to solve the system of equations. 6x+4y=32 -6x+4y=8
Answer:
(2,5)
Step-by-step explanation:
6x+4y=32
-6x+4y=8
We will add the two equations together to eliminate x
6x+4y=32
-6x+4y=8
----------------------
8y = 40
Divide each side by 8
8y/8 = 40/8
y = 5
Multiply the first equation by -1
-6x-4y = -32
-6x+4y=8
------------------
-12x = -24
Divide by -12
-12x/-12 = -24/-12
x = 2
x^2=12x-40 solve this equation using the quadratic formula
Answer:
Step-by-step explanation:
X²=12x-40
X²-12x+40=0
a=1 and b= -12 and c = 40
delta = b² - 4ac
delta = (-12)² - 4(1)(40) = 144 - 160 = - 16 = (4i)² ....i² = -1
x1= (12-4i)/2 =6-2i
x1= (12+4i)/2 =6+2i
Answer:
Step-by-step explanation:
x^2 = 12 x-40
x² - 12x + 40 = 0
a = 1; b = -12; c = 40
4ac - b² = 4*1*40 - (-12)² = 160 - 144 = 16
x = -b ± √4ac-b² i / 2a
= -(-12) ± √ 16 i
2 * 1
= (12 ± 4 i )/ 2
= 2( 6 ± 2i)
2
= 6 ± 2i

Answer:
843.67
Step-by-step explanation:
896 is the original price
A 12% discount will be applied so what is 12% of 896 =.12(896)=107.52
So we started with 896 and we are taking off 107.52=896-107.52=788.48
So the price after the discount is 788.48.
Now to apply the tax which is 7%=.07 so we need to find 7% of 788.48=.07(788.48)=55.19 (This is the tax dollar amount to be added to the price before tax).
So Sara is paying 788.48+55.19=843.67
Answer:
843.67
Step-by-step explanation:
Take the original price and find the discount
896 * 12 %
896 * .12
107.52
The new price is the original price minus the discount
896-107.52
788.48
Now we need to find the tax on the sale price
788.48 * 7%
788.48 *(.07)
55.19
Add the sale price and the tax to find the total price
788.48 +55.19
843.67

Final answer:
The equivalent expression for [tex](4^5/4 \times 4^1/4 \div 4^1/2)^1/2[/tex] is 2, found by applying properties of exponents such as multiplication, division, and power of a power.
Explanation:
The expression given is [tex](4^5/4 \times 4^1/4) \div 4^1/2)^1/2.[/tex] To find the equivalent expression, we use the properties of exponents, which include multiplication, division, and taking a power of a power. When you multiply with the same base, you add the exponents, and when you divide, you subtract the exponents. Also, taking a power of a power means you multiply the exponents.
Following these rules:
Combine the exponents for the terms that multiply: 5/4 + 1/4 = 3/2, hence the expression simplifies to [tex]4^{(3/2)}.[/tex]
Subtract the exponent of the denominator: (3/2) - (1/2) = 1, so now we have [tex]4^1.[/tex]
Finally, apply the outer exponent of [tex]1/2: (4^1)^{(1/2)}[/tex]which means we take the square root of 4, giving us 2 as the final answer.
