A store in Madrid, Spain, specializes in selling toys for children ages 1 to 10. In
August 2020, one euro was equal to 1.18 United States dollars ($). The graph
below represents the profit, P, in dollars, that is generated by selling a new toy
with a price of x dollars.
Answer:
b and c
Step-by-step explanation:
In this exercise we have to use the knowledge of parabolas to describe the value, in this way we have to:
Letter C
In this exercise we are dealing with a parabola and we can solve it just by looking at the values and the graph, so:
When we have a parabola, its peak relates to the highest profit value on the Y axis, so we find the profit of 150 dollars when the X axis represents the value of the toy in 6 dollars.See more about parabola at brainly.com/question/8495504

Enter the following phrase as an algebraic expression. Let x represent the unknown number.
Three times a number, increased by 6
3x(6)
If you want me to solve it reply
if f(x)=-3x-2 find f(3)
Answer:
-11
Step-by-step explanation:
Answer:
-11
Step-by-step explanation:
f(3) means that you plug in 3 for x in the entire equation of f(x)
This means when f(x) = -3x - 2
f(3) = -(3)(3) - 2
= -9 -2
= -11

Which expression shows the area of the shaded part of the grid? A hundred grid model showing a 7 4 array shaded blue. A. 0.04 × 0.07 B. 0.5 × 0.7 C. 0.4 × 0.7 D. 0.3 × 0.6
Answer:
[tex]C.\ Area = 0.4 * 0.7[/tex]
Step-by-step explanation:
See attachment for grid
From the attachment:
There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.
This implies that, the measurement of each cell is:
[tex]Each\ Cell = \frac{10}{10 * 10}[/tex]
[tex]Each\ Cell = \frac{1}{10}[/tex]
[tex]Each\ Cell = 0.10[/tex]
The horizontal axis has 7 selected cells.
This measures
[tex]Horizontal = 7 * 0.10 = 0.70[/tex]
The vertical axis has 4 selected cells.
This measures
[tex]Vertical = 4 * 0.10 = 0.40[/tex]
So, the selected area is:
[tex]Area = Vertical * Horizontal[/tex]
[tex]Area = 0.40 * 0.70[/tex]
or
[tex]Area = 0.4 * 0.7[/tex]
A 2003 New York Times CBS news poll sampled 523 adults who were planning a vacation during the next 6 months and found that 141 were expecting to travel by airplane. A similar survey question in May 1993 New York Times CBS news poll found that of 477 adults who were planning to take a vacation in the next 6 months, 81 were planning to travel by airplane. State the hypotheses that can be used to determine whether a significant change occurred in the population proportion planning to travel by airplane over 10 years.
Answer:
The solution can be defined as follows:
Step-by-step explanation:
[tex]H_0 : p_1 = p_2\\\\H_a : p_1 \neq p_2\\[/tex]
Testing the statistics values:
[tex]p_1 = \frac{141}{523} = 0.2696 \\\\ n_1 = 523\\\\p_2 = \frac{81}{477} = 0.1698\\\\ n_2 = 477[/tex]
[tex]p = \frac{(p_1 \times n_1 + p_2 \times n_2)}{(n_1 + n_2)}[/tex]
[tex]= \frac{(0.2696 \times 523 + 0.1698 \times 477)}{( 523 + 477)}\\\\= \frac{(141.0008 + 80.9946)}{(1000)}\\\\= \frac{(221.99)}{(1000)}\\\\= \frac{(222.0)}{(1000)}\\\\= 0.2220[/tex]
[tex]SE = \sqrt{ p \times ( 1 - p ) \times [ (\frac{1}{n_1}) + (\frac{1}{n_2}) ] }[/tex]
[tex]= \sqrt{( 0.222 \times (1-0.222) \times((\frac{1}{523}) + (\frac{1}{477})))}\\\\= 0.0263[/tex]
[tex]z = \frac{(p_1 - p_2)}{SE}[/tex]
[tex]= \frac{( 0.2696 - 0.1698)}{0.0263}\\\\= 3.7947[/tex]
p = 0.0001
It reject all the null hypothesis values
Please help!!! Geometry
Answer:
x=26
Step-by-step explanation:
We can use the Pythagorean theorem for this answer.
Pythagorean Theorem: a^2 +b^2 = c^2
We can see that both triangles are right triangles. We should first find the hypotonus of the bottom triangle.
So, we plug in the values.
6^2 +8^2 = c^2
36 +64 = c^2
c^2= 100
c= square root of 100
c=10
The hypotonus for the bottom triangle is equivalent to the base of the top triangle. Therefore, we can use the Pythagorean Theorem again.
10^2 +24^2= c^2
100+576+c^2
c^2 = 676
c= square root of 676
c= 26
The answer to the problem is 26.

What is the volume of this rectangular prism?
Answer:
[tex]V =\frac{12}{5}\ cm^3[/tex]
Step-by-step explanation:
The Volume of Rectangular Prism
Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:
V = WLH
The figure shows the dimensions:
L=3 cm
[tex]W=\frac{4}{3}\ cm[/tex]
[tex]H=\frac{3}{5}\ cm[/tex]
Thus, the volume is:
[tex]V =3*\frac{4}{3}*\frac{3}{5}\ cm^3[/tex]
[tex]V =\frac{36}{15}\ cm^3[/tex]
Simplifying:
[tex]\boxed{V =\frac{12}{5}\ cm^3}[/tex]
Evaluate the difference quotient for the given function. Simplify your answer. f(x) = 1 x , f(x) − f(a) x − a
Answer:
[tex]\frac{f(x) - f(a)}{x - a}=\frac{-1}{xa}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{1}{x}[/tex]
Required
Evaluate [tex]\frac{f(x) - f(a)}{x - a}[/tex]
We have:
[tex]f(x) = \frac{1}{x}[/tex]
Next, we calculate f(a)
Substitute a for x in [tex]f(x) = \frac{1}{x}[/tex]
[tex]f(a) = \frac{1}{a}[/tex]
Substitute values for f(x) and f(a) in [tex]\frac{f(x) - f(a)}{x - a}[/tex]
[tex]\frac{\frac{1}{x} - \frac{1}{a}}{x - a}[/tex]
Take LCM of the numerator
[tex]\frac{\frac{a - x}{xa} }{x - a}[/tex]
Split:
[tex]\frac{a - x}{xa} /{x - a}[/tex]
Convert / to *
[tex]\frac{a - x}{xa} *\frac{1}{x - a}[/tex]
Express a - x as -(x-a)
[tex]\frac{-(x - a)}{xa} *\frac{1}{x - a}[/tex]
Divide numerator and denominator by x - a
[tex]\frac{-1}{xa} *\frac{1}{1}[/tex]
[tex]\frac{-1}{xa}[/tex]
Hence:
[tex]\frac{f(x) - f(a)}{x - a}=\frac{-1}{xa}[/tex]

Which equation matches the hanger?
O X+3=6
0 3x = 6
0 6 = 3x +1
2x = 6
Answer:
B. 3x = 6
Step-by-step explanation:
The left side of a hanger is on the left side of the equation, and the right side of a hanger is on the right side of the equation.
There are 3 x's on the left side, so the left side is 3x
The right side shows 6 unit boxes, so the right side is (1 * 6), or 6.
As a result, the equation is 3x = 6, which is B.

Factorise 2xsquared X 7x +3
Answer:
(-2x - 1) • (x + 3)
Step-by-step explanation:
3.2 Factoring 2x2 + 7x + 3
The first term is, 2x2 its coefficient is 2 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is 7 .
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 6
2x2 + 1x + 6x + 3
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x+1)
Add up the last 2 terms, pulling out common factors :
3 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x+1)
Which is the desired factorization

Find the total cost for a $64 gift that has been marked up 30%. *
Glover Inc. manufactures Product B, incurring variable costs of $15.00 per unit and fixed costs of $70,000. Glover desires a profit equal to a 12% rate of return on assets. Assets of $785,000 are devoted to producing Product B, and 100,000 units are expected to be produced and sold.
Answer:
Step-by-step explanation:
The questions are:
a. Compute the markup percentage using the total cost concept.
b. Compute the selling price of Product B.
a. The mark up percentage will be calculated as:
= Desired Profit / Total Cost
= ($785000 × 12%) / [($15 × 100,000) + $70,000]
= ($785,000 × 0.12) / [($15 × 100,000) + $70,000]
= $94,200 / $1,570,000
= 0.06
= 6%
b. Selling price of Product B will be calculated as:
= Cost amount per unit + Markup
= $15.70 + ($15.70 × 6%)
= $15.70 + $0.94
= $16.64

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
Answer: 48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.

2. Factor [tex](2x^{2} -3x-2)[/tex].
X-Method:
1. Draw an X
2. Multiply ac (2(-2)=-4) then put it in the top part of the X
3. Then put b, -3, in the bottom part of the X
4. On the two sides of the X find out what added together equals b, -3,
and multiplied equals ac, -4.
5. -4(1)=-4 & -4+1=-3
6. If the quadratic has a coefficient then you must divide the two sides
of the X by that coefficient, 2.
7. -4/2=-2 & 1/2 can't be evenly divided into, so in this case the
coefficient remains.
8. When you write this out it will be (2x+1)(x-2)
3. Put it together to get your answer.
