A grid shows the positions of a subway stop and your house. The subway stop is located at (7,3) and your house is located at (4-5). What is
the distance, to the nearest unit, between your house and the subway stop?
Answer:
9 units
Step-by-step explanation:
In a coordinate plane with point P( x , y) and Q(a,b ).
distance between these are points is given by equation
distance between PQ = [tex]\sqrt{(x-a)^2 + (y-b)^2}[/tex].
Coordinate of subway stop = (7,3)
Coordinate of house = (4-5)
Therefore using the above the formula to calculate distance between
house and the subway stop is given by
distance = [tex]\sqrt{(7-4)^2 + (3-(-5)^2}\\\\=>\sqrt{(3)^2 + (3+5)^2}\\\\=>\sqrt{9 + (8)^2}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{73}\\\\=>8.544[/tex]
Therefore, distance between house and the subway stop is 8.544 units.
But it is given that distance should be to the nearest unit.
any decimal value greater than or equal to .5 is equivalent to 1 in nearest unit.
Thus, 8.544 units is equivalent to 9 units (in nearest unit)
A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?
Answer:
Step-by-step explanation:
Please help with this
Answer:
C
Step-by-step explanation:
A quadratic function can be defined as a function where the highest degree or exponent is 2. Since option B has a zero in front of the x squared, it is not a quadratic function because 0 times anything is zero. Therefore, the only other option with an exponent of 2 is C.

Which expression represents finding the volume of the entire solid? Be careful
Answer:
Option 6
Step-by-step explanation:
To find the volume of a cone you use the formula 1/3*pi*r^2*h which would be pi*9^2*7. Then the volume of a cylinder is pi*9^2*50, so option 6 is right I believe.

Ben decided to invest his savings into a friends local business if he invests 1,750 at an annual interest rate of 6.4% how much interest will he earn in 4 years
Answer:
He will earn an interest of $448 in 4 years
Step-by-step explanation:
In this question, we are interested in calculating the interest earned on an investment for a period of 4 years.
To calculate this interest, we shall be using the formula for simple interest but with slight difference in terms definition
Mathematically;
I = PRT/100
Where ;
P is the amount invested which is $1,750 according to the question
R is the interest rate which is 6.4%
T is the time which is equal to 4 years
Plugging these figures, we have
I = (1,750 * 6.4 * 4)/100 = 44,800/100 = $448

A company's stock began the day at $25.28 per share. That price drops by $1.16 each hour. A. What is the price per share after 5 hours? B. What will it be after 23 hours if this rate continues? C. Explain what the signs of the answers mean in this context.
Answer: A.) $19.48
B.) -$1.40
C.) The sign in B, the negative, means that if the price of the share were to continue dropping, then it will become negative.
Step-by-step explanation:
A. The price per share after 5 hours will be $19.48.
B. It will be $19.48 per share after 23 hours if this rate continues.
C. The sign indicates the company is at a loss.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that, A company's stock began the day at $25.28 per share. That price drops by $1.16 each hour.
1 hour = $1.16
5 hour =5 × $1.16
5 hours =$ 5.8 per share
The price drops per share after 5 hours are,
=$25.28-$ 5.8
=$19.48
B)
If the price drops by $1.16 each hour. The price after 23 hours will be,
1 hour = $1.16
23 hour =23 × $1.16
23 hours =$ 26.68 per share
=$25.28 -$ 26.68
=-$1.40 per share
Thus, the price per share after 5 hours will be $19.48, It will be $19.48 per share after 23 hours if this rate continues and the sign indicates the company is at a loss.

Find the volume of a pyramid with a square base, where the area of the base is
8.7 m and the height of the pyramid is 10 m. Round your answer to the nearest
tenth of a cubic meter.
Answer: 29.0
Step-by-step explanation:
The volume of a pyramid is equal to l*w*h/ 3 and we know that the length times the width is the same as the base.
so we will multiply 8.7 * 10= 87 /3= 29
Volume = 87 m³
You need to multiply the area and the height to find the volume. If you have the length, width, and height, then you need to multiply and 3 and divide it by 3. Hope I helped :)
these 15 colored pencils make up 20% of jordon's colored pencil collection.how many colored pencils does jordon have in his collections
Answer:
75 coloured pencils
Step-by-step explanation:
Let's say Jordon has x total pencils.
We know that 20% of these x pencils is 15, so we have:
20% * x = 15
Remember that % is just "out of 100", so 20% = 20/100 = 0.20. Then:
0.20x = 15
x = 15 / 0.20 = 75
Jordon has 75 coloured pencils.
Answer:
75 pencils
Step-by-step explanation:
Let the total no. of pencils be T
20% of T = 15
20/100 × T = 15
T = 15 × 100/20
T = 15 × 5
T = 75

A rectangular playground is 10m longer than it is wide.The area of the playground is 1400m² Calculate the width and length of the playground. solve using quadratic formula please?
Answer:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Step-by-step explanation:
For this case we know that we have a rectangular playground and the area can be founded with this formula:
[tex] A = xy[/tex]
Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:
[tex] y = 10 +x [/tex]
And replacing this formula into the area we got:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Answer:
Step-by-step explanation:
Given Data:
Area = 1400m²
L = 4+w
W= w
Area = L * W
1400 = ( 4+W) W ²
1400 = 4w + w ²
w ² + 4w - 1400 = 0
- b ± √ b ² - 4ac / 2a
Where;
a = 1
b = 4
c = -1400
- 4 ± √4² - 4(1)(-1400) / 2(1)
= - 4 ± 74.94 /2
= - 4 + 74.94 / 2 or - 4 - 74.94 / 2
= 35.47 or - 39.47

Suppose the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales. Find the z-score associated with the upper boundary of of this price range.
Answer:
The z-score associated with the upper boundary of of this price range is -0.25.
Step-by-step explanation:
It is provided that the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales.
If X represents the price range of drink sales, then
P (X < x) = 0.40
Consider that X follows a Normal distribution.
To compute the probability of a normally distributed random variable we need to first convert the raw score to the z-scores.
The formula to z-score is:
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Then,
P (X < x) = 0.40
⇒ P (Z < z) = 0.40
The value of z for this probability is:
z = -0.25
*Use a z-table.
Thus, the z-score associated with the upper boundary of of this price range is -0.25.
Answer:
-0.25

Ernesto wants to buy a snack from the vending machine. The vending machine has 5 different kinds of chips, 8 different candy bars, and 2 different kinds of cookies. If he chooses one at random, what is the probability that it is a cookie?
Answer:
The probability that it is a cookie is [tex]\frac{2}{15}[/tex]
Step-by-step explanation:
To find the probability that it is a cookie if he chooses one at random;
probability = required outcome / all possible outcome
The all possible outcome will be gotten by adding up all the snacks. that is;
required outcome = 5 + 8 + 2 = 15
The required outcome is the snack he chooses, that is; required outcome = 2
Probability (of choosing a cookie) =required outcome / all possible outcome
=[tex]\frac{2}{15}[/tex]
Therefore, the probability that it is a cookie is [tex]\frac{2}{15}[/tex]
