Answer: 590.98217751
Step-by-step explanation:
32,400(1+0.05)^8
32,400(1.05)^8
590.98217751
Answer:
47,870
Step-by-step explanation:
Plug in 32,400 page views for the initial amount, 0.05 for the rate of increase, and 8 months for the time elapsed.
y
= a(1+r)t
y
= 32,400(1+0.05)8 Plug in values
y
= 32,400(1.05)8 Add
y
= 32,400(1.47745…) Simplify
y
= 47,869.55637… Multiply
Round to the nearest whole number.
47,869.55637… → 47,870
To the nearest whole number, Isaac can expect 47,870 page views.
Find the distance between the points (3, -5) and (6, -5).
Answer:
0 (i think??)
Step-by-step explanation:
use the equation to find the slope:
y2 - y1/ x2 - x1 or y1 - y2/x1 - x2
sooo
(3, -5) (6, -5)
-5 - (-5) / 3 - 6
-5 + 5/ -3
0
Answer:
3
Step-by-step explanation:
The y-values of both points is -5. This means that the line between the points is a horiztonal line. Therefore the distance between the points is simply the difference between the x-values: 6 - 3 = 3
Given f (x) = 17 minus x squared, what is the average rate of change in f(x) over the interval [1, 5]? –6 Negative one-half One-fourth 1.
The average rate of change in f(x) over (1,5) is -6.
Given function is:
[tex]f(x) =17-x^{2}[/tex]
[tex]f(5) = -8\\\\f(1) = 16[/tex]
What is the average rate of change in a function over an interval?The average rate of change is a measure of how much the function changed per unit, on average, over that interval.
We know that
The average rate of change in f(x) over (a,b) is given by:
The average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
So, The average rate of change in f(x) over (1,5) = [tex]\frac{f(5)-f(1)}{5-1}[/tex]
The average rate of change in f(x) over (1,5) = [tex]\frac{-8-16}{5-1}[/tex]
The average rate of change in f(x) over (1,5) = -6.
Therefore, the average rate of change in f(x) over (1,5) is -6.

Step-by-step explanation:
lison had 310 rocks in her rock collection. After three months, her collection increases by 40%. How many rocks does Alison have now?
Answer:
434
Step-by-step explanation:
310 * 1.4 = 434
or if you want to break it up more:
10% of 310 = 31 (to get 10% divide by 10)
to get from 10% to 40% multiply your answer by 4
31 * 4 = 124
so 40% = 124
this means over the three months Allison's rock collection increased by 124.
to get the total amount of rocks Allison has now add the increase to the original value
310 + 124 = 434

Find N' after N(2, 3) was reflected over the line y = x + 2.
Answer:
Step-by-step explanation:
Did u find the answer?
The reflected over the line y=x+2 is A''(-3,-2). Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the other side of the line.
What is meant by reflected over the line?Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the other side of the line. This transformation is known as a reflection over line.
A transformational process turns a figure into a reflection. Figures can be reflected in a point, a line, or a plane. When reflecting a figure in a line or a point, the image and preimage coincide. A reflection converts each point of a figure from a point to an image across a fixed line.
From the additional image, you can see that the coordinates of image point A' are after reflection point A about the line y=-x (-3,2).
Next, the coordinates of reflection point A' about the x-axis are (-3,-2).
The complete question is : Find the image of A (-2,3) reflected in the line y= -x and then in the x axis

Applying the concept of supplementary angles, their measures are of 60º and 120º.
What are supplementary angles?Two angles are called supplementary if the sum of their measures is of 180º.
In this problem, we have that the measurement of one angle is half the measurement of the other, and they are supplementary, hence:
[tex]x + \frac{x}{2} = 180[/tex]
[tex]\frac{3x}{2} = 180[/tex]
3x = 360
x = 120

They need to park the Mystery Machine. They could either park in the lot that charges $5 and then $2 an hour, or they could park using the meter on the street that charges $3.75 per hour.
Write an equation that describes when the cost is the same at both locations (the parking lot and on the street).
Please, I just need an equation
Answer: 5 + 2x = 3.75x
Step-by-step explanation:
From the question, they could either park in the lot that charges $5 and then $2 an hour, or they could park using the meter on the street that charges $3.75 per hour.
The equation that describes when the cost is the same at both locations goes thus:
Let the number of hours used be x
The equation can then be written as:
$5 + $2x = $3.75x
5 + 2x = 3.75x

Answer:
*I just learned that in probability if a question has 'and' it means you multiply and if it has 'or' it means you add*
1a) 1/6
There are two numbers greater than four (5 and 6). There are 6 possible numbers you can get, so the fraction would be 2/6, or simplified would be 1/3. There are two options you can get when flipping a coin, so the chance of getting a head is 1/2. This is an 'and' problem so multiply 1/3•1/2 and you get 1/6.
1b) 1/4
There are 3 even numbers (2, 4, and 6), so the probability would be 3/6 or simplified to 1/2. The chance of landing on a tail is also 1/2, as there are two possible options. This is an 'and' problem so multiply 1/2•1/2 and you get 1/4.
2) 1/8
Write out your possible results: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.
3a) 1/8
There are 4 shirt options to choose from. The chance of picking blue is 1/4. There are 2 pant options. The chance of picking black is 1/2. This is an 'and' problem, so multiply 1/4•1/2 and you get 1/8.
3b) 1/4
There are 4 shirt options to choose from. This is an 'or' problem because he can choose an orange shirt OR a red shirt. The probability of picking an orange shirt is 1/4 and the probability of picking a red shirt is 1/4. 'Or' means you use addition so add 1/4+1/4 and you get 2/4 or simplified is 1/2. There are 2 pant options to choose from, so the probability of choosing brown pants is 1/2. Now, this is an 'and' problem, so multiply 1/2•1/2 and you get 1/4.
From 1990 to 2000, the population of California can be modeled by P = 29, 816,591(1.0128) where t is the
number of years since 1990.
A. What was the population in 1990?
B. What is the growth factor?
C. What is the annual percent increase?
D. Estimate the population in 2007.
The population is modeled with an exponential equation, and using what we know about exponential equations we will see that:
A) P(0) = 29,816,591B) the growth factor is 1.0128C) 1.28%D) P(17) = 37,013,551.9How to identify the parts of the exponential equation?
Here we have the exponential equation:
P(t) = 29,816,591*(1.0128)^t
A) The population in 1990 will be given by P(0), this is:
P(0) = 29,816,591*(1.0128)^0 = 29,816,591
B) For an exponential:
A*(b)^x
We can rewrite it as:
A*(1 + r)^x
In this case, b is the growth factor, so in our function, the growth factor is 1.0128
C) Using the above notation, the percent increase by year is given by 100% times r, so first let's get the value of r.
r = b - 1 = 1.0128 - 1 = 0.0128
Then the percent increase is: 0.0128*100% = 1.28%
D) The year 2007 comes 17 years after 1990, so we need to evaluate the equation in t = 17, we will get:
P(17) = 29,816,591*(1.0128)^17 = 37,013,551.9

A garden is in the shape of a rectangle, ABCD, and a semicircle.
AD is the diameter of the semicircle.
Carol is going to cover the garden with fertiliser.
A box of fertiliser costs £4.99
Carol has been told that one box of fertiliser will cover 12 m? of garden.
(a) Work out the cost of buying enough fertiliser to cover the garden completely.
Answer:
34.93
Step-by-step explanation:
find area of semicircle=(pi×radius squared)/2=27.7
find area of rectangle=base×height=47.04
74.74=total area
if one box covers 12 how many boxes cover 74.74=6.2283 but you cannot buy .2283 of fertiliser so you round up to 7 boxes
so total cost becomes 7×4.99=34.93
