answer : 3/8 or .375
8x=3
divide both sides by 8
x=3/8 or .375

Which properties are present in a table that represents an exponential function in the form y=b^x when b > 1? I. As the x-values increase, the y-values increase. II. The point (1, 0) exists in the table. III. As the x-values increase, the y-values decrease. IV. As the x-values decrease, the y-values decrease, approaching a singular value. I and IV I and II II and III III only
Answer:
Properties that are present are
Property I
Property IV
Step-by-step explanation:
The function given to us is where b > 1
Let us take a function, for example,
Now, let us check the conditions before we continue:
I. When the x-values increases, the y-values will also increase.
Let us put some values:
y = 2 ^ 1
which results to y = 2
and
y = 2 ^ 2
which results to y = 4
So this is definetly TRUE.
II. The point: (1,0) is in the table.
Ok, now let us put 1 into x and try to see if it gives us 0
y = 2 ^ 1
y = 2
So this is surely FALSE.
III. As the x-value increase, the y-value decrease.
We have already seen that as x increase, y also increase in part I.
So this is FALSE.
IV. as the x value actually decrease. Now, the y values decrease approaching a singular value.
The exponential function of this form will NEVER go to 0 and is NEVER negative. So as x decreases, y also decrease and came to a value (that is 0) but never becomes 0.
This is TRUE.
Therefore, Option I and Option IV are true.

In that school, what is the ratio of the number of students who like math to the number of students who like science? (see picture)
Answer: 1/2:1/3
I hope this helps
Step-by-step explanation:
In the problem it says 1/2 of the students in the school like math, and it also says in the problem that 1/3 of the students in the school like science. The question is asking for a ratio of students who like math to students who like science, so now the only thing you need to do is input those 2 numbers in the order that they want it in. Which is 1/2:1/3. And don't forget that the colon : is what you always put in between the two numbers.

Plz help ASAP!! A surgical technique is performed on eight patients. You are told that there is an 80% chance of success. Find the probability that the surgery is successful for fewer than two patients. Please show your work. Hint: the answer is 0.000084.
Answer:
This is a fairly simple binomial distribution. We know it's binomial, because we're looking for a "fixed" number of patients, not the "first" like a geometric.
You can use your calculator:
binomcdf(n,p,Kr)
n=population, p=probability, Kr=number you're looking for
binomcdf(8,.8,1)
We have to do 1, not 2, because it says fewer than 2, which means 1.

A polygon is shown:
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units. (Input whole numbers only, such as 8.) (5 points)
Answer: 4
We're talking about the right part.
OP = RQ - NM = 7 - 3 = 4
PQ = MR - NO = 3 - 2 = 1
Area(OPQ?) = 4×1 = 4
Answer: 4
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is 4 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
A polygon is given in the question, as shown
The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units.
We have to determine the fill-in-the-blank.
As per the given figure, we can see that
OP = RQ - NM = 7 - 3 = 4
PQ = MR - NO = 3 - 2 = 1
Required area of rectangle = 4 × 1 = 4
Hence, the required fill-in blank will be "4".

Solve the equation for x, in simplest form x+3/8=1/4
Answer:
x = -1/8
Step-by-step explanation:
x + 3/8 = 1/4
Subtract 3/8 from both sides.
x = 1/4 - 3/8
The LCD is 8.
x = 2/8 - 3/8
x = -1/8
Answer:
1/8
Step-by-step explanation:
1/4 = 4/8
4/8-3/8 = 1/8
0.25- 0.375 = 0.125
0.125 = 1/8

9 in.
8 in.
7
in.
Answer:
Step-by-step explanation:
To calculate the volume of a pyramid with a rectangular base, find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Take that result and divide it by 3 to calculate the pyramid's volume!

What is the volume of the composite solid?
Answer:
Step-by-step explanation:
In order to find the volume of a composite solid, one needs to identify the different parts it is made of. This decomposition allows working out the volume of each part independently. The volume of the composite solid is simply the sum of the volumes of its parts.

Harry took out an 80/20 mortgage to buy a house costing $175,000. The first
(80%) mortgage has an interest rate of 4.75%, and the second (20%)
mortgage has an interest rate of 7.525%. Both the first mortgage and the
second mortgage are 30-year fixed-rate mortgages. What is his total
mortgage payment for this house?
A. $730.31
B. $975.63
C. $245.32
D. $805.87
Answer:
Its b got it correct
The total monthly mortgage payment for the house is $975.63
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
The principle amount is $175000
80% of 175000 is = = $140000
20% of 175000 is = = $35000
Emi formula is :
p*r*(1-r)^n/(1-r)^n-1
For 1st part:
p = 140000
r = 4.75/12/100=0.00395
n = 360
Putting values in formula we get
= $729.508
For 2nd part:
p = 35000
r = 7.525/12/100=0.00627
n = 360
Putting values in formula we get
= $245.301
Adding both the monthly payments:
974.809 dollars
This is closest to option A.
So, option A is the answer.
And for 30 years the mortgage payment will be = 351226.80 dollars
Hence, The total monthly mortgage payment for the house is $975.63.
