Answer:
a = 8, b = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given the exponential function
f(x) = a[tex]b^{x}[/tex]
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
a = 8
f(x) = 8[tex]b^{x}[/tex]
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
[tex]\frac{18}{8}[/tex] = b² , that is
b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )
b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]
Thus
f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

Step-by-step explanation:
13=blue blankets 7=red blankets
First, we need to know how many blankets there are in total.
13+7=20
Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.
13/20
Now, we need to know how many blue blankets there are in percentage.
13/20 = x/100
Next step: 13 times 100 is divided by 20
x= 13(100)÷20
x=1300÷20
x= 65
If x = 8, what is the value of 4x + 6?
I NEED HELP! I’m on a test!!
Answers
Answer:
=38
Step-by-step explanation:
Use substitution :3
4(8)+6=38
substitute x to 8 then calculate!
There you'll get your answer.
the required value of expression 4x + 6 is 38 when x = 8.
If x = 8, what is the value of 4x + 6 to be determine.
In mathematics, it deals with numbers of operations according to the statements.
The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.
Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38
Thus, the required value of expression 4x + 6 is 38 when x = 8.

James is a botanist studying the production of beans by two types of bean plants.
He noticed that the string bean plant produced 30% more beans than the lima bean
plants. Based on James' observation, if the string bean plants produced 130 string
beans, how many lima beans did the lima bean plant produce?
Answers
Answer:
100 lima beans
Step-by-step explanation:
We can write an equation with s = string beans and l = lima beans:
s = 1.3l
We can now plug in 130 = s to get:
130 = 1.3l
We divide both sides by 1.3 and get:
100 = l
That means the lima bean plant produced 100 lima beans
Answer:
91
Step-by-step explanation:
130 * 30% =
130 * 0.3 =
39
130 - 39 = 91
Do these ratios form a proportion 12/16 and 15/20
Answers
Answer:
This is a proportion
Step-by-step explanation:
Cross multiply:
12 * 20 = 16 * 15
Simplifying:
12 * 20 = 16 * 15
Multiply 12 * 20
240 = 16 * 15
Multiply 16 * 15
240 = 240
Add '-240' to each side of the equation.
240 + -240 = 240 + -240
Combine like terms: 240 + -240 = 0
0 = 240 + -240
Combine like terms: 240 + -240 = 0
0 = 0
Solving
0 = 0

the sum of two and a number is less than five
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
Let 'n' be the number. The sum of two and number = 2 + nWe know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
2 + n < 5Let us solve the algebraic expression.
[tex]2+n<5[/tex]
Subtract 2 from both sides
[tex]2+n-2<5-2[/tex]
Simplify
[tex]n<3[/tex]
Thus, the solution is:
[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

2. Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles
hold?
Answers
Answer:
16 1/2 gallons of water.
Step-by-step explanation:
Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.

Jim is making salsa. His recipe calls for 3 1 3 cups of tomato sauce for every 1 6 cups of cilantro. If Jim has 1 cup of cilantro, how many cups of tomato sauce will he need?
Answers
Answer: 20 cups of tomato
Step-by-step explanation:
From the question, we are informed that Jim is making salsa and that his recipe calls for 3 1/3 cups of tomato sauce for every 1/6 cups of cilantro.
If Jim has 1 cup of cilantro, thus simply means that he has multiplied the previous cup of cilantro by:
= 1 ÷ 1/6
= 1 × 6/1
= 6
Therefore, we would also multiply the cups of tomato by 6. This will be:
= 3 1/3 × 6
= 10/3 × 6
= 20 cups of tomato
