Answer:
[tex](f\circ g)(-5)=85[/tex]
Step-by-step explanation:
We are given:
[tex]\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x[/tex]
And we want to find:
[tex](f\circ g)(-5)[/tex]
This is equivalent to:
[tex]\displaystyle =f(g(-5))[/tex]
So, we will evaluate g(-5) first, which yields:
[tex]\displaystyle g(-5)=(-5)^2+(-5)=25-5=20[/tex]
So:
[tex]=f(g(-5))=f(20)[/tex]
Then:
[tex]\displaystyle f(20)=4(20)+5=80+5=85[/tex]
Therefore:
[tex](f\circ g)(-5)=85[/tex]

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?
The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³

Marilyn collects old dolls. She purchases a doll for $450. Research shows this doll's value will increase by 2.5% each year. Write an equation that determines the value, V, of the doll t after purchase.
Answer:
V = 450 + 0.025t
Step-by-step explanation:
What we know is that Marilyn purchases a doll for $450 dollars, and the value will increase by 2.5% each year. Now that we know this, this means we need an addition equation. We know 450 is being add to the 2.5% increase so the equation is V = 450 + 0.025t. (I put 2.5% as a decimal (0.025))
The equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
What is compound interest?Compound interest is an interest accumulated on the principal and interest together over a given time period. The compound interest is calculated, after calculating the total amount over a period of time, based on the rate of interest, and the initial principal.
Formula of Compound Interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Where,
A = Final amount
P = Initial principal
r = Rate per annum
n = Time in years
According to the question
Marilyn purchases a doll for = $450
i.e, Initial Principal (P) = $450
Doll's value will increase each year by = 2.5%
i.e, Rate per annum = 2.5%
Value (V) of the doll after purchase = Final amount (A)
(t) = Time in years (n)
Now, Formula of compound interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Substituting the values in formula
[tex]V = 450 (1+\frac{2.5}{100} )^{t}[/tex]
[tex]V = 450 (1+{0.025}{} )^{t}[/tex]
[tex]V = 450 ({1.025}{} )^{t}[/tex].
Hence, equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]

Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into pieces that are 16 inches long. What is the greatest number of 16-inch pieces that Mr. Trainer can cut from the two wooden boards? (1 foot = 12 inches)
Answer:
12
Step-by-step explanation:
Length of one of the boards = 8 feet
Converting to inches
[tex]1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}[/tex]
One cut is 16 inches
So, we divide the length of the board by 16
[tex]\dfrac{96}{16}=6[/tex]
So, one board is cut into 6 pieces.
The other board is also 8 feet long.
So, the number of pieces the other board is cut into is also 6.
Hence, a total of [tex]6+6=12[/tex] pieces of each 16 inches long can be cut from the two boards.
