Answer:
4 feets
Step-by-step explanation:
Given that :
Height of tree = 20 feets
Shadow of tree = 15 ft
Height of student = 5ft 4 in ; 4 in = 0.3333 foot = 5.3333 feet
Shadow of student = s
Height of tree / shadow of tree = height of student / shadow of student
20 / 15 = 5.33333 / s
Cross multiply :
20 * s = 15 * 5.33333
s = 79.99995 / 20
s = 3.9999975
Shadow of student =, 4 feets

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 82 - 42 ) ( 1/4 )²
On simplifying the equation , we get
A = ( 40 ) ( 1/16 )
A = 40/16
A = 2.5
Hence , the expression is solved and A = 2.5

Quadratic Transformations (photo down below)
Answer: b
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Because the transformation of the quadratic equation is outside of parentheses, it can be concluded that the line is either above or below each other. Next, since we are determining how much higher of lower f(x) is according to g(x), we can determine that it is above since the f(x) is a + and g(x) is a -.

Answer:
[tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]
Step-by-step explanation:
We use the properties of logarithms to write this as a single logarithmic expression. First the exponent property:
2 log(a) + 4 log(b) - log(c) - 3 log(d) =
= log(a^2) + log(b^4) - log(c) - log(d^3) =
and now the multiplication and division properties
= [tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]

The new computer you want to buy costs $749.50. If you wait for it to go on sale for 17% off, what will the sale price be?
Answer:
$622.09
Step-by-step explanation:
The computer is $749.50 and if the computer is 17% off, it means that you only need to pay 83% of the original cost.
749.50/100 = 74.95
74.95*83 = $622.085
Since the thousandth is a 5, round up to $622.09
The sale price is $622.09

Answer:
1. Yes, it does not have a y-intercept, but has slope.
2. No, it has y-intercept.
Step-by-step explanation:
A direct variation relationship has to be able to fill in the equation y=mx. Any direct variation relationship cannot have a y-intercept in it. Therefore, question 1 is a direct variation relationship and question 2 is not a direct variation relationship.

What is the slope of the line
Write an equation in point-slope form of the line that passes through the two given points. Use the point (5,1) to write the equation.
(4, 7) and (5, 1)
A. y + 1 = 6(x-5)
B. y + 1 = 6(x+5)
C. y - 1 = -6(x-5)
D. y + 1 = -6(x-5)
Answer:
c.
Step0-by-step explanation:
you can plug both points into the equations
or you can just write it out using the point slope equation y-y₁=m(x-x₁)
plug in (5,1)
y₁=1 x₁=5
slope is difference of y/difference of x
m=(7-1)/(4-5)=-6
plug in to y-y₁=m(x-x₁) and you get
y - 1 = -6(x-5)
