Answer:
product
Step-by-step explanation:
Answer:
Multiply by 3 on both sides of the equation.
2.78 × 3 = 8.34, so t = 8.34.
Substitute 8.34 for t to check the solution.
Step-by-step explanation:
To solve the equation = 2.78
we will use the steps below to solve this equation;
First, multiply by 3 on both-side of the equation. That is;
× 3= 2.78 × 3
On the left hand side of the equation 3 will cancel-out 3, leaving us with just t while 3 will be multiply by 2.77 on the right-hand side of the equation to give 8.34
t = 8.34
we can further substitute 8.34 for t to check the correctness of the solution
that is;
= 2.78
R
Answer: Yes.
Step-by-step explanation:
It forms an obtuse triangle.
Answer:
The solutions 
are 
and the x-intercepts of 
are 
Step-by-step explanation:
Finding the solutions to 
means finding the roots, a root is where the function is equal to zero.
The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero.
To find the roots you need to:
Rewrite the equation with 
and 
Solve by factoring
Using the Zero factor Theorem: if ab = 0 then a = 0 or b = 0 (or both a = 0 and b = 0)
The solutions to the quadratic equation are:
Substitute back , solve for x
Apply the difference of squares formula
Using the Zero factor Theorem: if ab = 0 then a = 0 or b = 0 (or both a = 0 and b = 0)
The solutions are:
Because two of the solutions are complex roots the only x-intercepts are
Answer:
5.25 feets
Step-by-step explanation:
Given that:
Height of Salem Sue = 38 feets
Height of Salem Sue's shadow = 57 feets long
Height of child standing next to the statue = 3.5 foot tall
Length of the child's shadow =?
Let lenght of child's shadow = s
IF;
38 Feets tall = 57 feets lenght
3.5 feets tall = s feets long
Cross multiply :
38 * s = 57 * 3.5
38s = 199.5
38s / 38 = 199.5 /38
s = 5.25
Hence, length of the child's shadow will be 5.25 feets long
