2 answers:
Answer:
C) 6 inches
Step-by-step explanation:
Given function:
The function compares plant height in inches to the age of plant in weeks.
So, we can say
represents height of plant in inches.
represents age of the plant in weeks.
In order to predict the height of the plant in 5 weeks, we will plugin in the given function and evaluate
⇒
⇒
⇒ inches
Thus the approximate height of plant in 5 weeks would be inches

Answer: The area of the parallelogram is:
_______________________________________________________
in² = 1174 ⅛ in² = 1174.125 in² .

Explanation:
_______________________________________________________
Area of a parallelogram:
_______________________________________________________
A = base * height = b * h ;
From the figure (from the actual "question"):
_______________________________________
b = 50.5 in.
h = 23.25 in.
____________________________________________________________
Method 1) A = b * h =
= (50.5 in) * (23.25 in) = 1174.125 in² ; or, write as: 1174 <span>⅛ .
</span>____________________________________________________________
Method 2) A = b * h =
= (50 ½ in) * (23 <span>¼ in) =
= (</span>
in) * (
<span> in) ;
</span>___________________________________________________________
Note: "50 ½ " = [(50*2) + 1 ] / 2 = ;
Note: "23 ¼ " = [(23*4) + 1 ] / 4 = ;
____________________________________________________________
→ A = ( in) * ( in) ;
→ A =
in² = in² ;
→ A = (9393/8) in² =
→ A = in² = 1174 ⅛ in² = 1174.125 in² .

Answer:
13 and -14 satisfy this condition
Step-by-step explanation:
Let's represent that number as x
and the square of x is x^2
So,
x + x^2 = 182
Subtract 182 from both sides
x + x^2 - 182 = 182 - 182
x + x^2 - 182 = 0
rearrange the quadratic equation
x^2 + x -182 = 0
let's use the quadratic formula
or
a = 1, b = 1, c = -182
or
or
or
or
or
13 or - 14
Lets check
13 + 13^2 = 13 + 169
= 182
Also,
-14 + (-14^2) = -14 + 196
= 182
