The answer
<span>to eliminate t from the parametric equations x=t^2+3 and y=4t
we have t²= x-3, and then t= sqrt(x-3), but we know that y=4t, which implies t=y/4. We only substitute the value of t by y/4, so </span>t= sqrt(x-3) wich is equivalent to y/4=sqrt(x-3), so at last y= 4 sqrt(x-3). t exactly eliminated.
so the true answer is
<span>D)She should first substitute y for t before solving.</span>
Hello!
The angles are supplementary meaning they add to 180°
a + 2a + 3 = 180
Combine like terms
3a + 3 = 180
Subtract 3 from both sides
3a = 177
Divide both sides by 3
a = 59
the answer is 59°
Hope this helps!
Answer: 18.774 or rounded off 18.8 percent of her weight is fat.
Answer:
B no
Step-by-step explanation:
If (n - 10) is a factor then if the polynomial equals zero when evaluated for 10 it is a factor
10³ - 17(10)² + 61(10) + 92
= 1000 - 1700 + 610 + 92
= 2 ≠ 0
Then ( n - 10) is not a factor of the polynomial
Answer:
346 cm²
Step-by-step explanation:
<u><em>Area of square:</em></u>
Area =
A = 20*20
A = 400 cm²
<u><em>Area of rectangle:</em></u>
Length = 3 cm
Width = 20-2 = 18 cm
<u><em>Now, The Area:</em></u>
Area =
Area = 3 * 18
Area = 54 cm²
<u><em>Now, The difference in their areas:</em></u>
=> 400-54
=> 346 cm²
