So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
Hi there!
Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.
Anyways,
tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75
cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78
For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...
angleC=180-(90+50)
angleC=180-140
angleC=40°
Answer:
(a-b)^3 =
Step-by-step explanation:
(a-b)^3 = (a-b)(a-b)(a-b)
According to the perfect cube formula (a-b)^3 =
And there you have it! The perfect cube formula already solved your equation!
I think that the interval that is always increasing is interval number 1.
Answer:
x ≠-8 x ≠ -2
Step-by-step explanation:
We cannot divide by zero, so the denominator cannot equal zero
X^2+6x-16≠0
Factor
(x+8) (x-2) ≠0
Using the zero product property
(x+8) ≠0 (x-2) ≠0
x ≠-8 x ≠ -2
