Answer:
i do believe the answer is 6/7
Answer:
8/5
Step-by-step explanation:
use the formula (y2-y1)/(x2-x1)
(1+7)/(9-4)
8/5
The answer is [ yes; ΔABC ~ ΔFGH by SAS Similarity ]
SAS Similarity states that two triangles have congruent corresponding angles and the corresponding sides have an identical ratio
The angle measure aren't given but the angles look to be the same.
To find the scale factor, divide.
12 / 8 = 1.5
15 / 10 = 1.5
The corresponding sides have an identical ratio.
This proves that option B is correct.
Best of Luck!
Substitute sin(x) = tan(t) and cos(x) dx = sec²(t) dt. We want this change of variable to be reversible, so let's assume bot x and t are bounded between 0 and π/2.
Then we have
Recall the Pythagorean identity,
1 + tan²(t) = sec²(t)
Then
√(1 + tan²(t)) = √(sec²(t)) = sec(t)
and the integral reduces to
Change the variable back to x, so the antiderivative is
Answer:
Step-by-step explanation:
Because base x height gives the area of the rectangle, we can use the same measurements on the parallelogram to compute its area: base x height. (As before, "height" is measured perpendicular to the base, and "base" is whichever side you chose first.)
