Step-by-step explanation:
Sum of angles in a triangle = 180°
Hence Angle 1 = 180° - 24° - 37° = 119°.
Answer:
∠ CDB = 43°
Step-by-step explanation:
Angles subtended at the circumference by the same arc are congruent.
The arc CB subtends both ∠ CAB and ∠ CDB , thus
∠ CDB = ∠ CAB = 43°
Just to go into more detail than I did in our PMs and the comments on your last question...
You have to keep in mind that the limits of integration, the interval
, only apply to the original variable of integration (y).
When you make the substitution
, you not only change the variable but also its domain. To find out what the new domain is is a matter of plugging in every value in the y-interval into the substitution relation to find the new t-interval domain for the new variable (t).
After replacing
and the differential
with the new variable
and differential
, you saw that you could reduce the integral to -1. This is a continuous function, so the new domain can be constructed just by considering the endpoints of the y-interval and transforming them into the t-domain.
When
, you have
.
When
, you have
.
Geometrically, this substitution allows you to transform the area as in the image below. Naturally it's a lot easier to find the area under the curve in the second graph than it is in the first.
Answer:
y= 8.5x - 10
Step-by-step explanation:
I think it is substracting because it's how much remains, if its wrong it could either be 10x - 8.5 or 8.5x + 10
