Sorry for all the math questions but I do not understand this at all. someone explain and write the equation for me please?? they are the exact words... doesn't make sense to me:the sum of three times a number (z) and 15 is equal to 21.

Answers

Answer 1

Answer: 3Z + 15 = 21 equation

1. solution
3Z + 15 = 21
3Z = 21 - 15
3Z = 6 [:3
Z = 2

2 solution
3Z + 15 = 21 [:3
Z + 5 = 7
Z = 7 - 5 = 2

Limits

Right-Side Limit: $\displaystyle \lim_(x \to c^+) f(x)$
Left-Side Limit: $\displaystyle \lim_(x \to c^-) f(x)$

Graphical Limits

Step-by-step explanation:

If we graph the function, we can see that as we approach 3 from the left, we go towards negative infinity.

∴ $\displaystyle \lim_( \to 3^-) (1)/(x - 3) = -\infty$

In triangle ABC, c = 8, b = 6, and ∠C = 60°. sin∠B = _____

Answers

Answer:

sin∠B=0.649°

Step-by-step explanation:

Given: In triangle ABC, c = 8, b = 6, and ∠C = 60°.

To find: sin∠B

Solution: using the sine formula that is $(SinA)/(a)=(SinB)/(b)=(SinC)/(c)$ , we get

$(SinA)/(a)=(SinB)/(6)=(Sin60^(\circ))/(8)$

Taking the second and third equality, we get

$(SinB)/(6)=(Sin60^(\circ))/(8)$

⇒ $(SinB)/(6)=((√(3))/(2))/(8)$

⇒ $(SinB)/(6)=(√(3))/(16)$

⇒ $SinB=\frac{√(3){*}6}{16}$

⇒ $SinB=(3√(3))/(8)$

⇒ $SinB=0.649^(\circ)$

Thus, $SinB=0.649^(\circ)$ .

Hello,

sin B/b=sin C/c
