Answer:

1) 5.9

2) 8.1

3) 54

Step-by-step explanation:

A is opposite, so we have sine 36=a/10

sine 36(10)=a

a=5.9

B is adjacent, so we have cosine 36=b/10

cosine 36(20)=b

b=8.1

Angles of a triangle add to 180

we have a angle of 36 and a right angle which is 90

36+90=126

180-126=54

Use the arc length formula and the given information to find r.. s = 16 cm, θ = 48°; r = ?

saveliy_v [14]

Answer:

The value for r is 19.1 cm

Step-by-step explanation:

We have been given that s = 16 cm, θ = 48° and we have to find the radius r.

We know the relation

$\theta=\frac{s}{r}\\\\r=\frac{s}{\theta},\text{ where }\theta \text{ is in radian}$

Hence, first of all convert the angle in radian

θ = 48°= 0.837758 radian

Therefore, we have

$r=\frac{16}{0.837758}\\\\r=19.1\text{ cm}$

Answer:

$20.85 less.

Step-by-step explanation:

City sales:

7% tax = 48.65

total bed cost = $743.65

Nearby City:

4% tax = 27.8

total bed cost = $722.8

city sale - nearby city

743.65 - 722.8

=20.85

What is the x-coordinate of the vertex of the parabola whose equation is y = 3x² + 9x?

saveliy_v [14]

Answer: -3/2

Step-by-step explanation:

The axis of symmetry, and thus the x-coordinate of the vertex, is given by $x=-\frac{b}{2a}$

So, the answer is $x=-\frac{9}{2(3)}=\boxed{-\frac{3}{2}}$
