Find the slope of the tangent to y= -7Sin(x)+2cos(x) at x= 3π/4

BaLLatris [955]

Y = -7sin(x) + 2cos(x)
y = -7sin(3π/4) + 2cos(3π/4)
y = -7sin(9.42/4) + 2cos(9.42/4)
y = -7sin(2.355) + 2cos(2.355)
y = -7(0.03698381721) + 2(0.9993158646)
y = -0.2588867205 + 1.998631729
y = 1.739745009

Malcolm has 225 yards of yarn to make 100 bracelets. Suppose the total length of the yarn stayed the same, but instead of Malcol

ANTONII [103]

Given :

Length of yarn, l = 225 yards.

Number of bracelets he made, n = 1000 .

To Find :

How long will the yarn be for each bracelet.

Solution :

Let, length of yarn used in each bracelet is x.

So,

$x = \dfrac{Total\ length \ of yarn}{Number \ of \ bracelets\ made}\\\\x = \dfrac{225}{1000}\\\\x = 0.225 \ yards$

Therefore, length of yarn used in each bracelet is 0.225 yard.

1. This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this composite figure? S

White raven [17]

Answer:

29.92 m² (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2$

$\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{ m}^2$

Area of rectangle = width × length

⇒ area = 4 × 5.5 = 22 m²

Total area = area of sector + area of rectangle

⇒ total area = $\dfrac{121}{48}\pi +22$ = 29.91943148... = 29.92 m² (nearest hundredth)
