Two forces of 90 newtons and 58 newtons act simultaneously on an object. The angle between the two forces is 57°. Find the magni
Vanyuwa [196]

Answer:

131.0 N

Step-by-step explanation:

Let the 90 N force is acting a horizontal force on the object

Horizontal force = 90 + 58sin33

Vertical force = 58cos33

∴The resultant force = √(90 + 58sin33)² + (58cos33)²

= 131.0 N

Lena [83]

Answer:

t = total people

m = men

w = women

w / m = 3  So A) w = 3 * m

B) w  = m + 200

multiplying A) by minus 1

A) -w = -3m

B) w = m + 200

Adding the 2 equations

0 = -2m + 200

2m = 200

m = 100 Since there are 200 more women than men then there are

300 women

Total people = 100 + 300 = 400

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
Whitepunk [10]

The change represents decay and the percentage decrease is 2.9%

<h3>Exponential function</h3>

The standard exponential function is expressed as y = ab^x

where:

a is the initial

b is the rate

If the value of b is less than 1 hence the function is decay and if greater than 1, the function is growth

GIven the expoenential function y=100(0.971)^x

Since the value of b = 0.971 < 1, hence the function is a decay.

The percentage decrease = 1 - 0.971 = 2.9%

Hence the percentage decrease is 2.9%
