P varies directly as I. If P is 0.5 when I is 4, find P when I is 6

Mathematics

Softa [21]3 years ago
4 0

Answer:

P = 0.75

Step-by-step explanation:

Given that P varies directly as I then the equation relating thenm is

P = kI ← k is the constant of variation

To find k use the condition P = 0.5 when I = 4, thus

k = \frac{P}{I} = \frac{0.5}{4} = 0.125

P = 0.125I ← equation of variation

When I = 6, then

P = 0.125 × 6 = 0.75

Triangle MNP has vertices N(2, 2) and P(0, –2). The triangle is symmetric about the y-axis. What is the approximate measure of t
Evgesh-ka [11]
Point M of the triangle is (-2,2) to make triangle MNP as shown in the attached image

Triangle MNP has a base of 4 units and a height of 4 units. We can work out the angle x and angle y using trigonometry ratio

We use tan ratio to find both angles

Tan (x) = \frac{opposite}{adjacent}
Tan(x)= \frac{4}{2}
Tan(x)=2
Tan^{-1}(2)=63.43494882
Angle x=63.43

Tan(y)= \frac{opposite}{adjacent}
Tan(y)= \frac{2}{4}
Tan^{-1}(0.5)=26.56505118
Angle y=26.6

Angle MNP = Angle NMP = 63.43 degrees (this is based on the fact that the triangle is an isosceles triangle)

Angle MPN = 2×26.6 = 53.2 degrees (we multiply by 2 as angle y is only a half of angle MPN - as shown in the diagram)

-1/5(x-4)=-2 how do you solve this equation
m_a_m_a [10]
Multiple both sides by 5/1 and get

-1/1 • (x-4) = -10/1

divide the numbers and get

-1 • (x-4) = -10

remove the parentheses

- x-4 = 10

move the constant to the right

-x = -10-4

calculate

-x = -14

change the signs

x= 14
