I have 90% after about 75%

The lowest grade he could earn is 120% of the grade at the end of the semester.

The following statement is given:

I have 90% after about 75% of the semester.

We are asked to find the lowest grade by the end of this semester.

<h3>What is Percentage?</h3>

A percentage is a number expressed as a fraction of 100.

- 50% = 50/100 = 1/2

- 25% = 25/100 = 1/4

- 20% = 20/100 = 1/5.

We can write this statement "I have a 90% grade after about 75% of the semester" as:

90% grade = 75% semester.............(1)

By the end of the semester means at 100% semester.

Multiplying equation (1) by 100/ 75 on both sides of the equation.

We get,

(100/75) x 90% grade = (100/75) x 75% semester

(100 x 90)/75 % grade = 100% semester

120% grade = 100%

Thus the lowest grade he could earn is 120% of the grade at the end of the semester.

Given :-

Line p has an equation of y = 5/3x - 4 .
Line q includes point (-10,-3) and is perpendicular to the line p .

To Find :-

The equation of line q .

Solution :-

The equation of the line p is ,

$\sf\blue{\longrightarrow}$ y = 5/3x - 4

On comparing to slope intercept form of the line which is y = mx + c , we have ,

$\sf\blue{\longrightarrow}$ m = 5/3

Now as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be ,

$\sf\blue{\longrightarrow} m_{\perp} = -3/5$

Now here the line q passes through the point (-10,-3) . So on using the point slope form of the line we get ,

$\sf\blue{\longrightarrow} y - y_1 = m(x-x_1)$

$\sf\blue{\longrightarrow}$ y - (-3) = -3/5[ x-(-10)]

$\sf\blue{\longrightarrow}$ y +3 = -3/5(x+10)

$\sf\blue{\longrightarrow}$ y+3 = -3/5x - 6

$\sf\blue{\longrightarrow}$ y +9 = -3/5x

$\sf\blue{\longrightarrow}$ y = - 3/5x - 9

Hence the required answer is y = -3/5x - 9 .

What’s the answer??(SOMEONE PLEASE HELP ME)

Ket [755]

We know that :

If f(x) and g(x) are Two Functions Defined under same Domain, then Composite Function : (f o g)(x) = f(g(x))

Given : f(x) = $\frac{2}{x + 3}$ and g(x) = $\frac{1}{2x}$

⇒ (f o g)(x) = f(g(x))

⇒ $(f\;o\;g)(x) = f(\frac{1}{2x})$

⇒ $(f\;o\;g)(x) = \frac{2}{\frac{1}{2x} + 3} = \frac{4x}{1 + 6x}$

1st Option is the Answer
