Jasmine really wants to make an A in her college math class. The class has 6 exam grades that make up the final grade. So far, she has made an 83, 94, 96, 85, and a 81. Is it possible for her to make an A in the class if the cut off for an is 90 and the highest possible grade on a test is 100?

Answers

Here’s how I would do this.

Multiply .90 (90 percent) by 600 (total points all semester) to see how many points she must earn. You’ll get 540.

Add the scores she’s got already and subtract from 540.

I get 439. She needs 540 and the most she could possibly make is 539.

So no...unless her teacher rounds. :)

Im having troubles. Can some 1 explain in complete explanations and all expressions.

Answers

{x,y} = {4, -3}

Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 4y + 16

// Plug this in for variable  x  in equation [1]

  [1]    (4y+16) + y = 1

  [1]    5y = -15

// Solve equation [1] for the variable  y  

  [1]    5y = - 15

  [1]    y = - 3

// By now we know this much :

   x = 4y+16

   y = -3

// Use the  y  value to solve for  x  

   x = 4(-3)+16 = 4

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (2 points)


f of x equals eight divided by x and g of x equals eight divided by x

Answers

Answer:

we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x

Step-by-step explanation:

We need to confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

We have

[tex]f(x)= \frac{8}{x}\\g(x)=\frac{8}{x}[/tex]

Now, finding f(g(x))

Put x = 8/x in f(x)

[tex]f(g(x)) =\frac{8}{\frac{8}{x} }\\=8\div \frac{8}{x}\\=8 \times \frac{x}{8}\\=x[/tex]

So, we get f(g(x))=x

Now, find g(f(x))

Put x = 8/x in g(x)

[tex]g(f(x)) =\frac{8}{\frac{8}{x} }\\=8\div \frac{8}{x}\\=8 \times \frac{x}{8}\\=x[/tex]

So, we get g(f(x)) = x

Therefore we can say that f and g are inverses of each other because f(g(x)) = x and g(f(x)) = x

Answers

Answer:

78 m

Step-by-step explanation:

We need to use the Pythagorean theorem, [tex]a^{2} + b^{2} = c^{2}[/tex].

Substitute in [tex]a[/tex] and [tex]b[/tex].

[tex]30^{2} + 72^{2} = c^{2}[/tex]

Simplify.

[tex]900 + 5184 = c^{2}[/tex]

Add.

[tex]6084 = c^{2}[/tex]

Square root both sides.

[tex]78 = c[/tex]

The hypotenuse is 78 m long.

find c:

a² plus b² = c

72² plus 30²=c

5I84 plus 900

6084

now square root that
