F(x)=15^3 so that means it’s 15•15•15 which equals 3,375.

Evaluate 3/5 - 3/10 and explanation thanks

Setler [38]

It would be 3/10 because you have to create a common denominator. That would be 10. 3x2=6 and 5x2=10, so 3/5 would become 6/10, which is equivalent. If you kept the denominators the same and subtracted the numerators, you would get 3/10.

I NEED HELP PLEASE, THANK YOU!

Answer:

$\sqrt{37}$

Step-by-step explanation:

To find the distance between a point (m, n ) and the line

Ax + By + C = 0

d = $\frac{|Am +Bn+C|}{\sqrt{A^2+B^2} }$

Here (m, n) = (6, 2) and rearranging the line

6x - y + 3 = 0 ← in general form

with A = 6, B = - 1 and C = 3 , then

d = $\frac{|6(6)-1(2)+3|}{\sqrt{6^2+(-1)^2} }$

= $\frac{|36-2+3|}{\sqrt{36+1} }$

= $\frac{37}{\sqrt{37} }$

Rationalise the denominator by multiplying numerator/ denominator by $\sqrt{37}$

= $\frac{37}{\sqrt{37} }$ × $\frac{\sqrt{37} }{\sqrt{37} }$

= $\frac{37\sqrt{37} }{37}$ ← cancel 37 on numerator/ denominator

= $\sqrt{37}$

Find(4) when f(x)=4x^2-3x+3

zimovet [89]

Assuming x = 4, replace each x in the equation with 4:

$4(4)^{2} - 3(4) + 3$

Solve each term in parentheses:

$4(4)^{2}$
$4^{2} = 16$
$4 \times 16 = 64$

$-3(4)$
$-3 \times 4 = -12$

Your equation should now look like this:

$64 - 12 + 3 = 55$

f(4) will equal 55.
