If f(x)=7-3x and g(x)=3x-7, what is the value of f(1)-g(1)?

1 answer:

6 0

Substitute 1 for x in each of your equations.

f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4

Then subtract g(x) from f(x):
3-(-4)
=7

What is the total surface area of a cylindrical tank having

Answer:

Could be C) or D) None of these, 29688.05cm^2

Step-by-step explanation:

Did the question to round off to any numbers?

Formula for cylinder's T.S.A: 2 π r h + 2 π r^2

Diameter= 2 x radius

Radius = 70cm / 2 = 35cm

Height -> need to convert m to cm -> 100cm

Substitute these values into the formula:

2 x π x 35 x 100 + 2 x π x (35)^2 = 29688.05cm^2

#82 will give brainliest to best answer!

Fofino [41]

Answer:

$\frac{6}{k-6}$

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ ÷ $\frac{(k-6)^2}{k(k-6)}$ × $\frac{6(k-10)}{k(k + 6)}$ . We know that division is simply multiplication by the reciprocal, so that whole equation will turn into $\frac{(k+6)(k-6)}{(k-6)(k-10)}$ × $\frac{k(k-6)}{(k-6)^2}$ × $\frac{6(k-10)}{k(k+6)}$ . Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into $\frac{6}{k-6}$ which is our final answer, as it cannot be simplified further.

Hope this helped! :)

What is the answer to this question please explain (picture included)

Easy peasy
just use PEMDAS and some exonential laws

$(x^{m})(x^{n})=x^{m+n}$
$(x^{m})^{n}=x^{mn}$
$(ab)^{m}=(a^{m})(b^{m})$

also another is $x^{\frac{m}{n}}=\sqrt[n]{x^{m}}$

so

$[3(2a)^{\frac{3}{2}}]^{2}$ =
$(3^{2})((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{6}{2})$ =
$(9)((2a)^{3})$ =
$(9)(8a^{3})$ =
$72a^{3}$
