We have the equation f(x)=6x-5 to start with
Now in order to answer the question we have to know that f(5) is the same thing as setting x=5 and solving for f(5)

(A) f(5) = 6(5) - 5 = 30 - 5 = 25
(B) f(-3) = 6(-3) - 5 = (-18) - 5 = -23

So f(5) = 25 and f(-3) = -23

La base de una pirámide es una región cuadrada que tiene 10k de lado; si la altura de la pirámide es de 12k, Calcule el volumen

mart [117]

Side of base of square, a = 10 km.

Height of pyramid , h = 12 km.

Volume of pyramid is given by :

$V=\dfrac{a^2h}{3}\\\\V=\dfrac{10^2\times 12}{3}\ km^3\\\\V=400\ km^3$

Surface area is given by :

$S.A=2ah + a^2\\\\S.A=(2 \times 10\times 12) + 10^2\ km^2\\\\S.A=340\ km^2$

Therefore, volume and surface area are 400 km³ and 340 km² respectively.

Hence, this is the required solution.

If the original quantity is 12 and the new quantity is 15, what is the percentage increase

beks73 [17]

Answer:

25%

Step-by-step explanation:

Given data

original quantity =12

new quantity =15

% increase= new-original/original *100

% increase= 15-12/12 *100

% increase= 3/12 *100

% increase=0.25 *100

% increase=25%

hence the increase is 25%
