Mathematics

Ugo [173]3 years ago
4 0

Answer: 8

Step-by-step explanation: In this problem,

we're asked to find f(-4) or the value of the function when x = -4.

To find the value of the function when x = -4,we simply plug in a -4 for

the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.

So f(-4) = 8.

A. 16x11 = 176 + 30x8.75 = 262.5. 176+262.5 = 438.5. Not 470
B. 20x11 = 220 + 26x8.75 = 227.5. 220+227.5 = 448. Not 470
C. 30x11 = 330 + 16x8.75 = 140. 330+140 = 470. C. is the correct answer
D. 31x11 = 341 + 15x8.75 = 131.25. 341+131.25 = 472.25 Not 470

A number, n, is multiplied by - 5/8. The products is - 0.40 What is the value of n? It would also help if you would explain how
Kay [80]
I'm not sure if those numbers are negatives or thats just a hyphen but:

N(-5/8)=-0.40

Division is always the opposite of multiplication

-0.40/(-5/8)=0.64

N=0.64

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual
zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle A=a\cdot b assuming a=600km, \ b=450km and get A=600\cdot 450=270000km^2 which is an actual area of Colorado
