1 answer:
Nastasia [14]2 years ago
6 0

Answer:

f(-2.75)=-1

Step-by-step explanation:

Here we are given a Greatest Integer Function . The characteristic of this function is that it when operated , gives you the greatest integer it has near to it.

Hence if we have any greatest integer function f(x)=[x] , for x = -2.75

[-2.75]=-2 , as -the greatest integer near to -2.75 is -2 as -3<-2

Now coming back to our problem, our function is

f(x)=[x]+1

Hence for x=-2.75

f(x)=[-2.75]+1

as we discussed above [-2.75]=-2

Hence

f(-2.75)=-2+1

f(-2.75)=-1

KLMN is a parallelogram,
Aleonysh [2.5K]

Answer:

Ok soo.

Step-by-step explanation:

sum of two adjacent angles of parallelogram is 180

so angle K + angle L = 180

as AK bisects angle K and LA bisects angle L

so, angle AKL + angle ALK = 180 /2 = 90

in triangle AKL,

angle AKL + angle ALK+angle KAL = 180(sum of all angles in triangle = 180)

so, from above two equations,

angle KAL = 90

Lyrx [107]
13.1 an hour, 34 hours a week
13.1 x 34 = 445.4 a week
to find out how many weeks, divide 4300 and 445.4 which is 9.65 weeks, which is technically 10 weeks

it would take 10 weeks to earn 4300

Based on the ratios shown ion the double number line, what is the cost for 5 pounds of almonds? :)
denis-greek [22]
I found the answer to this by first dividing 34 by 4 to get 8.5. We already know what 4 divided by 4 is. For every one pound of almonds, it costs $8.50. Since we know that we need to find out how much it costs for 5 pounds of almonds, we simply multiply 8.5 by 5 to get 42.5. It costs $42.50 to buy 5 pounds of almonds.
