A function is given: f (x) = 2x + 3
What is the value of f(-2)?
Answers
Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
A collection of all points in the plane of the form (x, f(x)) is the graph of a function f. The graph of f is defined as the graph of the equation y = f(x).
Find function:[tex]\to f (x) = 2x + 3[/tex]
[tex]\to f(-2) =?[/tex]
Putting the value "-2 " into the above given method:
⇒ f(-2) = 2(-2) + 3
⇒ f(-2) = -4 + 3
⇒ f(-2) = -1

Altogether, 360 schoolchildren sit down for their exams.
Five percent of them have one pen. Of the remaining 95
percent, half of them have two pens and the other half
have none. How many pens do the children have between
all of them?
HEL MEEEE
Answers
Answer:
A esta así no puedo xd ._.
Total Pens, owned by all students between all of them = 360
Percentage wise calculation of Pens
Total children = 360
Students having one pen = 95% of 360 = 18
Remaining 95% = 360 - 18 = 342
Half of remaining ie 342 = 171, have two pens
Other half of remaining ie 171 have no pens
Total pens, all children have between all of them = Summation (number of students x number of pens)
= (18 x 1) + (171 x 2) + (171 x 0)
= 18 + 342
= 360

feet long, how many inches did Mao raise the end of the treadmill from the floor to the nearest tenth of an inch?
Answers
Answer:
5.2 inches
Step-by-step explanation:
We can use trigonometry for this. We know that sin = opposite/hypotenuse so opposite = hypotenuse sin. If we want the answer in inches we set the hypotenuse to inches 5 ft = 60 inches. We just use 60 sin 5 degrees to get to our answer.

Select all that are equivalent to sin∠GFH
Answers
Answer:
I think sin<GEJ IS equivalent to sin∠GFH
All that are equivalent to sin∠GFH is
D) cos(<EGJ)
"Corresponding angles"sin(<GEJ)cos(<FGH)cos(<EGJ)
From the image JE and HF are parallel.
So angle GFH and angle GEJ are corresponding angles.
So they are equal.
so, sin(<GFH) = sin(<GEJ).
From triangle GFH, <GFH+<FGH = 90.
So, sin(<GFH) =cos(<FGH).
Again <FGH = <EGJ.
So, sin(<GFH) =cos(<EGJ)
All that are equivalent to sin∠GFH is cos(<EGJ).
Thus, the correct answer is D.
