If f(x)=2x-3 find the following
f(7)=
f(-2)=
f(-4)=
Answers
The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.
What is a function?
A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given,
f(x)=2x-3
f(7) so put x = 7
f(7) = 2(7) - 3
f(7) = 11
Now,
f(-2) so put x = -2
f(-2) = -2×7-3
f(-2) = -17
Now,
f(-4) so put x = -4
f(-4)= -4×7-3
f(-4) = -31
Hence,The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.

Step-by-step explanation:
f(x)=2x-3
now,
f(7)=2× 7-3
=14-3
=11
f(-2)='-2×7-3
= -14-3
b= -17
f(-4)= -4×7-3
= -28-3
= -31

0.7 repeated can be written as a fraction .
What are Fractions?
Fractions are defined as a part or portion in a whole. There are two parts for a fraction, numerator which is the upper part and the denominator, which is the lower part.
Fractions are generally written in the form , where p and q are real numbers. Here, the number p is called the numerator and the number q is called the denominator.
Fractions can be simplified as decimals.
We have to find the fraction representing the number 0.7 repeated.
0.7 repeated is actually the number 0.77777.....
The quotient of 5/8 = 0.625
The quotient of 6/7 = 0.857...
The quotient of 7/9 = 0.777.......
The quotient of 7/100 = 0.07
So, the quotient of 7/9 is the required number.
Hence the fraction which on simplification gives 0.7 repeated is 7/9.

The angle will a 35-ft. ladder make the horizontal if it reaches the sample spot is .
Given that,
A 30-ft. ladder makes an angle of 60 degrees with the horizontal.
We have to find,
The angle will a 35ft.ladder make the horizontal if it reaches the sample spot.
According to the question,
A 30-ft. ladder makes an angle of 60 degrees with the horizontal when it reaches a given spot on a wall.
h = 30sin60
Then, the angle will a 35-ft. ladder make the horizontal if it reaches the sample spot.
Hence, The angle will a 35-ft. ladder make the horizontal if it reaches the sample spot is
For more information about Trigonometry click the link given below.
sin60=h/30
h=30sin60
Now we can find the angle that the 35 ft ladder make when it touches the same spot.
sinα=h/35 and using h we found earlier...
sinα=(30sin60)/35
α=arcsin[(30sin60)/35]
α≈47.93 (α≈47º55'42")
