50 POINTS!!! I WILL GIVE BRAINLIEST TO WHOEVER SHOWS STEPS! THANK YOU!:)))

taurus [48]

Answer:

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23

The top of two poles of height's 20m and 14m are connected by the wire

Hatshy [7]

Answer:

The correct option is;

10 m

Step-by-step explanation:

The parameters given are;

Height of the first pole = 20 m

Height of the second pole = 14 m

The angle the wire connected to their top makes with the horizontal = 30°

The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.

Let the horizontal distance between the two poles = D

Therefore;

The horizontal length of the wire = D

From trigonometric ratios, we have;

$tan(30 ^{\circ}) = \dfrac{h}{D} = \dfrac{6}{D}$

Which gives;

$D = \dfrac{6}{tan(30 ^{\circ}) } = 10.39 \ m\approx 10 \ m$

The correct option is 10 m.

Use the definition f ′(x) = h0f(x + h) - f(x)h to find the derivative. f(x)=x+2

NNADVOKAT [17]

Answer:

f'(x) = 1

General Formulas and Concepts:

Calculus

Limit Properties: $\lim_{n \to a} c = c$
Definition of a Derivative: $f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = x + 2

Step 2: Find derivative

Substitute: $f'(x)= \lim_{h \to 0} \frac{((x + h) + 2)-(x+2)}{h}$
Distribute: $f'(x)= \lim_{h \to 0} \frac{x + h + 2-x-2}{h}$
Combine like terms: $f'(x)= \lim_{h \to 0} \frac{h}{h}$
Divide: $f'(x)= \lim_{h \to 0} 1$
Evaluate: $f'(x)= 1$
