The graph shows that the function is equal to y = 2cos(3x) + 1 because in the graph I notice that the table is (0, 3), (60°, -1), and (120°, 3). It shows that a is equal to 2, b is equal to 3, and c is equal to -1, making the function equal to y = 2cos(3x) + 1

a = 2
b = 3
c = 1

Find f' f(x)=sqr root(x+9), a=7 use the definition lim f(x+h)-f(x)/h

Romashka-Z-Leto [24]

f(x)=√(x+9)

f(x+h) =√(x+h+9)

$f'(x) = \lim_{h \to \\0} \frac{\sqrt{x+9+h}-\sqrt{x+9}}{h} = \\ \\ = \lim_{h \to \\0} \frac{(\sqrt{x+9+h}-\sqrt{x+9})*(\sqrt{x+9+h}+\sqrt{x+9})}{h(\sqrt{x+9+h}+\sqrt{x+9})} = \\ \\= \lim_{h \to \\0} \frac{(\sqrt{x+9+h})^{2}-(\sqrt{x+9})^{2}}{h(\sqrt{x+9+h}+\sqrt{x+9})}= \\ \\= \lim_{n \to \\0} \frac{x+9+h-x-9}{h(\sqrt{x+9+h}+\sqrt{x+9})}=\lim_{n \to \\0} \frac{h}{h(\sqrt{x+9+h}+\sqrt{x+9})}=\lim_{n \to \\0} \frac{1}{(\sqrt{x+9+h}+\sqrt{x+9})} = \\ \\= \frac{1}{(\sqrt{x+9+0}+\sqrt{x+9})} =$

$=\frac{1}{(\sqrt{x+9}+\sqrt{x+9})} = \frac{1}{2\sqrt{x+9}}$

$f'(x)= \frac{1}{2\sqrt{x+9}} \\ \\ f'(a)=\frac{1}{2\sqrt{a+9}} \\ \\a=7 \\ \\f'(7)= \frac{1}{2\sqrt{7+9}} = \frac{1}{2*4} =\frac{1}{8} \\ \\f'(7)= \frac{1}{8}$

118° (10x+2)° solve for x and z

Ghella [55]

Answer:

Simplifying

10x + -2 = 118

Reorder the terms:

-2 + 10x = 118

Solving

-2 + 10x = 118

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 10x = 118 + 2

Combine like terms: -2 + 2 = 0

0 + 10x = 118 + 2

10x = 118 + 2

Combine like terms: 118 + 2 = 120

Combine like terms: 118 + 2 = 12010x = 120

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifying

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifyingx = 12

F(x) = x^2 +3x-2 F(a) = ? find F(x) for the given domain.

Delvig [45]

Answer:

a^2 +3a-2

Step-by-step explanation:

Given the expression:

g(x) = x^2 +3x-2

We are to find f(a). To get this, we will simply replace x with a in the expression as shown;

g(a) = a^2 +3a-2

hence the required domain is expressed as g(a) = a^2 +3a-2

Your cousin gave you $0.72 with which to buy a gift. This covered 9/10 of the cost. How much did the present cost?

Helga [31]

Answer:

$0.80

Step-by-step explanation:

percent times the original number equals the part

(%)(start or total cost)= (part of the total cost). you need to know the total cost, so you would fill in the part and the percent. 0.9x=0.72. you use x because you don't know what the total cost is. then you divide both sides by 0.9 to get x by itself and you get that x = 0.8, meaning that the present costs $0.80.

How do i find the quotient of rational expressions???

alisha [4.7K]

First, turn it into a multiplication problem by multiplying by the reciprocal of the divisor. Then, you can cancel common factors in the numerator and denominator to make things easier to work with. Finally, multiply to get your final answer!
