Answer: 12 only
Step-by-step explanation:
The value of f(0) from the graph of f(x) is (a) 12 only
What are functions?Functions are used to represent graphs, equations, ordered pairs and relations.
To interpret the value of the function, we start by reading the graph.
From the graph, the value of the function when x = 0 is 12
This means that:
[tex]f(0) = 12[/tex]
Hence, the value of f(0) from the graph of f(x) is (a) 12 only

Find the unit rate for 3/4 miles 1/2 hour
Answer:
Step-by-step explanation:1 2 mile in each 1 8 hour is a rate of 4 miles per hour. 1 5 mile in each 1 10 hour is a rate of 2 miles per hour. is correct ,i think??????
The unit rate is 3/2, which means the person is traveling at a rate of 3/2 miles per hour.
How to determine the unit rate for 3/4 miles 1/2 hourTo find the unit rate, divide the distance traveled (in this case, 3/4 miles) by the time taken (in this case, 1/2 hour).
(3/4 miles) ÷ (1/2 hour)
To divide fractions, multiply the numerator of the first fraction by the reciprocal of the second fraction:
(3/4 miles) × (2/1 hour)
Multiplying the numerators and denominators, we get:
(3 × 2) / (4 × 1) = 6/4
Next, simplify the fraction:
6/4 simplifies to 3/2
Therefore, the unit rate is 3/2, which means the person is traveling at a rate of 3/2 miles per hour.

Item 3
The table shows the cost of renting bowling shoes.
Number of Pairs of Shoes Cost
1 $2.50
2 $5.00
3 $7.50
4 $10.00
5 $12.50
What does the rate of change mean in this situation?
The cost increases $10.00 for every additional pair of shoes rented.
The cost increases $5.00 for every additional pair of shoes rented.
The cost increases $2.50 for every additional pair of shoes rented.
The cost increases $7.50 for every additional pair of shoes rented.
Answer:
C) The cost increases $2.50 for every additional pair of shoes rented.
Step-by-step explanation:
Notice a pattern. When you buy a new pair of shoes, the total gets increased by $2.50 depending on how many pairs of shoes you buy. For example, starting with 1 pair of shoes, it costs $2.50, but when you buy another pair, the cost is $2.50+$2.50=2*$2.50=$5.00, and so on...
Therefore, the correct choice is C

Hello! :)
[tex]\large\boxed{\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}}[/tex]
Find the derivative using the quotient rule:
[tex]\frac{f(x)}{g(x)} = \frac{g(x) * f'(x) - f(x) * g'(x)}{(g(x))^{2}}[/tex]
In this instance:
[tex]f(x) = e^{\frac{3}{x} }\\\\g(x) = x^{2}[/tex]
Use the following properties to find the derivative of f(x) and g(x):
[tex]e^{u} = u' * e^{u}\\\\x^{n} = nx^{n-1}[/tex]
Use the quotient rule:
[tex]\frac{x^{2} * (e^{\frac{3}{x}} * (-3x^{-2})) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}[/tex]
Simplify the numerator:
[tex]\frac{(e^{\frac{3}{x}} * (-3)) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}[/tex]
Factor out [tex]e^{\frac{3}{x}}[/tex]

Yo no comprehendo espanol mucho, but I'll try
12y + 15 + y - 36y - 9 = y
Rearrange
12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)
12y - 36y = - 15 + 9
-24y = - 6
Divide both sides by - 24 (Take note of the signs (+) (-))
-24y/-24 = - 6/-24
y= 1/4

What is the length of side AC
Answer:
7 Units.
Step-by-step explanation:
First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD=3 and DC=12, what is the length of BD?
Answer:
The answers is 8.06on DeltaMath
Step-by-step explanation:
The length of BD which is the altitude of the right angle triangle will be 6 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.
A right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 3 and DC = 12.
Then the equation is given as,
BD² = AD x DC
BD² = 3 x 12
BD² = 36
BD = 6
The length of BD which is the altitude of the right angle triangle will be 6 units.
