f(x)=3x^2+6x-18 , find f(10)
Answer:
f(10)=342
Step-by-step explanation:
f(10)= 3(10)^2+6(10)-18
complete your exponet first and multiply 6(10)
f(10)=3(100)+60-18
multiply the 3(100)
f(10)=300+60-18
add and subtract all the numbers together
f(10)=342

Problem 1
Answer: DF = 2.68-----------------------------------
Explanation:
The scale factor is DE/AB = 1.34/2 = 0.67
This means DE is 67% of the length of AB
Or you could say that DE = 0.67*AB
This means that
DF = 0.67*AC
DF = 0.67*4
DF = 2.68
Side note: AC and DF are the first and last letters of ABC and DEF respectively. This is why AC and DF correspond together.
===========================================================
Problem 2
Answer: EF = 2.01-----------------------------------
Explanation:
We'll use the same scale factor to find EF
new side = (scale factor)*(old side)
EF = 0.67*BC
EF = 0.67*3
EF = 2.01
Side note: BC and EF are the last two letters of ABC and DEF respectively, so BC corresponds to EF.

Determine the slop of the linear function
Answer:
y = 5x.
Step-by-step explanation:
Read the table from top to bottom. You'll see that each time x increases by 1, y increases by 5. We know immediately that the slope of this line is m = rise/run = 5/1 = 5.
Using the first point (2, 10), we see that y = 10 when x = 2. Fit this info into the slope-intercept form of the equation o a straight line:
y = mx + b becomes 10 = 5(2) + b, or b = 0, and the final equation is y = 5x.
The measure of an angle is 53.8°. What is the measure of its complementary angle?
Step-by-step explanation:
Complementary angles means that the angles should add up to 90°.
let the complementary angle of 53.8° is x°.
So,
53.8° + x° = 90°.
x° = 90°-53.8°
x = 36.2°

Step-by-step explanation:
Because a trangle have 180 degree inside
Answer:
Step-by-step explanation:
second one - for this one you would do 90 +30 = 120
then take this from 180 to get 60 . so if you can see that the shape is an f but that's if you take away the sides with the right angles . the corresponding angle rule (you can see an F shape) means that the angle that i just worked out is the same as angle c so angle c=60
third one - for this one do 70+30 then take this answer away from 180
that angle x
the rule for angle y is the vertically opposite angle rule - angle s that are vertically opposite are the same angle y= angle x - same angle

The graph of F(x) shown below resembles the graph of G(x)=x^3, but it has been changed somewhat. Which of the following could be the equation of F(x)?
Answer && Step-by-step explanation:
We know f(x) transcribes towards -x axis. thus ruling out b and d (remember signs opposite of what they mean on the board, you would think +# =towards x axis and vice versa also note if multiplied by a negative on the outside, flips signs inside)
choosing A.
plug in values of -x to see if you can get ~= to graph so -5 to -1
x: -5, -4, -3, -2, -1
y: -2, -.25, 0, .25, 2
checks out., A is your answer
The equation for f(x) is F(x) = 1/4(x+3)²
Given is a graph, showing the function g(x) = x³, we need to find the equation for the function f(x) in the graph,
We know f(x) transformed towards x-axis.
We see that, there is a left shift of 3 units, so the function will be (x+3)³
Also, the graph is spread out 4 units, so the function can be 1/4(x+3)³
Hence, the equation for f(x) is F(x) = 1/4(x+3)²

Answer:
There is 4/6 as a fration or 4.6
Step-by-step explanation:
Answer:
2:3 is equivalent to 4:6
Step-by-step explanation:
I know that these ratios are equivalent because each side of the ratio 4:6, are divided by the same number, 2, 4 divided by 2 is 2 and 6 divided by 2 is 3 which gives us a equivalent ratio of 2:3

Answer: Soil loss is caused by a variety of factors, including erosion from wind and water, mechanical tilling, logging, agricultural practices, and poor water management. Erosion and sedimentation, the major effects of soil loss, are widespread and can be devastating.
Erosion
Erosion is a natural process on hill slopes. The rate of erosion is determined by several factors, including soil type, rainfall, and length and percent of slope. Generally, human-induced changes in the landscape lead to higher levels of erosion than would occur naturally. While there are many ways to minimize erosion, vegetative cover is the most effective over the long term. Eroding road.When vegetation is removed, the rate of soil erosion is greatly accelerated, often beyond sustainable levels.
Sedimentation
Eroded soil deposited downslope is referred to as sedimentation. When severe rain or wind events occur or soils are disturbed by human
The Sedimentation Control Act of 1973 requires operators to implement short- and long-term mitigation measures to reduce erosion on- and off-site. Forest landowners who wish to harvest trees are exempt from these regulations if they comply with forestry practice guidelines, which include erosion control measures and mitigation. Best management practices (BMPs) are voluntary practices that reduce sources of se

Answer:
maximum: 12at x = 0Step-by-step explanation:
The x-term has even degree so is never negative. The x-term is subtracted from 12, so the maximum value of the function will be found where x=0. That value is 12 -0 = 12.
f(0) = 12 . . . . absolute maximum
Answer:
The function [tex]f(x)=12-6x^4[/tex] has an absolute maximum value of [tex]12[/tex] and this occurs at [tex]x $\ equals 0.[/tex]
Step-by-step explanation:
The maximum value of this function is at 12, because if you rewrite this function:
[tex]f(x)=-6x^4+12[/tex]The +12 is the k-value (the graph of this function is a parabola) of the vertex form of a quadratic. Just a reminder:
Vertex form of a parabola:
[tex]a(x-h)^2+k[/tex]You can see the 12 is the k-value. The k-value of the vertex form is the vertical shift of the parabola, meaning that this parabola is shifted 12 units upwards.
Since the parabola opens down (you can tell by the negative a-value [tex]-6[/tex]), there is a maximum value at the k-value, i.e. the vertical shift.
[tex]f(x)=-6x^4+12[/tex] has an absolute maximum value of [tex]12[/tex].
To find where the maximum value occurs at, the formula:
[tex]-\frac{b}{2a}[/tex]Tells us the x-value of the vertex of the parabola, whose y-value is the maximum value.
Using our rearranged equation, the a, b, and c-values are:
[tex]a=-6[/tex][tex]b=0[/tex][tex]c=12[/tex]Plug in the a and c values into the formula to find the x-value of the maximum point:
[tex]-\frac{b}{2a}[/tex][tex]-\frac{(0)}{2(-6)}=0[/tex]Therefore, the absolute maximum value of 12 occurs at x = 0.
