G(x)=x^2-4x+11
Find g(-7)
Answers
Answer:
1) -43 2)-10
Step-by-step explanation:
so for the first one you would enter -9 into all of the x's
g(x)=4x-7
g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)
g(-9)=-43
second one would be the same thing
g(x)=x^2-4x+11
g(-4)=-7^2-4(-7)+11
g(-4)=-10

Please answer this question. The answer is 2.77cm but my teacher wants a two triangle solution.
Answers

Answer:
5.69 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA can remind you of the relationships between angles and sides in a right triangle. Here, the useful ones are ...
Cos = Adjacent/Hypotenuse
Sin = Opposite/Hypotenuse
__
Using the first of these, we can find GD:
cos(52°) = GC/GD
GD = GC/cos(52°)
Using the second of these, we can find GH:
sin(64°) = GH/GD
GH = GD·sin(64°)
Substituting for GD, we find ...
GH = GC·sin(64°)/cos(52°)
GH ≈ (3.9 cm)(0.8988/0.6157)
GH ≈ 5.69 cm
_____
Additional comment
The length 2.77 cm given in your question is the approximate length of DH. That solution is DH = (3.9 cm)·cos(64°)/cos(52°) ≈ 2.7769 cm ≈ 2.78 cm.
Problems of this nature tend to be formulated different ways, so the specific answer will depend on the specific question. Angles and lengths and requested information may vary, even though the picture looks very similar. Read all the words.

Find volumeof right circular cone having base radius 14cm and slant height 14.8cm.
Answers
Answer:
The cone has a volume of approximately 982.5 cubic centimetres.
* That answer sounds off to me, but I'm not sure. You might want to run through the logic yourself and see if you get the same results.
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and base radius. In other words:
[tex]v = \pi r^{2} \frac{h}{3}[/tex]
But before using that, we need to know the value of h, height. What we are instead given is the slant height, or the length from tip to edge.
We can use that slant height along with the base radius to get the cone height, as the three of them are the edges of a right triangle, with slant height being the hypotenuse.
To get the height then we can say
[tex]h = \sqrt{s^{2} - r^{2}}[/tex]
Where h is height, s is slant, and r is radius.
[tex]h = \sqrt{14.8^{2} - 14^{2} }[/tex]
[tex]h = \sqrt{219.04 - 196}[/tex]
[tex]h = \sqrt{23.04}[/tex]
[tex]h = 4.8[/tex]
A very squat cone indeed.
Now we can plug that and the radius into the actual cone equation:
[tex]v = \pi (14cm)^{2} \frac{4.8cm}{3}\\= \pi 196cm^2 * 1.6cm\\\approx 985.2 cm^3[/tex]

A driver drives to school along the same routine Monday through Friday. There is one traffic light on her route . The probability that the light will be red is 65% . What is the probability that she will not have to stop at the light all next week?
Answers
Answer:
0.525%
Step-by-step explanation:
Since we are trying to find the probability of a sequence of events we simply need to multiply the probability of each of these events happening separately from one another. We are told that the probability that the light will be red is 65% that means that the probability that it will be green and that the driver will not need to stop is 35%. This probability remains the same every day of the week. Therefore we need to multiply this probability 5 times, one time for each weekday Monday through Friday, but first we need to turn this percentage into a decimal form by dividing it by 100...
35% / 100 = 0.35
0.35 * 0.35 * 0.35 * 0.35 * 0.35 = 0.00525 ...multiply by 100 to get percentage
0.00525 * 100 = 0.525%
Finally, we can see that the probability that she will not have to stop at the light all next week is 0.525%

Answers
Answer:
IJ is 5.8 ft
Step-by-step explanation:
Here, we want to calculate the length of IJ
to Find IJ, we need the appropriate trigonometric ratio
The trigonometric ratio to use in this case is the one that connects the opposite and the adjacent
from the question, IJ is the opposite
This is the side facing the given angle
HI is the hypotenuse which is the side facing the right-angle
HJ is the third side which is the adjacent
Mathematically;
That is the Tan
Tan 71 = IJ/2
IJ = 2 Tan 71
IJ = 5.8

Three different coins are tossed. What is P(tail, head or tail, head, or tail)
Answers
Answers:
Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]
Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]
Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]
Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]
Step-by-step explanation (Read Carefully):
-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:
-A way to organize this is to have:
H = heads
T = tails
-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
Now, let’s apply some questions:
⇒ Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].
⇒ Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

The local water supply has a leak, it is losing 4 gallons of water every second.
After 15 seconds, the water level is at 1024 gallons. Write an equation to
represent the situation: *
Answers
Answer:
An equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Step-by-step explanation:
Given that the water supply is losing 4 gallons of water every second.
It means the rate of change = 4 gallons per second
Given that after 15 seconds, the water level is at 1024 gallons.So the equation becomes
1024 = 4(15) + b
comparing with the slope-intercept form of the equation of a line
[tex]y = mx+b[/tex]
where m is the slope (rate of change) and b is the y-intercept
so
[tex]1024 = 4(15) + b[/tex]
[tex]1024 = 60 + b[/tex]
[tex]1024 - 60 = b[/tex]
[tex]b = 964[/tex]
So, the value of y-intercept i.e b=964
Thus, the equation will be
[tex]y = mx+b[/tex]
substituting the value rate of change i.e m = 4 and b=964
[tex]y = 4x + 964[/tex]
Therefore, an equation to represent the situation would be:
[tex]y = 4x + 964[/tex]
