Step-by-step explanation:
Q6
answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.
Q7
answer C, as this curve is the complete opposite of the curve in Q6.
it is the regular parabolic curve but down. that means -x².
but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.
Q8
answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.
and between A and B we need to remember, that a negative exponent means 1/...
in case of B 1/(2^x).
and that would mean for large positive x we would get very small values for y.
but we see the opposite. for large x we also get large y.
so, it is 2^x (answer A).

A group of engineers developed a new design for a steel cable. They need to estimate the amount of weight the cable can hold. The weight limit will be reported on cable packaging. The engineers take a random sample of 44 cables and apply weights to each of them until they break. The 44 cables have a mean breaking weight of 778.1 lb. The standard deviation of the breaking weight for the sample is 15.5 lb.
Find the 99% confidence interval to estimate the mean breaking weight for this type cable.

4(9x+6)=36x-7 And the solution is x=
Answers
Answer:
no solution
Step-by-step explanation:
4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4
36x + 16 = 36x - 7 ( subtract 16 from both sides )
36x = 36x - 23 ( subtract 36x from both sides )
0 = - 23 ← False statement
This indicates the equation has no solution

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary.
(Please show your work)
Answers
Answer:
12
Step-by-step explanation:
Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.
We know that
a²+b²=c²
Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).
We want to find x, which in this case is c. So,
to solve for c, we get
c=[tex]\sqrt{a^2+b^2 }[/tex]
So, after plugging in the values, we get
[tex]c=\sqrt{10.6^2+6.1^2}[/tex]
[tex]c=12.23\\\\=12 (rounded)[/tex]

Answer:
y = -2/3x - 2
Step-by-step explanation:
Picking two points on the line: (0,-2) & (-3,0)
Using the slope formula:
[tex]\frac{x2-x1}{y2-y1}[/tex]
= (0-(-2))/(-3-0)
= 2/-3
= -2/3
y = -2/3x + c
Subsituting (0,-2) into 'y = -2/3x+c':
-2 = 0 + c
c= -2
Hence,
y = -2/3x -2
