Hi please help me it’s so important!!
question is attached
f ( x ) = x² + 144
=> x² + 144 = 0
=> ( x + 12 ) ( x - 12 ) = 0
=> x + 12 = 0 and x - 12 = 0
=> x = -12 and x = 12
So,the zeroes of f are -12 and 12 .

Answer:
-23, 5
Step-by-step explanation:
JK = 14 and K = -9
J could be on the left or the right of -9
Add 14 to -9
14+-9 = 5
So J could be at 5
Subtract 14 from -9
-14-9 = -23

How do I solve this problem?
Answer:
KN = 72
Step-by-step explanation:
ΔKPL and ΔKNM are similar.
∠KLP = ∠KMN (Because PL and NM are parrallel)
∠KPL = ∠KNM (Because PL and NM are parrallel)
∠NKM = ∠PKL (Same angle, Common)
Now, Both the trianlges are similar just there is a size difference.
First we need to find scale factor, therefore:
[tex]\frac{KL}{LM}[/tex] = [tex]\frac{11}{55}[/tex] = [tex]\frac{1}{5}[/tex]
Now we know the scale factor is [tex]\frac{1}{5}[/tex] therefore:
[tex]\frac{KP}{PN}[/tex] = [tex]\frac{PK}{60}[/tex]
To find PK we times 60 by [tex]\frac{1}{5}[/tex] therefore:
Answer is 12
Now KN is PK+ PN threfore:
KN is 72

The diameter of a cylindrical construction pipe is 4ft If the pipe is 17ft long, what is its volume? Use the value 3.14 for /pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
213.52 cubic ft
Step-by-step explanation:
Diameter of pipe = 4ft
radius for circle is half of diameter
thus radius of pipe = 1/2 of 4ft = 2 ft
length of pipe = 17 feet
volume of cylinder is given by [tex]\pi r^2l[/tex]
where r is the radius and l is the length of cylinder
.
thus volume of pipe is calculated below using above values
[tex]volume \ of \ pipe = \pi r^2l\\volume \ of \ pipe = \3.14* 2^2*17 \\volume \ of \ pipe = 213.52[/tex]
volume of pipe is 213.52 cubic ft.

prove the trig identity: tan^2 x cos^2 x = (sec^2 x -1)(1-sin^4 x)/1+sin^2 x
Answer:
See steps below
Step-by-step explanation:
We need to work with each side of the equation at a time:
Left hand side:
Write all factors using the basic trig functions "sin" and "cos" exclusively:
[tex]tan^2(x)\,cos^2(x)=\frac{sin^2(x)}{cos^2(x)} cos^2(x)=sin^2(x)[/tex]
now, let's work on the right side, having in mind the following identities:
a) [tex]sec^2(x)-1=tan^2(x)=\frac{sin^2(x)}{cos^2(x)}[/tex]
b) [tex]1-sin^4(x) =(1-sin^2(x))\,(1+sin^2(x))[/tex]
c) [tex]1-sin^2(x)=cos^2(x)[/tex]
Then replacing we get:
[tex]\frac{(sec^2(x)-1)\,(1-sin^4(x))}{1+sin^2(x)} =\frac{sin^2(x)(1+sin^2(x))(1-sin^2(x))}{cos^2(x)(1+sin^2(x)))} =\frac{sin^2(x)(1+sin^2(x))\,cos^2(x)}{cos^2(x)(1+sin^2(x)))}=sin^2(x)[/tex]
Therefore, we have proved that the two expressions are equal.

In right triangle DEF, mE = 90, DE = 8, EF = 15, and FD = 17. What is the value of tan F?
Answer:
The value of tan F = 8/15 or 0.533333
Step-by-step explanation:
To find the value of tan F, we will follow the steps below;
We will use trigonometric ratio. that is;
SOH CAH TOA
sin Ф = opposite / hypotenuse
cosФ = adjacent/hypotenuse
tan Ф = opposite/adjacent
if Ф = F
then opposite = DE = 8
adjacent = EF = 15
web can now proceed to insert the values into the formula
tan F = opposite/ adjacent
tan F = 8/15
tan F = 0.5333
tanF = oppos

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a blue marble is 1/9 There are 45 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.
Answer:
40
Step-by-step explanation:
Since the probability to choose a blue marble is 1/9, there must be 5 blue marbles since 45 * 1/9 = 5
Subtract 5 from 45 to get 40, since the rest of the marbles are red.

Answer:
rectangle 32
triangle 16
Step-by-step explanation:
The area of the rectangle is
A = bh
A = 8*4 = 32
The area of the triangle is 1/2 of the area of the rectangle
A =1/2 bh = 1/2 *32 = 16
Answer:
triangle = 16
rectangle = 32
It's the last option
Step-by-step explanation:
A for rectangle = b * h
= 8 * 4
= 32
