Question is in the photo.
Answer:
is there anymore info in it
Step-by-step explanation:
Step-by-step explanation:
We are finding a polynomial of degree 3.
Since 4 and 5i are the zeroes of the polynomial,
the conjugate -5i must also be such a zero.
=> f(x) = a(x - 4)(x - 5i)(x + 5i)
=> f(x) = a(x - 4)(x² - 25i²)
=> f(x) = a(x - 4)(x² + 25)
When x = 1, f(1) = -234.
=> a(1 - 4)(1² + 25) = -234
=> a(-3)(-26) = -234
=> -78a = -234
=> a = 3
Hence,
f(x) = 3(x - 4)(x² + 25) = 3x³ - 12x² + 75x - 300.

Find the missing angle. Find X
Answer:
I don’t know 160.
Step-by-step explanation:
20 plus 160 equals 180.
The correct answer is 20° since x and 20° are vertically opposite angles.
In other words, the value of x is equal to 20°.
Vertically opposite angles are formed by the intersection of two lines. They are opposite each other and have equal measures. When two lines intersect, the vertically opposite angles are formed on the opposite sides of the intersection point. These angles are also known as vertical angles or opposite angles. The property of vertical angles states that their measures are equal. This means that if one angle measures x degrees, the other vertical angle will also measure x degrees. Vertically opposite angles are important in geometry and are often used to prove theorems and solve geometric problems.
Therefore, the correct answer is 20° since x and 20° are vertically opposite angles.In other words, the value of x is equal to 20°.

[tex]\frac{x+9}{x+3}[/tex] , x ≠ - 3 ;
Step-by-step explanation:
f(x) = x³ + 9x² - 25x - 225 = (x + 9)(x + 5)(x - 5)

Given the condition that you know a student has purchased at least one of the items. What is the probability as a percentage that they purchased only one of the items?
Step-by-step explanation:
This is a case of conditional probability, in which we have to find the probability of ocurance of event E when when event F has already ocured.
To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1.
That is, P(at least one) = 1 – P(none)

Samantha has the equation x^3+2x^2+x=x^3-x. explain how she can find the solution of the equation then solve the equation.
Answer:
x =+-1
Step-by-step explanation:
x^3+2x^2+x=x^3-x
(x^3-2x^2)-(x-2)=x(x^2-1)
x^2(x-2)-(x-2)=x(x^2-1)
(X^2-1)(x-2)=x(x^2-1)
(x+1)(x-1)(x-2)=x(x-1)(x+1)
(x+1)(x-1) ((x-2)-x)=0

Sally eats lunch at a restaurant and her bill is $12. She would like to leave a 15% tip for the waiter.
How much money should she leave?
Answer:
$ 13.80
Step-by-step explanation:
Answer:
Hope this helps!
Step-by-step explanation:
Answer -Full amonut - $13.80. Tip amount - $1.80
First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $12 meal cost is. This is always done by multiplying 0.15 by $12.00, or
0.15 x $12.00=$1.80.
So, the amount of tip you are going to leave is $1.80. full amount - 13.80
What is the surface area of the composite solid? A rectangular prism has a length of 15 meters, width of 10 meters, and height of 25 meters. A triangular prism has a triangular base with a base of 6 meters and height of 8 meters. The prism has a height of 15 meters. 1,508 m2 1,658 m2 1,808 m2 1,958 m2
Answer:
Surface area of rectangular prism = 1550m²
Surface area of triangular prism = 498m²
Step-by-step explanation:
The surface area of a rectangular prism is given by the formula
A= 2(wl+hl+hw)
Where A = surface area
w= width
l= length
h=height
Given that the rectangular prism has a length of 15 meters, width of 10 meters, and height of 25 meters.
A= 2(10×15+25×15+25×10)
A=2(150+375+250)
A=2(775)
A=1550 square meters
Surface area of triangular prism = base of triangle x height of triangle + (length of rectangle x width of rectangle) x 3
Since we are not given length and width of the triangular prism, we could assume the triangular prism has same length and width with the rectangular prism given that it is a composite shape(more than one solid in one)
Given triangular base with a base of 6 meters and height of 8 meters.
Surface area of triangular prism= 6×8+(10×15)×3
=48+150×3
=48+450
= 498 square meters
Surface area of a solid is the 2 dimensional space its surface covers. The surface area of the considered composite solid is given by: Option B: 1658 sq. meters
How to find the surface area of a composite figure?Composite figure is figure made by composing two or more figure. The composite figure may leave a surface common as not a surface of the resultant composite figure due to it being the joining area of two figures, thus, not remaining a surface.
Thus, its surface area would sum of their surface areas - areas of those regions which are not surface anymore.
For the given case, the prisms given are having surface areas as:
Composite figure's surface area = Surface area of its composing figures - any overlapping areas
Surface area of rectangular prism = [tex]2(L.W + W.H + H.L) = 2(15 \times 10 + 10 \times 25 + 25 \times 15) = 1550[/tex] sq. meters.
Surface area of triangular prism = area of its three rectangular faces + area of its base triangles.
For the triangle ABI, Pythagoras theorem is proved to be true with angle I (internally) being right angled triangle. (As we have [tex]10^2 = 8^2 + 6^2[/tex] )
That means the area of those triangles would be base times height times half, which comes as [tex]8 \times 6 \time 1/2 = 24[/tex] sq. units.
The three faces have area as= [tex]15 \times 10 + 15 \times 6 + 15 \times 8 = 15(24) = 360[/tex] sq. meters.
The two triangle faces have area = twice of 24 = 48. surface area of triangular prism = 48 + 360 = 408Sum of area of triangular prism and rectangular prism is 1550 + 408 = 1958 sq. meters
Common area is 10 times 15, its twice is 300, so surface area of the composite figure is 1958 - 300 = 1658 sq. metersThus, the surface area of the considered composite solid is given by: Option B: 1658 sq. meters
