Answer:
(x + 1)(x + 2)(2x + 1)(x - 3).
Step-by-step explanation:
From the leading and last coefficients, 2 and -6 the values +/- 1, +/-2 , +/- 3 could be roots of this equation ( well, up to 4 of them).
Try x = 1:
f(1) = 2(1)^4 + 1^3 - 14(1)^2 - 19(1) - 6 = -36 so its not 1.
f(-1) = 2 - 1 - 14 + 19 - 6 = 0 do x = -1 is a root.
Therefore (x + 1) is a factor (By the factor theorem)
Try x = 2:
f(2) = 32 + 8 -56 - 38 - 6 = -6o so x =2 not a root.
f(-2) = 32 - 8 - 56 + 38 - 6 = 0 so x = -2 is a root and (x + 2) is a factor.
(x + 1)(x + 2) = x^2 + 3x + 2.
Long division:
2x^2 - 5x - 3 <-----------Quotient
--------------------------------------------
x^2 + 3x + 2 ) 2x^4 + x^3 -14x^2 - 19x - 6
2x^4 + 6x^3 + 4x^2
-5x^3 - 18x^2 - 19x
-5x^3 - 15x^2 - 10x
-3x^2 - 9x - 6
-3x^2 - 9x - 6
.......................
2x^2 - 5x - 3 = (2x + 1)(x - 3)
So Finally, the factors are (x + 1)(x + 2)(2x + 1)(x - 3).

evaluate tan-1 (1.6) giving your answer to the nearest degree
Answer:
58degrees
Step-by-step explanation:
Given
tan^-1(1.6)
= tan^-1(16/10)
= tan^-1(8/5)
= 57.99 degrees
Hence the value of tan^-1(1.6) to the nearest degrees is 58degrees

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200
= 50 times

Whats the area of the rectangle?
Length: 2 1/7
width: 3 1/3
I dont need an explanation just the simplified answer
Answer:
The area of rectangle is "31 units²".
Step-by-step explanation:
The given values are:
Length of rectangle,
= [tex]\frac{21}{7}[/tex]
Width of rectangle,
= [tex]\frac{31}{3}[/tex]
As we know,
The area of rectangle is:
= [tex]Length\times width[/tex]
On substituting the values, we get
= [tex]\frac{21}{7}\times \frac{31}{3}[/tex]
= [tex]\frac{217}{7}[/tex]
= [tex]31 \ units^2[/tex]

Evaluate the expression below when n = 2.4. If needed, answer as a fraction or a decimal.
12n−8
Answer:
20.8
Step-by-step explanation:
Plug in 2.4 as n in the expression, and simplify:
12n - 8
12(2.4) - 8
28.8 - 8
= 20.8
So, the answer is 20.8

Since its a 45-45-90 triangle then the 2 legs are going to be the same.
Answer:
90°
Step-by-step explanation:
Always remember that the sum of all angles is 180°.
So there are two 45° angles, so just add them up and you get 90
So if you subtract 90 from 180, you get 90, and that's your answer

Write the decimal as a percent
Answer:
3/5
Step-by-step explanation:
Answer:
66%
Step-by-step explanation:
0.6 repeating is 66%.
From decimal to percent:
To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.
From decimal to fraction to percent:
I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.

The shape of a lateral face of a pyramid is always an isosceles triangle?
Answer:
No.
Step-by-step explanation:
Because the lateral faces of a regular pyramid are congruent isosceles triangles. The altitude of any of these triangles is the slant height of the regular pyramid.
The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?

HELP ME PLZ!!! This is too hard
Answer:
The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].
Step-by-step explanation:
Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:
[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]
[tex]2\cdot \tan \theta = 3[/tex]
[tex]\tan \theta = \frac{3}{2}[/tex]
[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]
The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:
[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

Step-by-step explanation:
A company sells fruit smoothies in two sizes: 6 ounces and 20 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 20-ounce bottle contain?
And can yall put an explanation please
Answer:
320 milligrams of sodium
Step-by-step explanation:
Create a proportion where x is the milligrams of sodium a 20 ounce bottle has:
[tex]\frac{96}{6}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x
1920 = 6x
320 = x
So, a 20 ounce bottle will have 320 milligrams of sodium
The function h(n) = 8 - 3n represents the value of the nth term in a sequence.
What is the product of the 2nd and 5th terms of the sequence?
Answer:
aaaa
Step-by-step explanation:
Answer:
h(2) = 2
h(5) = -7
Step-by-step explanation:
h(n)=8-3n
h(1)=8-3(1) = 5
h(2)=8-3(2) = 2
h(5) = 8-3(5) = 8-15 = -7

Answer:
The area of shaded figure is 30 sq yards .
Step-by-step explanation:
In the graph the figure is consist of :
Many grid square and each square grid is equals one square yards . Two shapes which are parallelogram and triangle .To calculate the area of shaded figure we need to find the area of triangle and parallelogram and combine them to get the area of shaded figure.
Finding the area of triangle:-
Area of triangle = ½ × Base × Height
substitute the values and solve;Area of triangle = ½ × 5 × 4
Area of triangle = ½ × 20 yard²
Hence, the area of triangle is 10 sq yards.
Finding the area of parallelogram :
Here, to calculate the area subtract the area of two small circle from the area of rectangle .
Area of parallelogram = l × b - 2 (( b × h )½)
Substitute the values we get,Area of parallelogram = 4 × 8 - 2 ( 3 × 4 × ½)
Solve it ;Area of parallelogram = 32 - 12.
Substitute 12 from 32 .Area of parallelogram = 20 sq yards.
Hence, Area of parallelogram = 20 sq yards.
Finding the area of shaded figure.Area of figure = Area of parallelogram + Area of triangle.
Area of figure = 20 sq yards + 10 sq yards.
Add 20 sq yards and 30 sq yards.Area of figure = 30 sq yards .
Hence,
The area of shaded figure is 30 sq yards .
