Step-by-step explanation:
Use this polynomial.
[tex] - x {}^{4} +9x {}^{3 } + 13 {x}^{2} - 45x - 50[/tex]
A degree 4 means our leading coefficient looks like.
[tex] {x}^{4} [/tex]
Since our degree is 4, our turning points would be 3.
Since we have three roots, we need two single roots and a double root.
A negative leading coefficient would have a negative sign in front of it.

A 12 feet tall street light is making an 18 feet shadow at the same time in nearby building is making a 72 feet shadow
Answer: 48 ft
Step-by-step explanation:
Given
Height of street light h=12 ft
length of shadow x=18 ft
Shadow length of building x'=72 ft
suppose the height of the building is y
from the figure, we can write
[tex]\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft[/tex]
Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)
Answer:
Step-by-step explanation:
24n + 32w = (3n + w)
We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.
Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that
24n + 32w = 8(3n + 4w)

If m∠3 is 124° and m∠4 = 8x + 40, what is the value of x?
Answer:
10.5
Step-by-step explanation:
M«3 =M«4
124°=8x+40
124°-40=8x+40-40
84=8x
84/8=8x/8

2/3 - 3/2y + 1/3y + 4 = 0
Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Answer:
y = 4
Step-by-step explanation:
Please use parentheses for clarity, remembering what big differences they make in expression values.
I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0" actually means
2/3 - (3/2)y + (1/3)y + 4 = 0
The LCD here is 6, which is the product of the denominators 2 and 3.
Then your "2/3 - 3/2y + 1/3y + 4 = 0" becomes:
4 - 9y + 2y + 24 = 0, which simplifies to:
28 - 7y = 0. Solving this, we get y = 4

Answer:
375.2887 ft is the answer
Answer:
375.3 ft
Step-by-step explanation:
What we need to do first is divide 175 by the sine of 25°.
175/sin(25°)
175/0.422618
175/1 * 500000/211309
25/1 * 500000/30187
12500000/30187
414.085534 = length of hypotenuse.
Now, find the square root of the difference between c² & a².
b = √414.09² - 175²
b = √171470.528 - 30625
b = √140845.528
b = 375.293922
b ≈ 375.3

Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%

What is the volume of the figure?
Answer:
volume of a cone = [tex]\pi[/tex] [tex]r^{2}[/tex] h/3
[tex]\pi[/tex] = 22/7 or 3.14
r (radius) = 8 ft
h (height) = 16 ft
∴ volume = 22/7 * 8 * 8 * 16/3
= 3.14 * 64 * 16/3
= 1072.76190476 [tex]ft^{3}[/tex]
hope this answer helps you.....
please mark as brainliest ..... thank you....
Answer:
1072 ft³
Step-by-step explanation:
Formula we use,
→ V = πr²(h/3)
Now the volume of cone is,
→ πr²(h/3)
→ 3.14 × (8)² × (16/3)
→ 3.14 × 64 × 5.333
→ 200.96 × 5.333
→ 1072.33
→ ≈ 1072 ft³
Hence, volume is 1072 ft³.

y = 3x + 3
y = x − 1
Answer:
Step-by-step explanation:
Well you have to solve for X to find Y simplified.
Since both equations equal Y you can plug them together
3x+3=x-1
-x -x
2x+3=-1
-3 -3
2x=-4
Divide -4 by 2 and you get X = -2 then plug X into both equations and boom
y= -3

A toy company has 6 different heights of its best-selling action figure, labeled versions 1 through 6. Each version is modeled from clay molding of the action figure. Version 1 is 125% taller than the clay molding of the action figure. The heights of action figure versions 2 through 6 are each 125% taller than the previous version of the action figure. The clay molding of the action figure is 4 inches tall. Which function can be used to find the height in inches of each version of action figure, where 1 ≤ v ≤ 6?
h(v) = 1.25(v+ 4)
h(v) = 4(1.25)v
h(v) = 1.25(4)v
h(v) = 4(v + 1.25)

Mount McKinley, in Alaska, is about 3.848 miles high. If a mountain climber can climb 0.25 miles per day, about how long to the nearest day, would it take to climb Mount McKinley?
Answer:
About 16 days.
Step-by-step explanation:
The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim.
They opened a bag of candy and recorded the number of candies of each color. The results are shown in the following table-
Red Green Blue Yellow Orange
17 24 20 25 14
The average of the all the values is 20.
Now, according to the manufacturer, bags should contain an equal number of each color. Thus, the expected value for the bag of candy are,
Red Green Blue Yellow Orange
20 20 20 20 20
Form, the above formula the color which has less values of observed, and more value of expected, contributes most to the chi-square test statistic.
Here, the orange color has the less value of observed frequency. Therefore, the color which contributes most to the chi-square test statistic for the bag of candy is orange color.
