Answer:
n = - 6
Step-by-step explanation:
Given (x + h) is a factor of a polynomial f(x) then f(- h) = 0
Here
f(x) = x³ + 2x² - 5x + n and (x + 3) is a factor then f(- 3) = 0 , that is
f(- 3) = (- 3)³ + 2(- 3)² - 5(- 3) + n = 0 , so
- 27 + 2(9) + 15 + n = 0
- 27 + 18 + 15 + n = 0
6 + n = 0 ( subtract 6 from both sides )
n = - 6

Answer:The equation that was given in the question is:
[tex] - 8.5 \times - 3.5 \times = - 78[/tex]
Also,the value of x given is 6.5
Therefore, we'll put the value of x back into the equation and this will be:
[tex] - 8.5 \times - 3.5 \times = - 78 \\ - 8.5(6.5) - 3.5(6.5) \\ - 55.25 + - 22.75 \\ = - 78[/tex]
Therefore, the answer is correct

Pamela's age is two times Jiri's age. The sum of their ages is 33. What is Jiri's age?
please please help
Answer:
Let Jiri's age be as 'x'
Therefore, Pamela's would be 2x
Since the addition of both is 72, the equation formed would be..
2x+ x =72
3x =72
x= 72÷3
x = 24 years.
Therefore, Jiri's age is 24 and Pamela's is twice of Jiri ie 48 years.

The path of a large arrow fired from a catapult can be modeled by y= -0.0044x^2+1.68x, where x is the distance the arrow traveled (in yards) and y is the height of the arrow (yards).
Give the height of the castle wall, find the safest distance from the wall to launch an arrow over the wall.
1. the height of the wall is 120 yards
2. the height of the wall is 100 feet.
Answer:
Step-by-step explanation:
Wwe can solve this in either of two ways: Differentiation or graphing.
Differentiation
y= -0.0044x^2+1.68x
y' = -0.0088x + 1.68
y' is an equation that tells us the slope of the line for any point x. We want to know when the arrow begins it's descent. That is the point of maximum height, and the slope of the line through that point will be zero. Set y' = 0 and solve for x:
0 = -0.0088x + 1.68
0.0088x = 1.68
x = 191
The maximum height is when the arrow has travelled 191 feet. Now put 191 feet into the equation to find the maximum height:
y= -0.0044x^2+1.68x
y(191) = feet
The maximum height is 160 feet

Question 11 Objective: Solve for unknown side lengths of right triangles using trigonometric ratios. A right triangle has one angle that measure 27. The adjacent leg measures 29.6 cm and the hypotenuse measures 40 cm. What is the approximate area of the triangle? Round to the nearest tenth. Area of a triangle = 1/2bh а
Answer:
A≈ 268.76 sq cm.
Step-by-step explanation:
sine 27 = opposite side/hypotenuse
sine 27 = x/40
sin 27(40) = x
18.15961999 =x
18.16 = x
A = 1/2(29.6)(18.1596199)
A = 268.7623759
A≈ 268.76 sq cm.

Victoria is four years older than her neighbor the sum of their ages is no more than 14 years enter an inequality that can be used to represent the situation in the box where X represents Victoria’s neighbors age
Answer:
Victoria is 4 years older than her neighbor
Step-by-step explanation:
V = x + 4
x = neighbors age
x + x + 4 < = 14...here is the inequality
2x + 4 < = 14.....this is just a simplified form of the inequality
not sure which one u want to write, because they are both basically the same...one is just simplified a little
2x + 4 < = 14
2x < = 14 - 4
2x < = 10
x < = 10/2
x < = 5.....the oldest age of the neighbor is 5
(Hope this helps can I pls have brainlist (crown☺️)
Answer: 5
Step-by-step explanation:
Let x be the age of Victoria's neighbor.
Victoria's age is 4 years older than her neighbor, so her age can be represented as x + 4.
The sum of their ages is no more than 14 years, which can be written as:
x + (x + 4) ≤ 14
Simplifying the inequality:
2x + 4 ≤ 14
2x ≤ 10
x ≤ 5
Therefore, the inequality that represents this situation is x + (x + 4) ≤ 14, where x is less than or equal to 5.
Gavyn drivers at a speed of 50 miles per hour. How long will it take to drive 225 miles
Answer:
4.5hours - 4h30 min
Step-by-step explanation:
Doing the math: 225 miles : 50 miles per hour = 4.5 hours
Thinking about it: 50 mph means that it takes 1 hour to do 50 miles. in 2 hour he travels 100. double again, it's 4 hours for 200 miles. Then there's 25 left, so half an hour. 4.5 hours or 4h30min

The sale price of a swimming pool after a 18.5% discount is $1189.90. Find the original list price of the pool.
Answer:
1460
Step-by-step explanation:
18.5% of 1460 = 270.1
1460 - 270.1 = 1189.9
$1,000 invested at 8% compounded semiannually after a period of 2 years
Answer:
1160 will be the new amount after 2 years
Step-by-step explanation:
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
Therefore 1160 is the new amount after two years.

2. No
3. No
4. Yes
Step-by-step explanation:
Insert each y value into the equation. If it equals -14, then it is a solution to the equation. The only one of these y values that is a solution is the last one, -2.
8 * (-2) = -16
-16 + 2 = -14
So y = -2 is a solution.
The triangle below is equilateral. Find the length of side xx in simplest radical form with a rational denominator.
Answer:
x= 12 cm
Step-by-step explanation:
Answer:
[tex]x=(4\sqrt{3})/3[/tex]
Step-by-step explanation:
If we know that it is equilateral, we know that all angles are 60 degrees, which makes the top smaller triangle a 30-60-90 triangle. Applying the 30-60-90 triangle theorem, we get x=4/sqrt3. By rationalizing the denominator, we get [tex]x=(4\sqrt{3})/3[/tex]
