17 : i 12x^2(4x−3) ,

ii : 5x(x−3y) ,

iii: 5xy^2z(3x^2−5z^2)

18) since the two polynomial are equal then :

2x^3+ax^2+3x-5 = x^3+x^2-2x+a  same remainder x-2 then x=2

2(2)^3+a(2)^2+3(2)-5=(2)^3+(2)^2-2(2)+a     solve for a

-3a=9

a=-3

18 ) x^3+y^3 -125+15xy

       x^3+y^3-(5)^3-3(x)(y)(-5)   then factorize x^3+y^3

       (x+y)(x^2-xy+y^2)- (5)(5)^2-3(x)(y)(-5)   common factor x+y-5

        (x+y-5)(x^2-xy+y^2-5^2-3xy         given x+y=5

          5-5( x^2-xy+y^2-25-3xy) = 0

the value of the expression equal to zero

Which graph represents the function f(x) = 4|x|? (please answer honestly I'm on a timed test rn)

Answers

Answer:

The graph that corresponds to the function is B.

Step-by-step explanation:

We want to see which one of the given graphs represents the function f(x) = 4*|x|

The correct option is the second graph.

How to find the correct graph?

Here we want to find the graph of the absolute value function:

f(x) = 4*|x|

To get it, we can evaluate the function in some values of x and then see which graph contains these points.

for example for x = 1 and x = -1 we have:

f(1) = 4*|1| = 4

f(-1) = 4*|-1| = 4

Then we need to see which graph contains the points (1, 4) and (-1, 4)

We can see that the only graph that contains these points is the second one, so the correct option is the second graph.

A bowl contains 5 red balls and 5 white balls. Dorothy selects balls at random without looking at them. How many balls must she select to be sure she has at least two red balls?

Answers

Answer:

7

Step-by-step explanation:

To find the answer, consult the worst case. The worst thing that can happen is Dorothy selects the 5 white balls first. Now, only red balls remain. Since Dorothy can only select red balls, the first 2 balls she will pick will be red. 5+2=7. Dorothy must select 7 balls to be sure she has at least 2 red balls.

The number of balls that Dorothy must select to be sure she has at least two red balls is 6.

How many balls must she select to be sure she has at least two red balls?

To be sure Dorothy has at least two red balls, we need to consider the worst-case scenario where she selects all the white balls before selecting any red balls.

Since there are 5 red balls and 5 white balls, the probability of selecting a red ball on the first draw is 5/10 or 1/2. If Dorothy selects a white ball on the first draw, the probability of selecting a red ball on the second draw is 5/9 since there will be 5 red balls and 9 balls in total remaining in the bowl.

In the worst-case scenario, Dorothy selects all 5 white balls first, so she needs to draw at least 6 balls to be sure she has at least two red balls. This is because on the sixth draw, there will be 5 red balls and 4 white balls left in the bowl, ensuring that she gets at least two red balls.

Therefore, the number of balls Dorothy must select is at least 6 balls to be sure she has at least two red balls.

Y
Value: 10
x is equal to
degrees.
Angle Y measures

Answers

Answer:

x is equal to 16 degrees

Angle measures 62 degrees

Step-by-step explanation:

From Law of Sines:

XW/sin(∠Y) = WY/sin(∠X)

From the picture

XW = 8

WY = 8

∠X = 62°

Replacing into the equation:

8/sin(∠Y) = 8/sin(62°)

∠Y = 62°

Angle Y is also equal to:

∠Y = 4x - 2

62 = 4x - 2

62 + 2 = 4x

64/4 = x

16° = x

y = [?]x +
Hint: Use the Point-Slope Form: y - y1 = m(x - X1)
Then write the equation in slope-intercept form.

Answers

Answer:

y=4x-31

Step-by-step explanation:

Ignore the hint. Point slope form makes everything so much harder than it has to be.

Parallel lines always have the same slope, in this case 4.

So our equation is now: y = 4x + b

Let's solve for b by plugging in (5, -11), as it's the only point we know is on the parallel line.

-11 = 4(5) + b

-11-20 = b

b = -31

So plug in b: y = 4x - 31

--------------------

Also rate and tell me if I'm correct :)

Answer:

y = -4x + 15.

Step-by-step explanation:

To find the equation of a line perpendicular to y = -2 and passing through the point (4, -1), we can use the point-slope form of a linear equation.

The given line y = -2 has a constant slope of 0 since there is no variable term involving x. A line perpendicular to it will have an undefined slope.

Using the point-slope form, we have:

y - y₁ = m(x - x₁),

where (x₁, y₁) represents the coordinates of the given point (4, -1), and m represents the slope.

Since the slope is undefined, the equation becomes:

y - (-1) = undefined(x - 4).

Simplifying:

y + 1 = undefined(x - 4).

Now, we can write the equation in slope-intercept form by substituting the slope as -4 (the negative reciprocal of 0):

y + 1 = -4(x - 4).

Expanding the right side:

y + 1 = -4x + 16.

To isolate y, we can subtract 1 from both sides:

y = -4x + 16 - 1.

Combining the constants:

y = -4x + 15.

Therefore, the equation of the perpendicular line is:

y = -4x + 15.

Find the area of the arrow above.

Answers

Answer:

610 cm²

Step-by-step explanation:

This is an irregular figure. We can split it up by the triangle and the rectangle on the bottom.

To find the area of the triangle, we must determine the base length. As we can see, the bottom of the arrow has the measure 15 cm, and you can see that the missing section in the base of the triangle is the same measure. Now we find the measure of the base by adding 15 + 8 + 8, which equals 31 cm.

Now we multiply and divide by 2 to find the area of the triangle:

20*31 * 1/2

= 310 cm²

Now, we find the area of the rectangle. We can see that its dimensions are 15 by 20. We can plug these values into the rectangle formula:

A = 15*20

A = 300 cm²

Now we add these values to find the total area:

310 cm² + 300 cm²

= 610 cm²

Explanation:

1. 2/12+3/12 = 5/12<6/12
2. 4/12+3/12+2/12= 9/12>6/12
3. 3/12+1/12+1/12+4/12=9/12>6/12
Answer:

• 2/12 + 3/12 < 6/12
• 4/12 + 3/12 + 2/12 > 6/12
• 3/12 + 1/12 + 1/12 + 4/12 > 6/12

Explanation:

• Question One

Add the fractions together

2/12 + 3/12 = 5/12

Determine which fraction is greater than, less than, or equal to the other

5/12 ? 6/12
5/12 < 6/12

Therefore, 2/12 + 3/12 is less than 6/12.

• Question Two

Add the fractions together

4/12 + 3/12 + 2/12 = 9/12


Determine which fraction is greater than, less than, or equal to the other

9/12 ? 6/12
9/12 > 6/12

Therefore, 4/12 + 3/12 + 2/12 is greater than 6/12.

• Question Three

Add the fractions together

3/12 + 1/12 + 1/12 + 4/12 = 9/12

Determine which fraction is greater than, less than, or equal to the other

9/12 ? 6/12
9/12 > 6/12

Therefore, 3/12 + 1/12 + 1/12 + 4/12 is greater than 6/12.

If the volume of the planter is 2,560 cubic inches,how tall is the planter

Answers

Answer:

Height of Planter = H = 20 in²

Step-by-step explanation:

As the planter is not given in the question, the question is incomplete.

First, lets complete the question by attaching the diagram related to this question.

(SEE THE ATTACHMENT)

Lets consider the right angled triangle that is formed at the top of the planter, as shown in the diagram attached.

The right angled triangle has a width of 16 inches and a heights of 16 inches as well.

We know that the Area of a triangle can be calculated by following formula:

[tex]A=\frac{1}{2}\cdot(width)\cdot(height)[/tex]

Substitute the values to find Area:

[tex]Area = \frac{1}{2}\cdot16\cdot16\\Area = 128 in^2[/tex]

We also know that the Volume of a triangular prism is given by:

[tex]Volume=(Area)\cdot(Height)[/tex]

Where

Area = Area of the face = 128 in²

Height = Height of the planter = H

Volume = 2560 in³

Substitute the values and solve for H:

[tex]2560=128\cdot{H}\\H=\frac{2560}{128}\\H=20in^2[/tex]

Answers

Answer:

[tex]T_n = \left \{ {{T_1=2} \atop {T_n =-5T_{n-1}}} n>1 \right.[/tex]

Step-by-step explanation:

Given

Geometric sequence: 2, -10, 50, -250

Required

Recursive formula of the sequence

We start by naming each sequence

[tex]T_1 = 2\\T_2 = -10\\T_3 = 50\\T_4 = -250[/tex]

Represent each term in relation to the previous term (except T1)

[tex]T_1 = 2\\T_2 =2 * -5\\T_3 = -10 * -5\\T_4 = 50 * -5[/tex]

Recall that

[tex]T_1 = 2\\T_2 = -10\\T_3 = 50\\T_4 = -250[/tex]

So, at this point; we have to make substitutions

[tex]T_1 = 2\\T_2 =T_1 * -5\\T_3 = T_2 * -5\\T_4 = T_3 * -5[/tex]

Subtract 1 from each term on the right hand side

[tex]T_1 = 2\\T_2 =T_{2-1} * -5\\T_3 = T_{3-1} * -5\\T_4 = T_{4-1} * -5[/tex]

Replace each term greater than 1 by n

[tex]T_1 = 2\\T_n =T_{n-1} * -5\\T_n = T_{n-1} * -5\\T_n = T_{n-1} * -5[/tex]

Remove repetition

[tex]T_1 = 2\\T_n =T_{n-1} * -5[/tex]

[tex]T_1 = 2\\T_n =-5T_{n-1}[/tex]

Hence, the recursive formula is

[tex]T_n = \left \{ {{T_1=2} \atop {T_n =-5T_{n-1}}} n>1 \right.[/tex]
