Write a quadratic polynomial, sum and product of whose
zeroes are -4 and -21 respectively.

Answers

Answer 1

Answer:

x^2 -4x -21

Step-by-step explanation:

Here, we want to write a quadratic polynomial

We have the sum as -4

Let us have x as the variable

so the sum of the variables is -4x

while the product is -21 x^2

Two factors of 21 that can work here is -7x and 3x

So we have

x^2 - 7x + 3x -21

= x^2 -4x -21

Determine whether a triangle with the given vertices is a scalene, isosceles, or equilateral triangle. Check all that apply.

Answers

9514 1404 393

Answer:

  (a) isosceles

  (b), (c) scalene

Step-by-step explanation:

The lengths of the sides can be found from the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.

We find triangle (a) has two sides the same length, so it is isosceles.

The other two triangles have three different side lengths, so they are scalene.

It is impossible to specify an equilateral triangle using rational coordinates.

A) 38
B) 48
C) 192
D) 202​

Answers

Answer:

D

Step-by-step explanation:

if x= number of hours replace the x by 9

so you have 5×(1.50)^9+10=

5×(192.21)+10 = 202.21 so 202 will be nearest whole number

D) 202

Steps:

Formula 5*(1.50)^x + 10

1. Plug in 9 for x
5*(1.50)^9 +10

2. Solve exponents (38.443359375) and round to nearest hundredth
5*38.44+10

3. Multiply
192.2 +10

4. Add

2.5 minutes it took to pass 12.5

Answer:

2.5 min

Step-by-step explanation:

We can start with the fact that [tex]d = st[/tex], where d is the distance traveled at a speed of s for some amount of time t. If we want to solve for t, we can divide both sides of the equation by s to get the form [tex]t=d/s[/tex]. Plugging in the values of d = 12.5 m and s = 5 m/min gives us [tex]t=12.5/5=2.5[/tex] min.

The volume of a cereal box is 264 in3 . If it has a width equal to 3 inches and length of 8 inches, what is the height?

Answers

Answer:

11 inches

Step-by-step explanation:

Volume of a box is:

[tex]l * w * h[/tex]

[tex]8 * 3 * h = 264\\\\24*h=264\\\\\frac{24*h=264}{24} \\\\\boxed{h=11}[/tex]

The height is 11 inches.

Hope this helps.

Volume of the box = LWH.

Let V = 264

264 = (8)(3)(H)

264 = 24H

264 ÷ 24 = H

11 = H

The height of the box is 11 inches.
