Which polynomial is a quartic trinomial?
A. -x^4-5x^2 + 1
B. x^2 + 4
C. x^3 + 2x^2 - 8x + 16
D. 3x^5 + 7x^2 - 9x^4

Answer:

x ≤ -7

Step-by-step explanation:

On the graph we can see that:

-the pink solid line is where x= -7 and y can have any value, so is either first or second choice.

-the pink area includes numbers that are equal or less then -7 ( such as -8, -9,-10,...) so the inequality must be x ≤ -7 (the second choice. )

See the line is parallel to y axis

So

X is constant -7

Hence the inequality is

Answer:

A ≈ 8.6 ft²

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] × 7 × 3 × sin55°

  = [tex]\frac{1}{2}[/tex] × 21 × sin55°

  = 10.5 × sin55°

  ≈ 8.6 ft²( to 1 dec. place )

The predicted strength is an illustration of a linear regression

The predicted strength of a weld with a diameter of 51 is -503.2

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988*Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988*51

Evaluate the sum

Strength = -503.1604

Approximate

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2

The predicted strength is an illustration of linear regression.

The predicted strength of a weld with a diameter of 51 is -503.2.

Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988 × Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988 × 51

Strength = -941.6992 + 438.5898

Strength = -503.1604

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2.

* means multiplied by

radius is half of a diameter

circumference of a circle is pi multiplied by diameter

area of a circle is pi multiplied by radius squared

1. radius is 7.4 divided by 2 which is 3.7

radius of 3.7 squared is 13.69

pi multiplied by 13.69 is 43.01

2. diameter is radius times 2

2.2 times 2 is 4.4

ℼ * 4.4 = 13.82

3. pi*5=15.71

4. pi*6=18.85

5. 2.1*2.1 = 4.41 -> pi*4.41 = 13.85

year3 girl built same igloo=3/7

To find out all together how much have built =3/4+3/7

if we take alceam

in fraction down we need to make 28

so 3/4 we multiply by 7 and 3/7we multiply by 4

Answer:

  102.8 cm

Step-by-step explanation:

The perimeter of a semicircle is the sum of the length of the diameter and the length of the curved edge. The curved edge is half the circumference of a circle with the same radius.

  perimeter = diameter + curved edge

  = 2r +1/2(2πr) = r(2 +π)

  = (20 cm)(2 +π) ≈ 102.8 cm

The perimeter of the window is about 102.8 cm.

x=145 and y=35

Step-by-step explanation:

the hole line equals 180 so do 35-180 which equals 145 and y would equal 35

The value of the expression n² + 26n + 88 is equivalent to negative 4 and negative 22.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is n² + 26n + 88

Put that expression to get the solution

          n² + 26n + 88 = 0

 n² + 22n + 4n + 88 = 0

n(n + 22) + 4(n + 22) = 0

          (n + 4)(n + 22) = 0

The value of n is negative 4 and negative 22.

1000 ————. 4. - — — — — — — 5

1500 — — — —5 — — — — — ,— —?

If work increase, no.of people needed more

So, the required ratio is 1500/1000

If work men increase, no of hours decrease

Answer:

Formula for volume of cylinder;

V = π[tex]r^{2}[/tex]h

Where 'π' represents pi(22/7 or 3.14), 'r' represents the radius which is 1/2 x diameter (half of diameter = radius) which is squared, and 'h' which represents the height.

To find the radius of the diameter 5, we must find 1/2 of 5:

1/2 x 5

5/2 = 2.5 is our radius.

Now we plug these into our equation:-

V = π[tex]r^{2}[/tex]h

V = 3.14(2.5^2) x 20

V = 3.14(6.25) x 20

V = 19.625 x 20

V = 392.5 cubic feet.

Answer:

9 boxes

Step-by-step explanation:

As the truck is 7.5 ft long, we can fit 3 boxes of paper along the length since 7.5 ÷ 2.5 = 3

As the truck is 4 ft wide, we can only fit 1 box of paper along the width

since 4 ÷ 2.5 = 1.6

As the truck is 8 ft tall, we can fit 3 boxes of paper high

since 8 ÷ 2.5 = 3.2

Therefore, the number of boxes of paper is:
