Use The Quadratic Formula To Solve For X. 5x + 4x=4 Round Your Answer To The Nearest Hundredth. If There

Answers

Answer 1
x=0.58, x= -1.38

Quadratic formula is:
(-b-/+ sqrt b^2-4ac)/2a

We need to get the function to equal zero so we subtract 4 from both sides.

5x^2+4x-4=0 is out new equation.

a=5, b=4 and c=-4

Now we can solve by plugging in the variables!

-4+ sqrt 4^2-4(5)(-4)/2(5)= 0.5797

Do the same with subtracting because of the plus OR minus

-4-sqrt 4^2-4(5)(-4)/2(5)= -1.3797

Rounded to the nearest 100th will be:

x= -1.38, x=0.58

You can check your answer by plugging them back into the original function— you should get zero. :)

If a rocket travels 68,732 milometers in 3 hours, what is it's speed?
a) 23,000 Km/hr
b) 23,000 hr/km
c) 22,910 hr/km
d) 22,911 km/hr

Answers

Answer:

v = 0.0229 km/h

Step-by-step explanation:

Given that,

Distance, d = 68,732 milometers = 0.0687 km

Time, t = 3 hours

We need to find the speed of the rocket. The speed of an object is given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{0.0687}{3}[/tex]

v = 0.0229 km/h

So, the speed of the rocket is 0.0229 km/h.

The required value of x = 12 and the side length of the triangle is 12 units. which is determined by Pythagoras's theorem.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one angle is equal to the sum of the squares of the other two sides.

The given triangle is a right-angled triangle.

As per Pythagoras's theorem,

⇒ a² + b² = c²

Here a = 16, b = x and c = 20

Substitute the values in the formula,

⇒ 16² + x² =20²

⇒ 256 + x² = 400

⇒ x² = 400 - 256

Apply the subtraction operation,

⇒ x² = 144

⇒ x = √144

⇒ x = 12

Therefore, the required value of x is 12 units.

Solve the following quadratic equation for all values of x in simplest form.
20+ 2x= 28

Answers

Answer:

x = 4

Step-by-step explanation:

To solve, we need to isolate x.

Start by moving the 20 to the other side by subtracting it from both sides.

2x = 8

Since x is being multiplied by 2, we need to divide both sides by 2 to move it to the other side.

x = 4

Find the volume of the beach ball and the volume of the toy ball. How many times greater is the volume of the beach ball than the volume of the toy ball?
A.THE VOLUME OF THE BALL IS 904 CUBIC INCHES. b. THE VOLUME OF THE BEACH BALL IS 678 CUBIC INCHES. c.the volume of the beach ball is 452 cubic inches

Answers

Answers:

Volume of beach ball = 904 cubic inchesVolume of toy ball = 113 cubic inchesThe beach ball is 8 times greater compared to the toy ball

===============================================

Work Shown:

Beach ball

V = volume of sphere

V = (4/3)*pi*r^3

V = (4/3)*3.14*(6)^3 .... the beach ball has diameter 12, so radius is 6

V = 904.32

V = 904 cubic inches is the approximate volume of the beach ball

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

Toy ball

V = volume of sphere

V = (4/3)*pi*r^3

V = (4/3)*3.14*(3)^3 .... the toy ball has diameter 6, so radius is 3

V = 113.04

V = 113 cubic inches is the approximate volume of the toy ball

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

Divide the two volumes to find that 904/113 = 8

This means that the beach ball is 8 times greater in volume compared to the toy ball

We can say

[tex]\text{Beach ball volume} = 8*\left(\text{toy ball volume}\right)[/tex]

The beach ball's volume is 7238.23and if we round that would be 7238 and the volume for the toy ball is 904.78 and if we round that it would be 905.So, it's around 7 times greater. The difference after they are rounded is  6,333.

Hope this helps.

(dont put the cm² in your answer though since its already there)

Step-by-step explanation:

Surface area of the cardboard part formula :

6 x 10.5= 63cm²

Plastic part of the can :

Make a table with the following information:
Cans: 0, 2, 4, 6
Cost:


Equation:

Answers

Answer:

$12,$11,$10,$9

Step-by-step explanation:

As the starting price is $12, the first piece of information they give you is the number of cans + the discount each one gives, meaning that the table should have two titles being cost and cans. The number of cans should be at the top with the price being put below for example.

cans:  0    2   4    6

cost:  12   11   10   9

that is the table; the equation to figure this out would be

if you say that 1 can is = to "x"

then the equation becomes much easier to write down and you can simply write it down for each price

cost = 12

cost = 12 - 2x = 11

cost = 12 - 4x = 10

cost = 12 - 6x = 9

making x worth 0.5

What is the measure of the angle that the ladder makes with the wall?

Answers

Answer:

30°

Step-by-step explanation:

The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)

Measure of angle the ladder makes with the ground = 180 - 120 = 60°

Therefore,

The measure of angle the ladder makes with the wall = 180 - (60 + 90°)

same rectangle, but from B to C to D to A,
a distance of only 31 metres.
What is the area, in square metres, of rectangle ABCD?
D
С

Answers

Answer:

168 meters squared

Step-by-step explanation:

So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.

So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m

38-14=24

so now we know that the side is 24 and we can solve for the area

24*7=168

so the answer is 168 meters squared

Okay let’s put PEMDAS into mind.

PEMDAS: parenthesis, exponents, multiplication, division, addition, subtraction (left to right)

Multiplication & Division comes first (left to right) so...

-9•(-4) = 36

bring down the divided by 3...

36/3 = 12

Bring the whole equation down...

18+12+10•2

Once again, there is another to multiply so...
