Answer:

distance divided by time

Step-by-step explanation:

distance is the speed of the moving object multiplied by the time taken to complete a certain distance therefore the speed is the distance covered divided by the time taken.

Answer:

Step-by-step explanation:

Answer:

sin x° = opposite ÷ hypotenuse

Step-by-step explanation:

Cosine is represented by the expression adjacent ÷ opposite and sine is represented by opposite ÷ hypotenuse. Only the fourth option lines up with the functions defined above.

If you are having trouble remembering the ratios for each trig function, you can use the acronym SohCahToa. This stands for:

S - sine

o - opposite

h- hypotenuse

C - cosine

a - adjacent

h - hypotenuse

T - tangent

o - opposite

a - adjacent

Answer:

A

Step-by-step explanation:

F(x) = 4x^2 + 1

G(x) = x^2 - 5

(F-G)(x) = (4x^2+1 - x^2-5)

collect like terms

(F-G)(x) = (4x^2-x^2 + 1-5)

= (3x^2 - 4)

Answer:

11. = D) x is greater than or equal to -1

12. = A) x is less than -2

Step-by-step explanation:

Answer:

11. -1 ≤ x

or

x ≥ -1, D

Because it is starting at -1, and the arrow is pointing up showing that x is greater than. BUT the circle is not hallow and is filled meaning that is is greater than, OR EQUAL TOO.

12. X < -2, A

Because it is starting at -2 and is going down showing that -2 is greater, and since the circle is hallow it just means X is less than NOT OR EQUAL TOO.

Answer:

option 2, because g-h and j -k is congruent

Answer:

Following are the solution to the given question:

Step-by-step explanation:

For point a:

[tex]6.5 - 4.9 = 2.4 \\\\\frac{2.4}{1.2} = 2 \\\\\sigma \ \ so \ k = 2[/tex]

For point b:

[tex]\frac{3}{1.2}\ \ \sigma\ \ so \ k =\frac{3}{1.2} \ \ so\ \ 1- \frac{1}{k ^2} = 0.84[/tex]

For point c:

Once again, we have k = 2 though with Chebyshev discrepancy of witness numbers in the same number of standard deviations off mean = at least 75 percent.

Answer:

(x - 5)(x + 2)(x + 5)

Step-by-step explanation:

x³ + 2x² - 25x - 50

x³ + 7x² - 5x² - 35x + 10x - 50

x(x² + 7x + 10) - 5(x² + 7x + 10)

(x - 5)(x² + 7x + 10)

(x - 5)(x² + 2x + 5x + 10)

(x - 5)(x(x + 2) + 5(x + 2))

(x - 5)(x + 2)(x + 5)

Answer:

[tex]y = \frac{3}{4}x - 3[/tex]

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

[tex]y = \frac{3}{4}x + b[/tex]

If it passes through (4, 0), than y = 0 when x = 4

[tex]y = \frac{3}{4}(4) + b[/tex]

[tex]y = 3 + b[/tex]

[tex]b = -3[/tex]

Therefore, the equation is [tex]y = \frac{3}{4}x - 3[/tex].

Answer:

3

Step-by-step explanation:

How many times will Gus need to fill the bucket to completely fill the fish tank if he doesn’t spill a drop? Use 3.14 for pi

Number of times = volume of tank /volume of cylinder

volume of cylinder = πr²h

3.14 x 5² x 20 = 1570

4710 /  1570 = 3 times

Answer:

The answer is 3418.1 ft rounded to the nearest tenth.

Step-by-step explanation:

The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.

The area of the circular base can be calculated as

[tex]\pi \times {r}^{2} [/tex]

where r is the radius of the circular base, which is 8 ft.

The area of the circular base is

[tex]\pi \times {8}^{2} = 64\pi[/tex]

We also know the height of the cylinder is 17 ft.

Hence, the volume of the cylinder is

[tex]64\pi \times 17 = 1088\pi = 3418.0528...[/tex]

This will be rounded up to 3418.1 with the nearest tenth

Answer:

Perimeter = AB + AC + BC = 26.55 units

Step-by-step explanation:

The perimeter of a triangle is the sum of lengths of all sides.

Here we have a right triangle, right-angled at C

angle B = 46°

AB = 11

We continue to calculate

AC = (11)sin(46°) = 7.91

BC = (11)cos(46°) = 7.64

Perimeter = AB + AC + BC = 26.55 units

Answer:

Answer:

Total number of balls  = 9

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by a, b, and c.

The sum of the three is 103. Thus, we can write that:

[tex]a+b+c=103[/tex]

The second number is five less than the first. So:

[tex]b=a-5[/tex]

And the third number is four times the first. So:

[tex]c=4a[/tex]

Substitute:

[tex]a+(a-5)+(4a)=103[/tex]

Solve for a. Combine like terms:

[tex]6a-5=103[/tex]

Add five to both sides:

[tex]6a=108[/tex]

And divide both sides by six. Therefore:

[tex]a=18[/tex]

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

Answer:

m<SRW = 95degrees

Step-by-step explanation:

If a line with points T, R, W intersects a line with points S, R, V at point R with the point of intersection at R, this means that;

m<TRV = m<SRW  (vertically opposite angles)

Since m<TRV = 95 degrees, hence <SRW = 95degrees

Answer:

constant: 4

coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)

Step-by-step explanation:

coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression

therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.

constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.

therefore, 4 is a constant.

Step-by-step explanation:

[tex]12x {}^{2} + 4x - 3x - 1 = 0 [/tex]

[tex]4x \times (3x + 1) - (3x + 1) = 0[/tex]

[tex](3x + 1) \times (4x - 1) = 0[/tex]

[tex]3x + 1 = 0 \\ 4x - 1 = 0[/tex]

[tex]x = - \frac{1}{3} \\ x = \frac{1}{4} [/tex]
