Answer:

60 .

Step-by-step explanation:

Normal pay for 4 hours = 10 * 4 = 40.

Overtime for 4 hours = 40 *  1 1/2

= 60.

Tim was paid 15 for his overtime.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Normal pay of Tim= 10

Overtime hours= 4

and, overtime pay = 1 1/2 of 10

So, the overtime pay

= 3/2 of 10

= 3/2 x 10

= 15

Hence, Tim was paid 15 for his overtime.

Answer:

No there is a remainder of -512

Step-by-step explanation:

Divide (x+7) into (x^3 - 3x^2 + 2x - 8)

x^2-10x+72 R -512/(x+7)

According to the Factor theorem,  (x+7)  is not a factor of f(x) = x^3 − 3x^2 + 2x − 8.

The theorem is as follows: A polynomial f(x) has a factor (x−p) if and only if f(p)=0.  

Consider, f(x) = x^3 − 3x^2 + 2x − 8

Here, the expression we have is (x + 7), so we have to find f(-7) in order to check if (x+7) is a factor of f(x) or not

Here,  p = −7  

Now, lets check

f(−7)=(−343)−3(49)−14−8  

f(−7)=−343−147−14−8  

f(−7)=−512, which is not equal to 0  .

So, According to the Factor theorem,

(x+7)  is not a factor of f(x) = x^3 − 3x^2 + 2x − 8.

Answer:

y = -x - 1

Step-by-step explanation:

hello,

this is a line, right?

So the equation should be something like

y = ax+b and we need to find a and b

we can see that the points (-1,0) and (0,-1) are in the line so we can write

0 = a*(-1) + b <=> b - a = 0 <=> a = b

-1 = a*0 + b <=> b = -1

so the equation is

y = -x - 1

Answer:

y = - x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (0, - 1)

m = [tex]\frac{-1-1}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = - x - 1 ← equation of line

[tex]\approx[/tex] 57 gallons

Step-by-step explanation:

Given:

Silo needs to be painted.

Height of silo = 80 feet

Diameter of silo = 20 feet

One gallon of paint covers 100 sq ft

To find:

Gallons of Paint required to paint the outside of silo = ?

Solution:

We need to first calculate the lateral surface area(LSA) of this cylinder shaped silo.

[tex]LSA = 2\pi rh[/tex]

where r is the radius and

h is the height of cylinder.

[tex]r = \dfrac{Diameter}2\\\Rightarrow r = 10\ ft[/tex]

Putting the values in formula:

[tex]LSA = 2\times 3.14\times 10\times 80\\\Rightarrow LSA = 5024\ sq \ ft[/tex]

Total surface area of cylinder = LSA + 2 [tex]\times[/tex] Area of base

Total surface area of cylinder = LSA + 2 [tex]\times[/tex] [tex]\pi r^{2}[/tex]

TSA = [tex]5024 +2 \times 3.14 \times 10^2 = 5024 +628=5652\ sq \ ft[/tex]

100 sq ft requires number of gallons = 1

5652 sq ft requires number of gallons:

Q1; 10 units

The dotted lines separate the figure into 3 shapes - 1 square, 2 triangles.

The area of a square is s^2, where s is the side length.

The side length of the square is 2. 2^2 =4

The area of the square is 4 units.

The area of a triangle is bh/2, where b is the base and h is the height.

The base of the triangle on the left is 2 and the height is also 2. 2(2)/2 =2

The area of the left triangle is 2 units.

The triangle on the right has a base of 2 and a height of 4. 4(2) =8 /2 = 4

The area of the right triangle is 4 units.

The area of the composite figure is the area of the 2 triangles and the square added together; 4+2+4 =10

The area of the figure is 10 units.

Q2: The area of the shaded area is 44.2654825 [tex]cm^2[/tex].

The area of a circle is π[tex]r^2[/tex]. The radius of this circle is 4cm.

Therefore, the area of the circle is 16π[tex]cm^2[/tex].  

The formula for area of a rectangle is length times width. The length of this rectangle is 3 and the width is 2.

Therefore, the area of the rectangle is 6 cm^2

We're looking for the area of the shaded region (area of circle- rectangle), so we subtract the area of the rectangle from the area of the circle.

16π simplifies to 50.2654825 cm^2.

50.2654825-6 = 44.2654825 cm^2

The area of the shaded area is 44.2654825 [tex]cm^2[/tex].

6x - 4x = 6 + 1

2x = 7

x = 7/2

Plug in x as 7/2 in one of the side lengths.

6(7/2) - 1

42/2 - 1

21 - 1 = 20

Answer:

Step-by-step explanation:

Sides of a square are always equal.

6x - 1 = 4x + 6

Move the variable to L.H.S and change its sign

6x - 4x - 1 = 6

Move the constant to RHS and change its sign.

6x - 4x = 6 + 1

Simplify

2x = 7

Divide both sides by 2

2x/2 = 7/2

X = 7/2

Again,

6x - 1

plugging the value of X

= 6 * 7/2 - 1

= 3 * 7 - 1

= 21 - 1

= 20

Step-by-step explanation:

c^2=81

Take the square root of both sides.

The square root of c^2 is c.

The square root of 81 is 9.

c=9

Answer:

C = 9 centimeters

Step-by-step explanation:

First, look at the area of a square, which formula is c^2 or in standard format - s^2. Thus, we can say, c^2 = 81. Then, we can simplify, and put c = √81. Since 81 is a perfect square, 9 *  9 = 81. Thus the answer is 9 centimeters.

Answer:

A) f(x)

Step-by-step explanation:

f(x) has 4 x-intercepts, becoz it "cross" the x axis 4 times.

g(x) would have an infinite number of intercepts coz it is a cos function, but it gave a limit to the domain which is 0 to 2[tex]\pi[/tex], so it only has 2 x-intercepts.

h(x) is the degree of x^3, so in theory, it has 3 x-intercepts.

The function that has the most x-intercept is given by: Option A: f(x)

The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function.

The x-intercept for a function y = f(x) is a solution to the equation f(x) = 0 becuase at that value of x, the function f(x) lies on x-axis, where y is 0. Values of x-intercept for a function f(x) are also called roots or solution of f(x) = 0 equation.

Suppose that we've got a polynomial function as y = p(x),

where p(x) is of degree n (the highest power its variable pertains in any of its composing terms).

Then, the maximum number of roots it can possess for p(x) = c (c is a constant), or p(x) - c = 0 is n

So, the number of roots of p(x) - c = 0 cannot exceed the degree of p(x).

From the graph, we see that:

f(x) intersects x-axis at 4 places, so it has 4 x-intercepts.

g(x) intersects the x-axis at 2 places as in the graph, and therefore, it has 2 x-intercepts.

h(x) is a polynomial of degree 3. The maximum number of intercepts it can have is the maximum number of roots h(x) = 0 can have which is 3(the degree of h(x) ). So it cannot be bigger than 3.

Thus, the function that has the most x-intercept is given by: Option A: f(x)

(c)The price of milk next year will be: $4.76

(d)5 years

Step-by-step explanation:

The price of a gallon of milk has been rising about 1.36% per year since 2000.

(a)Since the price grows by a percentage (or constant factor) each year, an exponential function would be best to model the scenario.

(b)The exponential growth model is given as:

[tex]P(t)=P_0(1+r)^t$ where:\\P_0$=Initial Price\\r=Growth factor\\t=time (in years, for this case)[/tex]

The independent variable in the function is t. This represents the number of years since 2000.

(c)

[tex]I$nitial Price, P_0=\$4.70\\r=1.36\%=0.0136\\P(t)=4.70(1+0.0136)^t\\\\P(t)=4.70(1.0136)^t[/tex]

Therefore, the price of milk next year will be:

[tex]P(1)=4.70(1.0136)^1=\$4.76[/tex]

(d)We want to determine how long it will take for the price to top $5.

P(t)=$5

[tex]5=4.70(1.0136)^t\\$Divide both sides by 4.7$\\(1.0136)^t=\frac{5}{4.7} \\$Change to logarithm form\\t=Log_{1.0136}\frac{5}{4.7}\\t=4.58[/tex]

Therefore, in exactly 4.58 years, the milk price would be $5. Therefore, by the 5th year, the milk price would top $5.

Outliers are important because they are numbers that are "outside" of the Box Plot's upper and lower fence, though they don't affect or change any other numbers in the Box Plot they are still important.

If you want to find your fences you will first take your IQR and multiply it by 1.5. I call this your "magic number".

Lower fence: Take your Q1 and subtract it from your magic number, that number your get is your lower fence.

Upper fence: Take your Q3 and add it to your magic number, that number you get is your upper fence.
