Answer:

46.8 cm²

Step-by-step explanation:

The diagonal of the square has length \(\sqrt{6^2+10^2}=2\sqrt{34}\). Therefore, the radius of the circle is \(\sqrt{34}\), meaning the area is \(\pi(\sqrt{34})^2 \approx 34(3.14)=106.76\).

The area of the rectangle is \((6)(10)=60\) cm².

Subtracting the areas, the answer is 46.76 cm², which is 46.8 cm² to the nearest tenth.

Answer:

9.) A= 23mm².

P= 20mm.

T= PARALLELOGRAM.

Step-by-step explanation:

9.) A=(5+5) × 1/2 × 4.6

= (10) × 1/2 × 4.6

= 5mm× 4.6 mm

= 23mm².

P=(5+5+5+5)

= 20mm.

T= PARALLELOGRAM.

Step-by-step explanation:

The series of numbers that meets the 

requirements is 5+6+8+9+4+6+7+3+9+2+8+9+1.

How to check that the series meets the requirements?

To verify that the series meets the requirements, we must establish what the requirements are:

●Every 3 consecutive numbers must add up to 19.

●In total there must be 14 numbers.

●The total sum of all the numbers must be 77

To verify that every 3 consecutive numbers add  up to 19, we separate them into 4 groups of 3 and one number is left over.

5 + 6 + 8 = 19

9 + 4 + 6 = 19

7 + 3 + 9 = 19

2 + 8 + 9 = 19

In total there must be 14 numbers and they must add up to 77.

5+6+8+9+4+6+7+3+9+2+8+9+1 = 77

Answer:

The sum of the outer angles of polygon is twice the sum of the inner angles. (i) How many sides does it have? (ii) What if the sum of outer angles

Answer:

135 cm

Step-by-step explanation:

Let Jose's height = x

The mean of their heights = 150

Given the Heights:

150cm, 170cm, 140cm, 155cm

The mean is the sum if the heights divided by the number of people

Here :

(150 + 170 + 140 + 155 + x) / 5 = 150

(615 + x) / 5 = 150

615 + x = 750

x = 750 - 615

x = 135 cm

Answer: X= 108125 and  Y  = 373125.

Step-by-step explanation:

Given system :

\(X= 33500+0.2Y (i)\\\\ Y=26500+0.1X (ii)\)

Consider (ii)

\(Y=26500+0.1X\\\\\Rightarrow\ Y-0.1X=26500\)

Multiply 10 on both sides , we get

\(10Y-X=265000 (iii)\)

Add (i) and (iii)

\(10Y= 33500+26500+0.2Y\\\\\Rightarrow\ 10Y-0.2Y= 298500\\\\\Rightarrow\ 0.8Y= 298500\\\\\Rightarrrow\ Y=\dfrac{298500}{0.8}\\\\\Rightarrrow\ Y=373125\)

Put this in (i)

\(X= 33500+0.2(373125) =108125\)

Hence, X= 108125 and  Y  = 373125.

The equation of the polynomial P3 is  p3​(t) = 5/6t³− 17/6t​

Equation:

In algebra, an equation consists of variable, number and constants.

Given,

Here we need to find the polynomial P3 such that {P0, P1, P2, P3} is an orthogonal basis for the subspace P3 of P4.

And the scale the polynomial p3 so that its vector of values is (-1,2,0, -2,1).

Here we know that the polynomial (before the scaling) p3​ is just the difference between t³ and its orthogonal projection on the span of 1,t,t²−2.

Then we showed that the projection is ​, hence

p3​(t) = t³− 17/5t​

When here we have the  scale this polynomial such that the vector of values at t=−2,−1,0,1,2 is (−1,2,0,−2,1).

Now, we need to find the scalar α, it can be written as,

=> α⋅p3​(−2)=−1

=> α⋅p3​(−1)=2

=> α⋅p3​(0)=0

=> α⋅p3​(1)=−2

=> α⋅p3​(2)=1

Here from the 4-th equation we have the value of

=> α⋅(1- 17/5) = -2

=> α = 5/6​

And it is easy to check that all the equations are satisfied with this α.

Therefore, the required polynomial p3 is

=> p3​(t) = 5/6(t³− 17/5t​)

=> p3​(t) = 5/6t³− 17/6t​

Using the Pythagorean Theorem and implicit differentiation, it is found that the distance between them is increasing at a rate of 2050 km/h when they are 0.5 hours away from the harbor.

The Pythagorean Theorem relates the length of the legs \(l_1\) and \(l_2\) of a right triangle with the length of the hypotenuse h, according to the following equation:

\(h^2 = l_1^2 + l_2^2\)

For this problem, we have that since the ships are moving west and north, the distance between them as a function of the time will be given by the hypotenuse of a right triangle, as follows:

d² = x² + y².

In which;

Applying implicit differentiation, the rate of change of the position is given as follows:

\(2\frac{dd}{dt} = 2x\frac{dx}{dt} + 2y\frac{dy}{dt}\)

\(\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}\)

From the velocities, we have that:

\(\frac{dx}{dt} = 40, \frac{dy}{dt} = 50\)

From the velocities, and the time of half an hour, the positions are given as follows:

x = 0.5 x 40 = 20, y = 0.5 x 50 = 25.

Hence:

\(\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}\)

\(\frac{dd}{dt} = 20(40) + 25(50)\)

dd/dt = 2050.

The distance between them is increasing at a rate of 2050 km/h when they are 0.5 hours away from the harbor.

Using probability we know that we have full probability or 1 that we will draw a coin that will have ethe value of at least $0.10.

A probability is a numerical representation of the likelihood or chance that a specific occurrence will take place.

Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Simply put, probability is the likelihood that something will occur.

When we don't know how an occurrence will turn out, we can discuss the likelihood or likelihood of various outcomes.

So, we have the chart:

Penny = 2/5 = 0.4

Nickel = 1/5 = 0.2

Dime = 1/4 = 0.25

Then, the probability of getting a value of at least $0.10

P(E) = 3/3

P(E) = 1

Therefore, using probability we know that we have full probability or 1 that we will draw a coin that will have ethe value of at least $0.10.

Step-by-step explanation:

Although I cannot find any model or solver, we can proceed to model the optimization problem from the information given.

the problem is to maximize profit.

let desk be x

and chairs be y

400x+250y=P (maximize)

4x+3y<2000   (constraints)

according to restrictions y=2x

let us substitute y=2x in the constraints we have

4x+3(2x)<2000

4x+6x<2000

10x<2000

x<200

so with restriction, if the desk is 200 then chairs should be at least 2 times the desk

y=2x

y=200*2

y=400

we now have to substitute x=200 and y=400 in the expression for profit maximization we have

400x+250y=P (maximize)

80000+100000=P

180000=P

P=$180,000

the profit is $180,000

Step-by-step explanation:  y=logax and it's a reflection of an exponential curve that curves up and a logarithmic function curves down.

The interval where function f(x) is negative and greater than 0 is (-∞, -3) U (-1.1, 0)

We have,

The function f(x) crosses the x-axis at (-3, 0), (-1.1, 0), and (0.9, 0), it means that f(x) is negative for x values less than -3, between -1.1 and 0.9, and greater than 0.

Therefore, we can say that:

f(x) < 0 for x < -3 and -1.1 < x < 0.9

And,

The function f(x) has a minimum value of (0, -3) and a maximum value of (-2.4, 17).

This means that f(x) is positive for x values greater than -2.4. Therefore, we can say that:

f(x) > 0 for x > -2.4

Now,

Combining these inequalities, we can say that f(x) is negative over the intervals (-∞, -3) and (-1.1, 0.9), and positive over the interval (-2.4, ∞).

So,

The interval where f(x) is negative and greater than 0 is:

(-∞, -3) U (-1.1, 0)

Thus,

The interval where f(x) is negative and greater than 0 is (-∞, -3) U (-1.1, 0)
