Answer:

  x = -1 and x = +1

Step-by-step explanation:

The solution to f(x) = g(x) is found where the graphs intersect.

__

Your problem statement tells you the solution:

  "The curve and the line intersects at begin ordered pair negative 1 comma 3 end ordered pair and begin ordered pair 1 comma 1.5 end ordered pair."

We interpret this statement to mean the points of intersection are ...

  (-1, 3) and (1, 1.5)

The x-values that make f(x) = g(x) are x=-1 and x=1.

Answer:

9p = 54

Step-by-step explanation:

19p = 10p + 54

Subtract 10p on both sides,

19p - 10p = 54

9p = 54

Step-by-step explanation:

my dear this is very very simple

you can definitely solve it by yourself.

just take "like terms" pit them at one side make (if a negative sign crosses to the other side of the "equal to sign" (=) it changes to positive and vice versa.

19p = 10p + 54

so grouping like terms:

10p will come and meet 19p (but it will carry the positive sign because it has crossed the '=' sign

so we have,

19p -10p = 54

since 19p and -10p are like terms so we can subtract (imagine 19 apples - 10 apples)

so we get:

9p = 54 ( 9 apples = 54)

option (A)

Hope this helps.

Ace that assignment.

Answer:

81.055 ft²

Step-by-step explanation:

A full circle has a central angle of 360°.

A sector with a central angle is 72° is 72/360 = 1/5 of a circle.

A full circle has 5 times the area of a sector with a 72° central angle.

A = 5 × 16.211 ft²

A = 81.055 ft²

The price of Burritos is $ 2.2 and the price of savory chips is $1.1

A system of equations is a set or collection of equations that you deal with all together at once.

Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.

The price of 26 delicious burritos and 27 orders of savory chips for $86.90

4 more burritos and 9 more orders of chips for $40.70

Let us consider the price of Burritos is x

and the price of savory chips is y

from the first statement we can form the equation

26*x +27*y = 86.9

and from the second statement we can form the equation

14*x + 9*y= 40.70

To determine the price of each we have to solve these system of equations.

On solving using elimination method

16x = 35.2

x = $2.2

and y = $1.1

Therefore the price of Burritos is $ 2.2 and the price of savory chips is $1.1.

Answer:

Step-by-step explanation:

39-27=12

51-39=12

63-51=12

It’s clear that ,in this sequence we add 12 each time to a term to get the next term.

This means that this is an arithmetic sequence with a common difference of 12.

Therefore,

Term1 = 27  ; Term2 = 39  ; Term3 = 51  ; Term4 = 63

Term5 = 75

Term6 = 87

Term7 = 99

Term8 = 111

Method 2 :

Un = U1 + (n-1)r

r is the common difference = 12

U1 = 27 is the first term

Then

U8 = 27 + (8-1)×12

     = 27 + 7×12

     = 27 + 84

     = 111

The Probability of a chain defect will be 3%.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Let B  be the event that brake defect .

Let C be the event that chain defect.

Since we have given that

Probability of a brake defect P(B) = 4%

Probability of both chain and brake defect P(B∩C) = 1%

Probability of either brake or chain defect P(E∪C) = 6%

So, we need to find the probability of a chain defect.

As we know the rule of probability.

P ( B U C )  =  P(A) + P (B) - P ( B [tex]\cap[/tex] C)

6   =   4   +  P (C)  - 1

P (C) = 3

Hence, Probability of a chain defect is 3%.

Answer:

x = -2/7

Step-by-step explanation:

The excluded values of the given expression are all the values of x that will make the denominator (7x + 2) = 0. This is because you cannot divide by 0...at least in algebra.

1. 7x + 2 = 0

7x = -2

x = -2/7

Therefore, x = -2/7 is the excluded value.

Answer:

3rd option

Step-by-step explanation:

[tex]\frac{14x}{7x+2}[/tex]

the denominator cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the value that x cannot be.

7x + 2 = 0 ( subtract 2 from both sides )

7x = - 2 ( divide both sides by 7 )

x = - [tex]\frac{2}{7}[/tex] ← excluded value

Step-by-step explanation:

since he was already on time on the first day, the question is reduced to the probability of being on time on exactly one of the next 2 days.

the probability to be on time on exactly one day means to be on time on one day and to be late on the other.

the probability to be late is the opposite of the probability to be on time, so

1 - 0.7 = 0.3

so, the probability for this combined event for one of the day combinations is

0.7 × 0.3 = 0.21

how many day combinations (1 day on time, the other late) can we have ? 2 (either on time on the first and late on the second, or late on the first and on time on the second).

so, we need to multiply this with the basic probability and get

0.21 × 2 = 0.42

so, b. is the right answer.

The volume of the cylinder will be equal to V=1885 cubic cm.

The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The cylinder is the right circular object with some height like bamboo, bottles, rods etc all are cylinders.

The formula for calculating the volume of the cylinder is given as:-

V=πr²H

Here we have the radius of the cylinder r= 10 cm and the height of the cylinder is H=6 cm

V=  π x (10)² x  6

V=1885 cubic cm.

Hence the volume of the cylinder will be equal to V=1885 cubic cm.

We need a maximum enlargement of n = 18 terms in order to guarantee this level of accuracy for Simpon's Rule.

The estimation of Simpson's rule follows an approach where the value of the definite integral [tex]\int\limits^a_b f{x} \, dx[/tex] is approximated by using a parabolic method of approximation for each subinterval of the interval [a, b].

The formula for calculating Simpon's rule can be expressed as:

[tex]\mathbf{\int ^b_a f(x) d \simeq \dfrac{\Delta x}{3}[y_o+4y_1+2y_2+4y_3+2y_4+...+4{y_{n-1} +y_n}}[/tex]

Given that:

[tex]\mathbf{\int ^1_0 7ex^2 dx }[/tex],

We need to determine the fourth derivative; i.e.

[tex]\mathbf{f'(x) = 14xe^{x^2}}[/tex]

[tex]\mathbf{f''(x) = 14ex^2 +28x^2e^{x^2} = (14+28x^2)e^{x^2}}[/tex]

[tex]\mathbf{f'''(x) = 56xe^{x^2} +2(14+28x^2)e^{x^2} = (84x+48x^3)e^{x^2}}[/tex]

[tex]\mathbf{f^{iv}(x) = (84+144x^2)e^{x^2} +2x(84x+48x^3)e^{x^2} = (84x+312x^2+96x^4)e^{x^2}}[/tex]

The maximum value of the 4th derivative on the interval [0,1] is:

[tex]\mathbf{f^{iv}(1) = 624e}[/tex] and the error is bounded by:

[tex]\mathbf{\Bigg| \dfrac{f^{iv}(1) (1-0)^5}{180n^4} \Bigg| = \dfrac{624e}{180n^4}=\dfrac{52e}{15n^4}}[/tex]

Now for the error to be less than 0.0001; we have:

[tex]\mathbf{\dfrac{52e}{15n^4} < 0.0001}[/tex]

[tex]\mathbf{52e < 0.0015n^4}[/tex]

[tex]\mathbf{n^4 > \dfrac{52e}{0.0015}}[/tex]

[tex]\mathbf{n > \sqrt[4]{ \dfrac{52e}{0.0015}}}[/tex]

n ≅ 17.52.

Therefore, we can conclude that we need a maximum of n = 18 terms in order to guarantee this level of accuracy for Simpon's Rule.

Step-by-step explanation:

The value of the trigonometry equation (sin 60)(cos 30)+(cos 60)(sin 30) is sin (60+30). Option J is correct.

The formula of sum of sin (a+b) is the trigonometry identity which is used to solve and simplify the problem based on trigonometry equation.

The formula of sum of sin (a+b),

Sin(A+B)=(sin A)(cos B)+(cos A)(sin B)

Here, (A and B) are the measure of angles.

The trigonometry equation given in the problem is,

(sin 60)(cos 30)+(cos 60)(sin 30)

Compare this expression with the above formula we get,

A=60

B=30

Thus, the value of the given expression is,

(sin 60)(cos 30)+(cos 60)(sin 30)=sin (60+30)

Thus, the value of the trigonometry equation (sin 60)(cos 30)+(cos 60)(sin 30) is sin (60+30). Option J is correct.
