Answer:

is 30 hope I helped!!:D

Step-by-step explanation:

step 1 : cross multiply.

10/3= k/9

(10)*(9)=k*(3)

90=3k

step 2: flip the equation.

3k =90

step 3: Divide both sides by 3.

3k/3=90/3

k=30

Answer:  (-0.4, 6.8)

The graph is attached

Step-by-step explanation:

We can find the axis of symmetry using the formula x = -b/2a

x = - -4/2(-5)

x = 4/-10

x = 0.04

Substitute for x and calculate y

y = [tex]\left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6[/tex]

y = 6.8

Answer: b. (-0.4,6.8)

Step-by-step explanation:

The number of aduir tickets sold was 44. If 2/3 of the ticket is 66 and 1/3 of the tickets is 1/3, you’ll know that by diving 66 with 3 you find the answer for the children’s ticket. 66 divide 3 is 22. But how do you find the adults ticket? Well if the rest are all adults which it is then you find the left overs. 66-22=44 and the answer will be 44. 1/3 of 66 is 22 and 2/3 of 66 is 44.

The region shaded above a solid boundary line is considered. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The line is given below.

y = 2x - 1

y > 2x - 1

Combine the equations. Then we have

y ≥ 2x - 1

The graph of the line is given below.

Answer:

The domain is the speed of the airplane.

The range is the distance travelled by the airplane.

Step-by-step explanation:

From Theory of Values, the domain of a function is the set of independent values, whereas the range of a function is set of dependent values, that is, values associated to one distinct element from domain. In this case, the independent variable is speed, whereas the dependent variable is the distance travelled by the airplane, since it is described in terms of speed.

Hence, the answer to this exercise is:

The domain is the speed of the airplane.

The range is the distance travelled by the airplane.

Answer:

139 windows

Step-by-step explanation:

you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours

Correct question

-16/5, 8, -20. What is the next term of the geometric sequence.

The nth term of a geometric sequence is expressed as:

Tn = ar^n-1

From the sequence:

a is the first term = -16/5

n is the number of term = 4(since next term is 4th term

r is the common ratio = (8)÷(-16/5) = 8×-5/16

r = -5/2

Substitute the given values into the formula

T4 = -16/5(-5/2)^4-1

T4 = -16/5(-5/2)³

T4 = -16/5×-125/8

T4 = -16/8×-125/5

T4 = -2×-25

T4 = 50

Hence the next term is 50

Answer:

[tex]m + b=2[/tex]

Step-by-step explanation:

From the question we are told that

The non separable differential equation [tex]\frac{dy}{dx} = 8x - 2y[/tex]

Generally the chi form of a give equation is mathematically represented as

[tex]\frac{dy}{dx} +P(x)y= q(x)[/tex]

[tex]\frac{dy}{dx} + 2y = 8x[/tex]

[tex]ye^2^x=\int e^2^.8xdxx[/tex]

[tex]ye^2^x=8(\frac{xe^2^x}{2}-\frac{\int e^2^x}{2})[/tex]

[tex]ye^2^x=8(\frac{xe^2^x}{2}-\frac{e^2^x}{1})+c\\[/tex]

[tex]ye^2^x=4x^2^x-2e^2^x+c[/tex]

[tex]y=4x-2+c[/tex]

for c=0

[tex]y=4x-2[/tex]

Therefore

[tex]m=4\\b=-2\\m + b=4-(+2)[/tex]

[tex]m + b=2[/tex]

The linear particular solution of the form [tex]y=mx+b[/tex] where [tex]m+b=4-2=2[/tex]

Nonseparable differential equation:

Differential equations that cannot be written  [tex]\frac{dy}{dx} =f(x)g(y)[/tex] are non-separable differential equations.

In other words, we can say those differential equations which are not separable are called non-separable differential equations.

The given equation is,

[tex]\frac{dy}{dx}=8x-2y[/tex]

This is in the form [tex]\frac{dy}{dx} +p(x)y=\phi(x)[/tex]

Here [tex]P=2, Q=8x[/tex]

So, [tex]e^{\int_{}^{}Pdx}=e^{\int_{}^{}2dx}=e^{2x}[/tex]

Therefore, the general solution is,

[tex]ye^{\int_{}^{}Pdx} =\int_{}^{}Qe^{\int_{}^{}Pdx}dx+c\\ye^{2x}=\int_{}^{}8xe^{2x}dx+c\\y=4x-2+c^{-2x}[/tex]

Step-by-step explanation:

Fitz is x years old.

Let us represent:

Fiona's age = y years old

If Fiona's is 3years younger than twice Fitz's age.

y = 2 × x - 3

y = 2x - 3

Therefore, the expression that describes Fiona's age in terms of x is

Answer:

s = 10

Step-by-step explanation:

Given s is inversely proportional to t , then the equation relating them is

s = [tex]\frac{k}{t}[/tex] ← k is the constant of proportion

To find k use the condition when s = 0.6, t = 5

0.6 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )

3 = k

s = [tex]\frac{3}{t}[/tex] ← equation of proportion

When t = 0.3, then

s = [tex]\frac{3}{0.3}[/tex] = 10

Answer:

21.1cm

Step-by-step explanation:

From sine rule which can be expressed as

b/ sinB = c/sin C

B = 57°,

b = 26 cm.

FROM THE COMPLETE QUESTION,

C=43°

Then we can substitute this

26/sin(57) = c/sin(43)

If we cross multiply and make "c" subject of the formula

c=[26 × sin(43)]/ sin57

c= 21.1 cm
