Which graph represents the function g(x) = |x + 4| + 2?

[tex]\log_96561=4[/tex]

Answer: i cant read that m8 take a better picture

Step-by-step explanation:

The solution is:: the area cross sectional area of triangle form in the cone is 80ft²

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Given in the question,

radius of cone's base = 8ft

             cone's base = base of triangle

height of cone = 10 ft

height of cone = height of triangle

Area of triangle

Area = 1/2(h)(b)

here h = height of triangle

       b = base of triangle

A = 1/2(8)(10)

A = 40ft²

Since the section is 2 similar triangles back to back around the vertical center

so the area cross sectional area of triangle form in the cone is 2(40)ft² = 80ft²

Answer:

Choice B. sin(B)=cos(90-B)

Step-by-step explanation:

That cofunction identity is the one you looking for...choice B.

If you aren't convinced or don't know that identity, then maybe this will help:

90-B is actually the same thing as saying A for this right triangle since A+B=90.

So choice B basically says sin(B)=cos(A)

Well let's find both sin(B) and cos(A)

sin(B)=b/c

cos(A)=b/c

Those are the same ratios!

So they are equal!

Answer:

option B

Step-by-step explanation:

from the given options

a)      sin (B)  = sin (A)

b)      sin (B ) = cos (90° - B)

        cos (90° - B ) = Sin B

c)       cos  (B ) =  sin(180° - B)

         sin(180° - B) = sin (B)

d)        cos (B)  = cos(A)

so, we can clearly see from the above solution that option B is correct.

As 90° - B is in first quadrant and in first quadrant sign of cos dose not change  and 90 is multiple of odd so 'cos' changes to 'sin'

Answer:

b

Step-by-step explanation:

We're looking for a model of the form

[tex]y=a\cos(b(x-c))+d[/tex]

[tex]a[/tex] is the amplitude, equal to half the difference between the maximum and minimum hours of daylight:

[tex]a=\dfrac{15.3-9.1}2=3.1[/tex]

[tex]b[/tex] determines the period of the cosine function. The period itself is [tex]\dfrac{2\pi}b[/tex], which we want equal to 365, so that

[tex]365=\dfrac{2\pi}b\implies b=\dfrac{2\pi}{365}[/tex]

(so that the value in the second box should be 365)

[tex]c[/tex] determines the horizontal shift of the cosine function. We'll come back to this in a moment.

[tex]d[/tex] represents the vertical shift of the function. The standard function is bounded between -1 and 1:

[tex]-1\le\cos x\le1[/tex]

Our new function has an amplitude of 3.1, so that

[tex]-3.1\le3.1\cos x\le3.1[/tex]

We want the range of values to fall between 15.3 and 9.1, so we want to pick [tex]d[/tex] such that

[tex]\begin{cases}-3.1+d=9.1\\3.1+d=15.3\end{cases}\implies d=12.2[/tex]

So the current model is

[tex]y=3.1\cos\left(\dfrac{2\pi}{365}x\right)+12.2[/tex]

[tex]c[/tex] represents the horizontal shift of the function. [tex]x=0[/tex] represents the first day of the year, which according to the current model tells us we should expect [tex]3.1\cos0+12.2=15.3[/tex] hours of daylight on the first day of the year. But this conflicts with the data. We want this maximum to occur on the 172nd day of the year, so we shift the model by this amount, and the model is

[tex]y=\boxed{3.1}\cos\left(\dfrac{2\pi}{\boxed{365}}}(x-\boxed{172})\right)+\boxed{12.2}[/tex]

Answer:

3n=5d and 3n = 5d and 3n + 6 = 2d + 4

Step-by-step explanation:

Answer:  The correct option is

(A) [tex]5n=3d~~~\textup{and}~~~3n+6=2d+4.[/tex]

Step-by-step explanation:  Given that the numerator and denominator of a fraction are in the ratio of 3 to 5. When the numerator and denominator are both increased by 2, the fraction is equal to \dfrac{2}{3}.

We are to select the system of equations that could be used to solve the problem.

Since n denotes the numerator and m denotes the denominator of the given fraction, so we have

[tex]\dfrac{n}{d}=\dfrac{3}{5}\\\\\\\Rightarrow 5n=3d,[/tex]

and

[tex]\dfrac{n+2}{d+2}=\dfrac{2}{3}\\\\\\\Rightarrow 3(n+2)=2(d+2)\\\\\Rightarrow 3n+6=2d+4.[/tex]

Thus, the required system of equations is

[tex]5n=3d~~~\textup{and}~~~3n+6=2d+4.[/tex]

Here is the set up:

Let p = percent of change

(72 - 14)/72 = p/100

Solve for p.

Answer:

P = 1.44 Watts

Step-by-step explanation:

We know that the relation between voltage and current in a simple circuit with a resistor is

V = I.R

Where

V = the voltage of the source

I = current of the circuit

R = resistance

The power is defined as

P = V.I

Which is the same as

P = V.(V/R)

P = (24 v)^2 / (400 ohm)

P = 1.44 Watts

The answer is:

The airplane will travel 8800 feet in 10 seconds.

It's a conversion exercise, we need to be careful in order to solve it with no mistakes.

First:

We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

[tex]Time=1hour*\frac{60minutes}{1hour}*\frac{60seconds}{nminute}=3600seconds[/tex]

Second:

We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.

So, solving we have:

[tex]Speed=600\frac{miles}{hour}*\frac{1hour}{3600seconds}*\frac{5280ft}{1mile}=880\frac{ft}{seconds}[/tex]

Now, calculating how many feet does it travel in 10 seconds, we have:

[tex]distance=speed*time\\\\distance=880\frac{ft}{seconds}*10seconds=8800ft[/tex]

We have that the airplane will travel 8800 feet in 10 seconds.

The equation to determine the temperature in Bangor is 3x + 22 = 82. Solving the equation gives the temperature in Bangor as 20 degrees.

To write an equation to determine the temperature in Bangor, let's assume the temperature in Bangor is represented by the variable 'x'. The temperature in Miami is 22 degrees warmer than three times the temperature in Bangor. So, we can write the equation as follows:

3x + 22 = 82

Now, to find the temperature in Bangor, we need to solve for 'x'. We can do this by subtracting 22 from both sides:

3x = 82 - 22

3x = 60

Finally, divide both sides of the equation by 3 to solve for 'x':

x = 60 ÷ 3

x = 20

Therefore, the temperature in Bangor is 20 degrees.

Final answer:

The correct equation to find the temperature in Bangor, Maine, given the temperature in Miami, Florida, is 3x + 22 = 82. After solving, the temperature in Bangor is found to be 20 degrees Fahrenheit.

Explanation:

The temperature in Miami, Florida is given as 82 degrees Fahrenheit. According to the problem statement, this temperature is 22 degrees warmer than three times the temperature in Bangor, Maine. Thus, we can express this relationship algebraically as:

Miami temperature = 3 × Bangor temperature + 22

Substituting the known Miami temperature into the equation, we have:

82 = 3 × Bangor temperature + 22

To solve for the temperature in Bangor, we need to subtract 22 from both sides of the equation:

82 - 22 = 3 × Bangor temperature

60 = 3 × Bangor temperature

Finally, divide both sides by 3 to get the temperature in Bangor:

Bangor temperature = 60 / 3

Bangor temperature = 20 degrees Fahrenheit

Therefore, the correct equation to determine the temperature in Bangor is:

3x + 22 = 82

Final answer:

To use the distributive property for the expression 5(2x - 1), multiply each term inside the parentheses by 5, resulting in the equivalent expression 10x - 5.

Explanation:

To use the distributive property to write an expression equivalent to 5(2x - 1), you simply multiply each term inside the parentheses by the factor outside, which is 5 in this case. So, you will multiply 5 by 2x and then 5 by -1.

Multiply 5 by 2x: 5 × 2x = 10x.

Multiply 5 by -1: 5 × -1 = -5.

Combine the two results to get the equivalent expression: 10x - 5.

Therefore, using the distributive property, the expression equivalent to 5(2x - 1) is 10x - 5.

The corresponding side lengths of the figure will be proportional based on the scale factor.

Step-by-step explanation:

A dilation can either be an enlargement or reduction.  If the scale factor is less than one then the figure will be a reduction.  If the scale factor is one or larger then the figure will be an enlargement.  Since a dilation is basically multiplying the figure will always be proportional to the original figure.

Answer:

y-intercept is 4.

Step-by-step explanation:

Given,

Equation of the line,

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

∵ Equation of a line is y = mx + c, where m is the slope of the line,

By comparing,

The slope of the above line is [tex]\frac{4}{3}[/tex],

Let m' is the slope of the line perpendicular to above line,

[tex]\implies m'\times \frac{4}{3}=-1[/tex]

[tex]\implies m' = -\frac{3}{4}[/tex]

Now, the equation of a line passes through a point [tex](x_1,y_1)[/tex] is,

[tex]y-y_1=m(x-x_1)[/tex]

So, the equation of the perpendicular line having slope [tex]-\frac{3}{4}[/tex] and passes through ( 4,1) is,

[tex]y-1=-\frac{3}{4}(x-4)\implies y=-\frac{3}{4}x+3+1\implies y=-\frac{3}{4}x+4[/tex]

For y-intercept,

x = 0,

⇒ y = 4

Hence, the y-intercept of the perpendicular line is 4.

Answer:

θ = 240

and

cos(θ) = -0.5

Step-by-step explanation:

Theta is in the third quadrant, that meansit goes from 180 to 270 degrees

Then,

cos^2 (θ) =1/4

cos (θ) = ± 1/2

θ = arccos(0.5)

θ = 60

But in the third quadrant

θ = 180 + 60  = 240

θ = 240

and

cos(θ) = -0.5
