a square has a side length of 6 inches it is enlarged and the ew side length is 18 inches what is the scale factor?

Answer:

Step-by-step explanation:

I guess it is 65 because the table said so

Trigonometric function gives the ratio of different sides of a right-angle triangle. The value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

As the value of  sin(x) is given to us, therefore, we will find the value of x firstly,

[tex]\rm Sin(x)=0.3\\\\x = Sin^{-1}\ 0.3\\\\x = 17.4576[/tex]

Therefore, the value of cos(x) can be written as,

[tex]\rm Cos(x)\\\\= Cos(17.4576)\\\\= 0.9539\approx 0.954[/tex]

We can also use the trigonometric property, therefore,

[tex]\rm (Sin\ x)^2 +(Cos\ x)^2=1\\\\0.3^2 + (Cos\ x)^2 = 1\\\\Cos(x) = \sqrt{1-0.3^2}\\\\Cos(x)=0.954[/tex]

Hence, the value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.

Step-by-step explanation:

Answer:

x = 15units

Solving steps:

QS = 16 + 9

QS = 25

Cos(QSR) = RS/QS

Cos(QSR) = x/25

Cos(RST) = ST/RS

[tex] \frac{x}{25} = \frac{9}{x} [/tex]

=> [tex]x {}^{2} = 225[/tex]

Answer: y = x - 4

Step-by-step explanation:

Slope intercept form is y = mx + b

    Given:

-2x = -8 -2x

    Add 2x and 2y to both sides of the equation:

2y = 2x - 8

    Divide both sides of the equation by 2:

y = x - 4

The value of k equivalent for the reaction expressed in scientific notation is 1.2 × 10⁻³. Then the correct option is D.

The equation in which chemically react with each other is called chemical reaction and if this reaction is shown mathematically then it is called a chemical equation.

The given chemical equation will be

[tex]\rm H_2 + F_2 \xrightarrow[equil.]{at\ 600} 2HF[/tex]

[HF] = 5.82 x 10⁻² m

[H₂] = 8.4 x 10⁻³ m

[F₂] = 8.4 x 10⁻³ m

The value of k equivalent for the reaction expressed in scientific notation will be

[tex]\rm k_{eq} = \dfrac{8.4*10^{-3}*8.4*10^{-3}}{5.82*10^{-2}}\\\\k_{eq} = 1.2 *10 ^{-3}[/tex]

Answer:

part a: is c

part b: $33.25

Step-by-step explanation:

PART A: I did 6x68.45=410.70

8x39.71=317.68

3x52.25=156.75

410.7+317.68+156.75=885.13

so the closest thing to it is c

PART B: i did

5x2.89=14.45

10x9.91=79.10

48x0.36=17.28

14.45+79.10+17.28=110.83

144.08-110.83=33.25

so the case of air fresheners was $33.25

Answer: I Think It Is Greater Than Or Equal To -9

Step-by-step explanation: The given function is:

f(x)x^2+2x-8

We complete the square to write this function in the form:

f(x)=a(x-h)^2+k

We add and subtract the square of half the coefficient of x.

f(x)=x^2+2x+1^2-1^2-8

f(x)=(x=1)^2-9

The vertex of this function is (h,k) which is (-1,-9)

The equation of axis of symmetry is x=h

But h=-1, hence the axis of symmetry isx=-1

To find the x-intercepts, we put f(x)=0

(x+1)^2-9=0

(x+1)^2=9

x+1=the square root of 9

x=-4, 2

The x-intercepts are:(

-4,0) and (2,0)

The given function is a polynomial function, the domain is all real numbers

The function has a minimum value of y=-9.

Therefore the range is y|y is greater that or less than -9

Step-by-step explanation:

A. First, convert 30 minutes to a hour.

[tex] \frac{30 \: mins}{1} \times \frac{1 \: hour}{60 \: mins} = 0.5 \: hours[/tex]

[tex]4 + 0.5 = 4.5 \: hours[/tex]

Now, we can subsitue.

Part A: 1.

[tex]d(t) = 6 + 5.5 \cos( \frac{\pi}{6}(4.5) ) [/tex]

[tex]d(t) = 6 + 5.5 \cos( \frac{3\pi}{4} ) [/tex]

Part B:

[tex] \cos( \frac{3\pi}{4} ) = - \frac{ \sqrt{2} }{2} [/tex]

so

[tex]6 + 5.5( - \frac{ \sqrt{2} }{2} )[/tex]

which is approximately

2.11. feet.

Part C: The depth of the water is approximately 2.11 feet in 4.5 hours, or 4 hours and 30 minuties.

He wants to earn at least 500 so the equation has to be greater than or equal to 500:

Answer: 250 + 75x > equal to 500

Answer:

first find the slope

finding slope

y2-y1/x2-x1

-5-4/5-3

-9/2

then the slope is -9/2 or -4.5

then y=mx+b

y=-4.5x+b

then replace y=-4.5x+b

replace y by 4 and x by 3

4=-4.5times 3 +b

4=-13.5+b

b=17.5

then the equation is y=4.5x+17.5

d = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]

d = [tex]\sqrt{(-3-3)^{2} +(-8-0)^{2} }[/tex]
