Answer:

135 cm

Step-by-step explanation:

[tex] \cos(43) = \frac{75}{y} [/tex]

[tex]y = \frac{75}{ \cos(43) } [/tex]

[tex]y = 135[/tex]

Answer:

y ≈ 102 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos43° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{75}{y}[/tex] ( multiply both sides by y )

y × cos43° = 75 ( divide both sides by cos43° )

y = [tex]\frac{75}{cos43}[/tex] ≈ 102 cm ( to 3 sf )

Step-by-step explanation:

The initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.

Answer:

y=-6/10x+17/11

Step-by-step explanation:

1-5 keep it, change it, flip it. -6

12-2= 10

y=-6/10x+b

you can take one of the coordinates

I used (2,5) in the equation.

y is 5

m is -6/10

x is 2

-6/10x2 is -12/10

remember to drop down 5

5= -12/10+b

look for fluffy cloud -12/10 turn it to a positive and add it to five and the answer is 17/11 equals b.

The rate is the plane gaining altitude (y) is 300 m/sec and The horizontal component (x) of velocity for the plane is 400 m/sec.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

An experimental plane just after takeoff climbs with a speed of 500 km/h at an angle of 37 degrees with the horizontal.

A.  The rate is the plane gaining altitude (y) will be

[tex]\rm y = v * sin \theta\\\\y = 500 *sin 37\\\\y = 300 \ m/sec[/tex]

The rate is the plane gaining altitude (y) is 300 m/sec

B.  The horizontal component (x) of velocity for the plane will be

[tex]\rm x = v * cos \theta\\\\x= 500 *cos 37\\\\x = 400 \ m/sec[/tex]

The horizontal component (x) of velocity for the plane is 400 m/sec.

The distance of Saturn from the Sun by the orbital period formula is 9.54732 astronomical units

Orbital period is the time period, which is required for a planet or one astronomical body to revolve completely around the other body.

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula

[tex]P =a^{3/2}[/tex]

The orbital period of Saturn is 29. 5 years. To find the value of distance of Saturn from the Sun, put the values in the above formula as,

[tex]29.5=a^{3/2}\\a=29.5^{3/2}\\a=9.54732\rm[/tex]

Thus, the distance of Saturn from the Sun by the orbital period formula is 9.54732 astronomical units.

Answer:

7,912.8 inch³ of aluminum is needed to make 70 metal balls

Step-by-step explanation:

r = 3 inches and π = 3.14

single aluminum ball, 113.04 inch³ of aluminum

113.04 inch³ of aluminum is used for 1 ball, then we multiply 70 with this value to determine the aluminum needed for 70 such balls.

The table on the left is arithmetic

This is because each term is increasing by the same amount (2) each time.

--------------------------------------------

The table on the right is geometric

Why? Because this time we are multiplying each term by the same value (2) to get the next term.

Both involve the number 2, but the first table uses addition while the second table uses multiplication.

1) Arithmetic

~3,5,7

common difference of 2

2)Geometric

~3,6,12

each term is found by multiplying the previous one by a fixed number

Answer:

YELLOW

Step-by-step explanation:

Just always keep this tip in mind:

A negative times a positive is a negative, and a negative times another negative cancels out to become a positive.

If there is an odd number of negatives multiplied together, the outcome will always be negative.

The range of the given function is [-2,∞).

the range is the complete set of all possible values of the dependent variable say 'y'.

given function is:  f(x)=  |x – 12| – 2

f(x) = x-14  ∀ x≥12

f(x) = -x+10 ∀ x < 12

value of the above function at x=12 will be -2 means the minimum value of the function will be -2.

now, from the graph, we can see that f(x) is leading to infinity

so the range will be [-2,∞).

therefore, The range of the given function is [-2,∞).

to get more about range, refer to the link,

The range of the function is all real number of input value (y-value) grater than or equal to -2.

Range of a function is the set of all the possible output values which are valid for that function.

The function given in the problem is,

[tex]g(x) = |x - 12| - 2[/tex]

Lets, compare the above function with the vertex form of the absolute function. The vertex form of the absolute function with vertex (h, k) can be given as,

[tex]y=a|x-h|+k[/tex]

On comparing the vertex form with the given equation, we get,

[tex]h=12\\k=-2[/tex]

Now, as the tange of a function is the set of all the possible output values which are valid for that function.

Here, the function does not take the value which are less than -2. Hence, the range of the function is all real number of input value (y-value) grater than or equal to -2.
