what is 18 mm in cm's

Answer:

[tex]\cos^{-1}(\frac{6.3}{9.8})[/tex]

[tex]\sin^{-1}(\frac{7.5}{9.8})[/tex]

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The sine ratio is the length of the opposite side expressed over the hypotenuse.

[tex]\sin m\angle ABC=\frac{7.5}{9.8}[/tex]

Take the sine inverse of both sides to get;

[tex]m\angle ABC=\sin^{-1}(\frac{7.5}{9.8})[/tex]

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

[tex]\cos m\angle ABC=\frac{6.3}{9.8}[/tex]

Take the cosine inverse of both sides to get;

[tex]m\angle ABC=\cos^{-1}(\frac{6.3}{9.8})[/tex]

Answer:

Option: B is the correct answer.      

B)     Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

                    [tex]y=3.4(0.66)^x[/tex]

We know that any exponential function of the type:

                                [tex]y=ab^x[/tex]

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have:  [tex]y=3.4\times (0.66)^0\\\\\\y=3.4[/tex]

Hence, the y-intercept is:   3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

    ⇒ 0.66=1-r

   ⇒   r=1-0.66

    ⇒ r=0.34

Hence, the rate is: 34%

          option: B is the correct answer.

Answer:

314 cm²

Step-by-step explanation:

It's not the point O, but the circle O, a point has no area.

The area of a circle is given by the formula A = π r²

We don't have r (radius), but we have the diameter, which is double the radius.  So, r = d / 2 = 20 cm / 2 = 10 cm

Now, we can plug r directly into the equation:

A = π r² = π 10² = 100π = 314 cm²

[tex]\frac{5}{2s}-\frac{9}{4s}=-\frac{3}{4}[/tex]

[tex]\frac{10-9}{4s}=-\frac{3}{4}[/tex]

[tex]\frac{1}{4s}=-\frac{3}{4}[/tex]

[tex]s=-\frac{1}{3}=-0.33[/tex]

Answer:

[tex]A=(2x^{2}+9x-18)\ m^{2}[/tex]

Step-by-step explanation:

Let

L-----> the length of the concert hall

W----> the width of the concert hall

we know that

The area of a rectangle ( concert hall) is equal to

[tex]A=LW[/tex]

we have

[tex]L=(x+6)\ m[/tex]

[tex]W=(2x-3)\ m[/tex]

substitute the values

[tex]A=(x+6)(2x-3)\\ \\A=2x^{2} -3x+12x-18\\ \\A=(2x^{2}+9x-18)\ m^{2}[/tex]

The area of the concert hall's floor, in square meters, is represented by the simplified algebraic expression 2x² + 9x - 18, which is derived by multiplying the hall's length (x + 6) by its width (2x - 3) then simplifying the resulting expression.

The area of a rectangle is calculated by multiplying the length by the width. In this case, the length of the concert hall is given as (x + 6) meters and the width as (2x - 3) meters. Therefore, the area of the concert hall's floor, expressed in square meters, is the product of these two expressions.

So, you multiply (x + 6) by (2x - 3) to get the area, which gives you the following expression: 2x² - 3x + 12x - 18. Now, simplify this expression by combining like terms.

The simplified expression for the area of the floor in square meters is then 2x² + 9x - 18.

[tex]f(x)=|x+4|+2[/tex]

Step-by-step explanation:

The given absolute value function is

[tex]f(x)=|x|[/tex]

This is the base or the parent function.

The transformation [tex]f(x)=|x+b|+c[/tex] will shift the parent function b units to the left and c units up.

From the question, b=4 units and c=2 units.

The new equation is [tex]f(x)=|x+4|+2[/tex]

Answer:  The equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Step-by-step explanation:  We are given to find the equation of the new function if we apply the following changes to the absolute value parent function f(x)=lxl :

Shift 4 units left   and  Shift 2 units up.

We know that

if we shift the absolute value parent function f(x) = |x| to h units left and k units up, then the new equation will be

[tex]f(x)=|x+h|+k.[/tex]

Therefore, if the function is shifted 4 units left and 2 units up, then the equation of the new function will be

[tex]f(x)=|x+4|+2.[/tex]

Thus, the equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Answer:

7+24i

Step-by-step explanation:

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y. In other words, the two binomials are conjugates of each other.

The conjugate of a complex number is obtained by negating its imaginary part while keeping the real part unchanged. So, for 7 - 24i, the conjugate is 7 + 24i. The real part remains 7, and the imaginary part changes from -24i to +24i.

In the field of mathematics, specifically complex numbers, the conjugate of a complex number is formed by changing the sign of its imaginary part. Given the complex number 7 - 24i, its conjugate is obtained by changing the sign of the imaginary part (-24i) to a positive. So, the conjugate of 7 - 24i is 7 + 24i.

Step-by-step explanation:

it is an obtuse angle

The answer is:

The missing angle "x" is equal to 130°.

We need to remember that the sum of all of the angles of any polygon will be all equal to 360°.

So, we are given the following exterior angles:

[tex]140\°\\34\°\\56\°\\[/tex]

Now, if the sum of all the exterior angles is equal to 360°, we can use it to calculate "x", so:

[tex]360\°=140\°+34\°+56\°+x\\\\x=360\°-(140\°+34\°+56\°)=360\°-230\°\\\\x=130\°[/tex]

Hence, the missing angle "x" is equal to 130°.

Answer:

Kyle purchased 12 pencils

Step-by-step explanation:

p= pencils

1.24p - 5.12 = 20

or, you can do this back wards like this....

20 - 5.12 = 14.88

14.88 / 1.24 = 12

p=12

(sorry for any confusion, this is just how my brain works...)

Kyle bought 12 pencils at $1.24 each. This determination is based on subtracting the amount of change he received from his $20 payment and dividing by the cost per pencil.

Kyle bought x pencils for $1.24 each, paid with a $20 bill, and received $5.12 in change. Therefore, the total amount he spent can be calculated by subtracting the change from the total payment ($20 - $5.12 = $14.88). As he spent this amount on pencils that cost $1.24 each, the number of pencils he bought can be determined by dividing the total spent by the cost per item ($14.88 / $1.24). Therefore, Kyle bought approximately 12 pencils (the exact result is 12.003, but as pencils cannot be fractional, we round down to the nearest whole number).

Answer:

d. 40 pounds

Step-by-step explanation:

We know both weights of the astronaut, and we know one of the weight of the rock... we need to find the other weight of the rock (on Earth).

The easiest way to deal with those problems is to use a cross-multiplication.

We'll place on top the weights on Earth and as denominators the weights on Mars:

[tex]\frac{x}{16} = \frac{180}{72}[/tex]

So we isolate x = (16 * 180) / 72 = 2,880 / 72 = 40 pounds.

The rock then weights 40 pounds on Earth.

Answer:

You can find the point of intersection of the line with the y-axis and the  the point of intersection of the line with the x-axis. See the graph attached.

Step-by-step explanation:

Find the intersection with the y-axis. Substitute [tex]x=0[/tex] into the equation and solve for y:

[tex]y-3=\frac{1}{3}(x+1)\\\\y-3=\frac{1}{3}(0+1)\\\\y-3=\frac{1}{3}(1)\\y=\frac{1}{3}+3\\\\y=\frac{10}{3}[/tex]

[tex]y[/tex]≈3.33

Find the intersection with the x-axis. Substitute [tex]y=0[/tex] into the equation and solve for x:

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

[tex]0-3=\frac{1}{3}(x+1)\\(-3)(3)=x+1\\-9-1=x\\x=-10[/tex]

Now, you know that the line passes through the point (0,3.33) and (-10,0). Now you can graph the function. (Observe the graph attached)
