Answer:

14) 9.2  15) 12.9

Step-by-step explanation:

14) cos(52) = x/15

x = 15cos(52)

x = 9.2349

x = 9.2

15) cos(22) = 12/x

x = 12/cos(22)

x = 12.9424

x = 12.9

9514 1404 393

Answer:

  x = {-0.44, 1.69}

Step-by-step explanation:

Multiply by the denominator to eliminate the fraction.

  3 = x(4x -5)

  4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form

Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}[/tex]

Solutions rounded to hundredths are ...

  x = -0.44

  x = 1.69

_____

A graphing calculator can show the x-intercepts easily, so it works well to write the equation in the form

  f(x) = 0

  3/(4x -5) -x = 0

Where is it?

Step-by-step explanation:

Where is the question exactly?

Answer:

area of trapezoid==1/2 h(d1+d2)=7.5/2(10+(5+2×3+5))=97.5in²

area of semi circle=1/2 πr²=1/2 ×3.14×3²=14.13in²

area of shaded region=97.5-14.13=83.37in²

Answer:

outside shape = (10x7.5)+(2)(0.5)(7.5x3) = 97.5 in^2

circular cutout = (3.14)(3^2)(0.5) = 14.1 in^2

97.5-14.1 = 83.4 in^2

Answer:

9.9 feet per second

Step-by-step explanation:

y=9.5+0.4

y=9.9

Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,

⇒ y = 9.50x + 0.4

Hence, Marcella's average speed in feet per seconds is,

y = 9.50x + 0.4

Put x = 1;

y = 9.50 × 1 + 0.4

y = 9.50 + 0.4

y = 9.54 feet

Thus, Marcella's average speed in feet per seconds is,

⇒ y = 9.54 feet

Answer:

only Katie is right

Step-by-step explanation:

first, find the nth rule using the equation n = a + (n - 1)d

a = first term (here, it's 22)

n = the position of a term

d = the constant difference between each term (here, it's -5 since each term reduces by 5)

put these in and then simplify:

n = a + (n - 1)d

n = 22 + (n - 1)(-5)

n = 22 - 5n + 5

n = -5n + 27

this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!

Answer:

-4y=40

y=-10

x-3(-10)=17

x-30=17

x=17+30

x=47

Step-by-step explanation:

Answer:

x= 5

y= -4

Step-by-step explanation:

x= 17+3y so you substitute what you got for x in so

17 +3y +7y = -23

10y=-40

y=-4 now you put -4 in for y in the first equation

x = 17 + (3 times -4)

x = 17 - 12

Answer:

[tex]\boxed{\textsf{ Hence the percentage probability of getting a not odd is \textbf{ 50\% }.}}[/tex]

Step-by-step explanation:

Given that we roll a 6 sided dice . We need to find the probability that the outcome is not a odd number . So , when we roll a dice then the possible outcomes are ,

[tex]\sf\implies Sample\ space = \{ 1,2,3,4,5,6 \}[/tex]

And the total number of possible outcomes is 6 . That is ,

[tex]\sf\implies n(Sample \ space )= 6 [/tex]

Now the total number of non odd numbers that is even numbers is 3 ( 2 , 4 & 6) .

[tex]\sf\implies n(Outcomes_{(even)})= 3 [/tex]

Now , lets use the formula of Probability that is ,

Probability :-

[tex]\qquad\boxed{\boxed{\sf P = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes }}}[/tex]

Now put on the respective values :-

[tex]\sf\implies P( getting\ a \ not \ odd ) = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes } \\\\\sf\implies P( getting\ a \ not \ odd ) =\dfrac{3}{6} \\\\\sf\implies \boxed{\sf P( getting\ a \ not \ odd ) = \dfrac{1}{2} }[/tex]

[tex]\rule{200}2[/tex]

Expressing the probability as percentage :-

[tex]\sf\implies \% \ of \ getting \ non \ odd = Probability \times 100 \\\\\sf\implies \% \ of \ getting \ non \ odd = \dfrac{1}{2}\times 100 \\\\\sf\implies \boxed{\pink{\frak{ \% \ of \ getting \ non \ odd = 50\%}}}[/tex]

Answer:

y=2x-4

Step-by-step explanation:

To find an equation perpendicular to another one, you must find the negative inverse of the slope.

In this case, -1/2 has an inverse of -2, but because we're finding the negative inverse, the two negatives cancel out and we get 2, the slope of our perpendicular equation, which crosses the initial equation, making a right angle.
