Answer:

70 degrees

Step-by-step explanation:

If cosm<A = 342/1000, we are to find the value of a

Take arccos of both sides

cosm<A = 342/1000

cosm<A = .342

arccos(cosm<A) = arccos(0.342)

m<A = arccos(0.342)

m<A = 70 degrees

Hence the measure of m<A is 70 degrees

Explanation:

If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.

Answer:

Part A: 8

Part B: $1

Step-by-step explanation:

Part A:    We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.

Divide both sides by 3 to get 1 bushel=$8.

We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.

The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.

Part B:  In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1

Therefore, the price has increased by $1 this year.

Answer: (-2, 10)

Explanation: Since one equation has a +4y and the other equation has

a -4y, when we add the equations together, the y's will cancel out.

So we have 23x = -46 and x = -2.

To find y, plug -2 back in for x in either of the two original equations.

I've chosen to plug -2 into the first equation to get 10(-2) + 4y = 20.

Solving from here, y = 10.

So our final answer is the ordered pair (-2, 10).

Now, check your answer.

PR =28,6

Step-by-step explanation:

[tex] {pr}^{2} = {18}^{2} + {27}^{2} - 2 \times 18 \times 27 \cos(76) = 817.85 \\ pr = 28.6 \\ \cos(p) = \frac{ {18}^{2} + {28.6}^{2} - { {27}^{2} } }{2 \times 18 \times 28.6 } = 0.4 \\ m < p = 66.42 \\ m < r = 180 - 76 - 66.42 = 37.58[/tex]

Answer:

x = 8

Step-by-step explanation:

-4x + 6(6 - 2x) = -7x - 36

-4x + 36 - 12x = -7x - 36

-16x + 36 = -7x - 36

      +36           +36

-16x + 72 = -7x

+16x           +16x

72 = 9x

divide by 9

x = 8

Answer:

-121 feet

Step-by-step explanation:

If itś 121 feet below sea level than it would be -121 feet

The signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.

To represent the elevation of a point in a valley that is 121 feet below sea level as a signed number, we can use a negative sign (-) to indicate a position below sea level.

Therefore, the signed number to represent this elevation would be -121. The negative sign (-) indicates that the elevation is below sea level, and the magnitude of the number (121) represents the distance below sea level, which is 121 feet in this case.

In summary, the signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.

Answer:

Step-by-step explanation:

The slope of a line passing through two given points:   [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(1, -5)   ⇒  x₁ = 1  ,   y₁ = -5

(-5, -6)   ⇒  x₂ = -5  ,   y₂ = -6

[tex]m=\dfrac{-6+5}{-5-1}=\dfrac{-1}{-6}=\dfrac16[/tex]

Point-slope form of equation of a line with givem slope m and passing through point (x₁, y₁):   [tex]y-y_1=m(x-x_1)[/tex]

(1, -5)   ⇒  x₁ = 1  ,   y₁ = -5

Therefore:

                [tex]y-(-5)=\frac16(x-1)\\\\\underline{y+5=\frac16(x-1)}[/tex]
