Answer:

$x = 14$

Step-by-step explanation:

$\cos( \theta) = \frac{a}{h} \\ \cos(59) = \frac{x}{28} \\ 0.5 \times 28 = x \\ 14 = x$

We know

$\boxed{\sf cos\theta=\dfrac{Base}{Hypotenuse}}$

$\\ \sf\longmapsto cos59=\dfrac{x}{28}$

$\\ \sf\longmapsto 0.5=\dfrac{x}{28}$

$\\ \sf\longmapsto x=28\times 0.5$

$\\ \sf\longmapsto x\approx 14$

Given two dice, what is the probability of rolling a four on the second die, given that you already rolled a four on the first d

Sholpan [36]

Answer: 1/6

Reason:

There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.

The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.

The functions f(x) and g(x) are shown on the graph.<br> Rx) = x²<br> What is g(x)?

djyliett [7]

It’s a flip of the graph on the x-axis

Therefore f(x) = - x^2 (NOT IN PARENTHESIS that would be a reflection on the y axis)

It’s a shift 4 y values down therefore

g(x) = - x^2 - 4

An Arithmetic series has 20 terms. The first term is -81. The sum of all the terms is -480. Use the arithmetic sum formula to fi

timama [110]

Answer:

The last term is 33.

Step-by-step explanation:

Sn = (n/2)(a1 + L) where a1 = first term and L = the last.

So:

-480 = (20/2) ( -81 + L)

-480 = 10( L - 81)

L- 81 = -480 / 10 = -48
