Answer:

The required integer is -15.

Step-by-step explanation:

Given,

The temperature dropped 3°c every hour,

So, the change in temperature every hour = -3°C

Total number of hours for which the temperature were changed = 5,

Thus, the total change in temperature = change for an hour × total number of hours,

= -3° × 5

= -15°

Hence, the integer that represents the change in temperature is -15.

Workout the value of the largest angle
Elanso [62]

Step-by-step explanation:

These angles all add up to 360° because they form a circle, so b + b + 2b + 5b = 360°, and b = 40°. The largest angle is 5b which is 5 * 40 = 200°.

What are the remaining trig functions? and how do i solve for them? pls help
erastovalidia [21]

You're told that tan(<em>θ</em>) is positive, but

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)

and you're also told that sec(<em>θ</em>) = 1/cos(<em>θ</em>) = -3. So if cos(<em>θ</em>) is negative, sin(<em>θ</em>) must also be negative. In turn, both sec(<em>θ</em>) = 1/cos(<em>θ</em>) and csc(<em>θ</em>) = 1/sin(<em>θ</em>) are also negative.

Now, recall the Pythagorean identity,

cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1

Multiply through both sides by 1/cos²(<em>θ</em>) to get an alternate form of the identity,

1 + tan²(<em>θ</em>) = sec²(<em>θ</em>)

Solve for tan(<em>θ</em>) (which we know is positive):

tan(<em>θ</em>) = √(sec²(<em>θ</em>) - 1) = 2√2

Right away, we get

cot(<em>θ</em>) = 1/tan²(<em>θ</em>) = 1/(2√2) = √2/4

Since sec(<em>θ</em>) = -3, it follows that cos(<em>θ</em>) = -1/3.

Then

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)   ==>   sin(<em>θ</em>) = 2√2 × (-1/3) = -2√2/3

and so

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -3/(2√2)

What is the rang y=-x2 - 2x + 3?​
Damm [24]

This is a downward facing parabola, so its range comes in the form

(-\infty, m) where m is the y coordinate of the vertex of the parabola.

We can find the x coordinate of the vertex using

x=-\dfrac{b}{2a}=-\dfrac{-2}{-2}=-1

And if we plug -1 in the equation we get the y coordinate of the vertex:

y=-(-1)^2-2(-1)+3 = -1+2+3=4

So, the range is the interval

(-\infty, 4)
