Someone plz help.The temperature started at 35°F. If the temperature went down 4°F and then up 2°F, whats is the temperature dif

timama [110]

Answer:

The temperature difference relative to the high temperature is -2°F.

Step-by-step explanation:

We are given that the temperature started at 35°F. The temperature went down 4°F and then up 2°F.

Firstly, the original temperature = 35°F

Now, it is stated that the temperature went down 4°F, this means that the temperature decreases by this amount.

So, the new temperature = 35°F - 4°F = 31°F

Now, the temperature went up by 2°F, this means that the temperature increases by this amount.

So, the final temperature = 31°F + 2°F = 33°F

Now, the final temperature difference relative to the high temperature is given by = 33°F - 35°F = -2°F.

{Here, the maximum temperature is 35°F}

I don’t understand how to find the height

ANTONII [103]

Answer:

height, x is 235 ft

Step-by-step explanation:

From trigonometric ratios:

$\cos( \theta) = \frac{adjacent}{hypotenuse}$

but:

$\theta = 90 \degree - 36 \degree \\ \theta = 54 \degree$

adjacent is x

hypotenuse is 400 ft

$\ \cos ( 54 \degree) = \frac{x}{400} \\ \\ x = 400 \ \cos (54 \degree) \\ x = 235 \: \: feet$

What is the inverse of the function f(x)= 2x+1

Sergeu [11.5K]

In order to invert a function, switch y and x in the definition, and solve for y again:

$y=2x+1 \mapsto x=2y+1$

Solving for y, we have

$x=2y+1\iff x-1=2y \iff y=\dfrac{x-1}{2}$

Vertex typically means a corner or a point where lines meet for an example i guess you can say squares have four corners, each is called a vertex. The plural form of vertex is vertices.
