Find five consecutive integers whose sum is 195.

Elodia [21]

X + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 195

(Make sure you don't add "x+5" because "x + 0" is an included term.)

5x + 10 = 195
5x = 185
x = 37

Hope this helps!

What is the minimum y-value after which the exponential function will always be greater than the linear function? y = 1 y = 3 y

Stells [14]

Answer:

y = 4.

Step-by-step explanation:

I suppose that this question relates to the image that can be seen below.

In the image, the green line represents the exponential function and the blue line represents the linear function.

The y-value after which the exponential function will always be greater than the linear function is the y-value where bot graphs intersect, such that after that point, the blue line starts increasing fast, and is always above the green line.

In this case, this point is the second intersection, and we can see that this intersection happens in the point (2, 4)

Remember that the usual notation for points is (x, y).

Then the y-value after which the exponential function will always be greater than the linear function is y = 4.

Im not sure how to do this or what function to use SIN, COS, or TAN but if you could walk me through it that would be so so so a

Elanso [62]

Answer: 3.8

Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.

sin (of given angle)= opposite / hypotenuse.

Sin (70 degrees) = ? / 4

Then you solve for “?”

Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8
