How many terms can 5x+9-4b have

Mathematics
1 answer:
Nikolay [14]3 years ago
4 0

Answer:

8x

Step-by-step explanation:

The constants are the numbers that are NOT

attached to anything. In the expression, 3x + 2,

(2) is a constant because it is not attached to

anything. The (3) is not a constant because it

is attached to x, and it is actually a coefficient.

Remember that the general formula for a circle is <span> 
(x – h)</span>² + (y – k)² = r²<span>, where (h,k) is the coordinate of the center. 
We already know that (h,k) = (5,-4), since we know the center's coordinates. We need to find r, the radius, using the distance between the center and the point (-3,2). 
To do this, we can either use the distance formula, or plug in the points in our circle equation and solve for r.
Let's do the second one, plugging in and solving for r.
We can use the point (-3,2) for (x,y):
</span>(x – h)² + (y – k)² = r²
(-3 - 5)² + (2 - -4)² = r²
(-8)² +(6)² = r²
64 + 36 = r²
100 = r²
r = 10
We know that r=10, and that r² = 100
Using h, k, and r, we can now solve for the equation of the circle in standard form.
The equation of the circle is:
(x – 5)² + (y + 4)² = 100

Arnold skydives out of an airplane with a parachute. After he opened his parachute Arnold descended at 70feet per second. An obs
vivado [14]

Answer:

Arnold descended a distance of 5,250 ft after his parachute opened

Step-by-step explanation:

Here in this question, we want to know the distance Arnold descended after his parachute opened.

Mathematically, we know that distance = speed * time

In this case;

The speed is the rate at which he descended = 70 ft per second

Now the time is 1 minute and 15 seconds; since 1 minute is 60 seconds, then 1 minute and 15 seconds is 60 + 15 = 75 seconds

So what we are saying is he descended at a rate of 70 ft per second for 75 seconds

Thus, his distance of descent will be 70 ft per second * 75 seconds = 5,250 ft

A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?
alexira [117]

Answer:

Right, I am an idiot so i might be wrong

Step-by-step explanation:

Every triangle has three angles which sum to 180 degrees.

There are three types of triangles based on the measures of its angles.

Right Triangle - Has one 90 degree angle

Acute Triangle - All angles less than 90 degrees

Obtuse Triangle - One angle greater than 90 degrees

In this example we are given 2 angles and must find the measure of the 3rd.

a + 56 + 34 = 180

a + 90 = 180

a = 90

Therefore, it is a Right Triangle.
