i really need help with my homework and its so hard can you help me plss here is question one m+43=38+46

Answer:

4x10=40

It will lose 40% pressure after four minutes

It will lose 40% pressure after four minutes

Consider the function:

[tex]y = a(1\pm r)^m[/tex]

where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

We have been given that a bike tire just ran over a nail, and it is losing pressure at a rate of 10% every minute. The tire pressure is currently 1,060 kilo-pascals. We are asked to find the tire pressure in 4 minutes.

We will use exponential decay formula to solve our given problem.

[tex]y = a(1\pm r)^m[/tex]

Let us convert 10% into decimal.

0.01

Initial value is 1,060 . Upon substituting our given values in above formula, we will get:

y = 1,060 (1 - 0.01)^4

Therefore, the tire pressure will be approximately 40% kilo-pascals in 4 minutes.

Answer:

The distance between -1,12 and -1,-3 is 15

Step-by-step explanation:

Simplify-

Multiply −1 by −1.

√(−1+1)^2 + ((−3) −12)^2

Add −1 and 1.

√0^2 + ((−3) −12)^2

Raising 0 to any positive power yields 0.

√0 + ((−3) −12)^2

Subtract 12 from −3.

√0 + (−15)^2

Raise −15 to the power of 2.

√0 + 225

Add 0 and 225.

√225

Rewrite 225 as 15^2.

√15^2

Pull terms out from under the radical, assuming positive real numbers.

Answer:

D

Step-by-step explanation:

First of, let's make a table for y = cos(x)

(x , y): (0 , 1) (π/2 , 0) (π , -1) (3π/2 , 0) (2π , 1)

Now, making a table for y = 2cos(x) is simple. We just have to multiply all the y-values from the previous table by 2.

(x , y): (0 , 2) (π/2 , 0) (π , -2) (3π/2 , 0) (2π , 2)

Graphing these coordinates, we find that the answer is D.

Answer:

x = 5, x = 7

Step-by-step explanation:

tangents from an external point to a circle are congruent , then

x² = 12x - 35 ( subtract 12x - 35 from both sides )

x² - 12x + 35 = 0

(x - 5)(x - 7) = 0

equate each factor to zero  and solve for x

x - 5 = 0 ⇒ x = 5

x - 7 = 0 ⇒ x = 7

Hello.

There are really 2 ways to think about the given problem.

First, we can use the slope formula:

[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex]

[tex]\displaystyle\frac{-6-(-2)}{-9-(-9)} =\frac{-6+2}{-9+9} =\frac{-4}{0} =[/tex]

Slope = undefined

The second way is to just take a look at the points.

You should notice that the x-coordinates are the same.'

If the x-coordinates are the same, then the slope is

9/9

= 9 ÷ 9

= 1

4/3 > 9/9

Thus, your answer: YES 4/3 is GREATER THAN 9/9

Good luck on your assignment & enjoy your day!

Answer:

2x^2+7x and 8y+3x

Step-by-step explanation:

Okay for the first one when you combine like terms you are adding the ones with the same terms so the ones that have X in it you add, the one with Y you add so it would be

2x+6x=8x ----> 8x-5x=3x

5y+3y=8y so

8y+3x

same thing for the other one so the answer is:

2x^2+7x

Answer:

Range => y ≤ -2

Domain => All real numbers

Step-by-step explanation:

As it extends horizontally either way, domain can be any possible value.

Whereas it only extends from -2 towards the bottom, therefore the range will be less than or equal to -2.

The shot was blocked between 0.84 and 0.85 seconds after the shot is launched.

The given equation for ball height

[tex]=6+30t-16t^{2}[/tex]

The equation for the blocker's height will be

[tex]=9+25t-16t^{2}[/tex]

But, the shot is made before two-tenths of a second or 0.2 seconds therefore modified equation for ball height is

[tex]=6+30(t-0.2)-16(t-0.2)^{2}[/tex]

Now for the shot to be blocked, the height of the shot-blocker must be greater than the height of the ball which is shot before 0.2 seconds :

[tex]9+25t-16t^{2} \geq 6+30(t-0.2)-16(t-0.2)^{2}[/tex]

[tex]9+25t-16t^{2} \geq6+30t-6-16(t^{2} -0.4t+0.04)[/tex]

[tex]9+25t-16t^{2} \geq30t-16t^{2} -6.4t+0.64[/tex]

[tex]9+25t\geq36.4t-0.64[/tex]

[tex]9.64\geq11.4t[/tex]

[tex]t \leq \dfrac{9.64}{11.4}=0.846[/tex]

Thus the shot was blocked between 0.84 and 0.85 seconds after the shot is launched.
