Answer:

Step-by-step explanation:

6z⁶ - 21z⁴ - 12z² = 2*3*z⁶ - 3*7*z⁴ - 4*3*z²

= 3z² (2z⁴ - 7z² - 4)

This expression cannot be simplified, as you cannot add or subtract variables raised to different exponents.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).

Phoenix [80]

Answer:

$y=20(2)^x$

Step-by-step explanation:

We want to write an exponential function that goes through the points (0, 20) and (6, 1280).

The standard exponential function is given by:

$y=ab^x$

The point (0, 20) tells us that y = 20 when x = 0. Hence:

$20=a(b)^0$

Simplify:

$20=a(1)\Rightarrow a=20$

So, our exponential function is now:

$y=20(b)^x$

Next, the point (6, 1280) tells us that y = 1280 when x = 6. Thus:

$1280=20(b)^6$

Solve for b. Divide both sides by 20:

$64=b^6$

Therefore:

$b=\sqrt[6]{64}=2$

Hence, our function is:

$y=20(2)^x$

Determine the relationship between the two triangles and whether or not they

Ira Lisetskai [31]

Answer: These ARE congruent to each other.

Step-by-step explanation: Do you see the ''tick marks?'' They both have 1 set of 2, and 1 set of 1. If that makes sense. They also have a "angle" in one of their acute angles.

1. Find the common difference and find the 75th term of the arithmetic sequence: 3, 6, 9, 12, ....

Ymorist [56]

Answer:

$\boxed{225}$

Step-by-step explanation:

Arithmetic sequence

$Un = a + (n - 1)b$

First step, find its difference

$b = U_2 - U_1$

$b = 6 - 3$

$b = 3$

So, we get

$a = 3$

$b = 3$

Finally, Let's find the 75th term

$U_{75} = 3 + (75 - 1)3$

$U_{75} = 3 + (74)3$

$U_{75} = 3 + 222$

$U_{75} = 225$
