Answer: the answer is: 5.6d+2.1 thats the final answer to that question.

Step-by-step explanation:

this is how you would combine like terms; you would match whatever #'s or letters together that is how you combine like terms.

for this one you would do it like this... 2.8d+2.8d-3.4-1.3 (this is how you would combine them) to solve it you would add 2.8d and 2.8d and would minus 3.4 and 1.3. i didn't solve it yet for you. if you would like me to solve it, let me know. but i explained it to you already on how to solve it.

hope that helps!

A halloween assorted bag of candy contains 4 Snickers, 2 packages of M&M's, & 3 Butterfingers. What is the probability o

a_sh-v [17]

Answer:

2/27

Step-by-step explanation:

In the question we have:

4 snickers

2 packages of M&M's

3 Butterfingers.

Total number of candies in the Halloween bag = 9

Probability of selecting some M&M's and putting them back = 2/9

Probability of selecting a Butter finger = 3/9

Therefore, the probability of selecting some M&M's, putting them back, and then selecting a Butterfinger =

Probability of selecting some M&M's and putting them back × Probability of selecting a Butter finger

2/9 × 3/9

= 6/ 81

= 2/27

What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

<u>Planck relation</u>

$\large\boxed{E = hf}$

where:

E = Energy of the photon (J).
h = Planck's constant (J · s).
f = frequency of light produced (Hz).

Given values:

E = 3.4 × 10⁻¹⁹ J
h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

$\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f$

$\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}$

$\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}$

$\implies f=0.5131\times 10^{(-19-(-34))}$

$\implies f=0.5131 \times 10^{15}$

$\implies f=5.131 \times 10^{14}$

How does the sketch of a graph of function help describe its behavior

Gwar [14]

Answer:

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

Explain the effect of C on the graph of Y=f(x) for the function y=f(x+c)

irga5000 [103]

f(x) + c -> up by c

f(x) - c -> down by c

f(x + c) -> left by c

f(x - c) -> right by c

For y = f(x + c), the y value of x now takes the y value of the function of x + c, or the one c to the right of x, shifting the entire graph left by c.
