Step-by-step explanation:

− 1 − 9 + ( −15) + (− 8) + 3 [B.O.D.M.A.S rule]

= − 1 − 9 −15 − 8 + 3

= 3 - 1 - 9 - 15 - 8 (First and last subtraction)

= 3 - 33

= -30(Ans)

Answer:

-30

Step-by-step explanation:

Well we don't necessarily have to follow pemdas right now, because there is only addition and subtraction, and they are on the same level and they don't matter which order they are used in.

So, with that being said, let's go step by step. I could've done an easier way, but for the sake of this question, I will do it a way that is a bit longer.

So, -1-9= -10.

For the next number, if there is a + and then a () and there is a negative number in the parenthesis, forget about the + and just subtract 15.

-10-15= -25

Same for the next number. -25-8= -33

-33+3= -30

The easier method is just combining the negative numbers and adding/subtracting them and then combining the positive numbers and adding/subtracting them, and then combining both results to get your answer.

Anyways, hope this helped you! If so, please leave a rating and a thanks, and let me know if I was correct! (hopefully brainliest, but up to you) Have a great day!!

Suppose f is a function which follows this pattern, where x and h are any numbers: f(a + h) = f(a)*f(h) Which type of function i

fomenos

$f$ has to be a power function in order to satisfy the recurrence pattern $f(x + h) = f(x) \cdot f(h)$

<h3>Procedure - Determination of a function with a pattern.</h3>

In this case, we must assume a given function and check such assumption fulfill the given recurrence. Let suppose that $f(x) = a^{x}$ , by algebra we have the following property:

$f(x + h) = a^{x+h} = a^{x}\cdot a^{h}$ (1)

And by the definition given in statement, we have the following conclusion:

$f(x+h) = a^{x}\cdot a^{h} = f(x) \cdot f(h)$ (2)

Therefore, $f$ has to be a power function in order to satisfy the recurrence pattern $f(x + h) = f(x) \cdot f(h)$ . $\blacksquare$

Mount everest is 8847 m high. how many centimeters high is the mountain

nata0808 [166]

Before we answer the question we must first:
1. Assess what we have so far.
2. Know what we need to find.
3. Solve.
4. Conclude.

Step 1: What we have so far.
*Mt. Everest's height in meters (m) = 8847m

Step 2: What we need to find.
*Mt. Everest's height in centimeters (cm) = ?

Step 3: Solve.
*Centi means 100.
*1m = 100cm

Conversion process:
8847m x 100cm/1m <--- we need to multiply Mt. Everest's height to 100cm/1m first because our first agenda is to remove (m) from the value.
8847 x 100cm <--- this will be our working solution.
884,700cm <--- Answer

Step 4: Conclusion.
After successfully doing the steps above, we can now conclude that the height of Mt. Everest in centimeters is: 884,700cm

Find the altitude of the triangle. 30 degrees Hypotenuse of 14

Oxana [17]

Answer:

Approx. 12.124 units tall

Step-by-step explanation:

Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).

cos(30) = x/14

Multiply both sides by 14:

14cos(30) = x

Hope this helps :)

A bag contains 6 red marbles and 2 white marbles. A marble is selected, kept out of the bag, and then another marble is selected

Finger [1]

Answer:

11/15

Step-by-step explanation:

There are 8 marbles total. If they are being selected from twice with one missing, we could add 8 and 8 - 1 together to get the denominator for the probability.

8 + (8 - 1) = 15

We have to assume the first marble taken was red, so we will have 6 plus 6 - 1 red marbles to choose from for our numerator.

6 + (6 - 1) = 11

The probability of consecutively selecting two red marbles is 11/15.
