Explanation:
The rule to use here is log(x)-log(y) = log(x/y)
So,
log(6)-log(3) = log(6/3) = log(2)
Answer:
log(2)
Step-by-step explanation:
As we have,
log(a)−log(b)=log(a/b)
Replace 'a' as 6 and 'b' as 3.
Then we get,
[tex]\hookrightarrow log(6)-log(3)\\\\\hookrightarrow log(\frac{6}{3} )\\\\\hookrightarrow log(2)[/tex]
A cube has a surface area of 181.5sq. In. What is the length of the sides
Answer:
Answer = 5.5
Step-by-step explanation:
The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,
181.5 = 6*s^2
Now we divide 6 by both sides to get
30.25 = s^2
Now we have to find the square root of both sides to get
5.5 = s

Answer:
D. It takes them more time to deliver packages because 157.3 x 1.25 = 196.625
Step-by-step explanation:
In the question, it states that this week it took the delivery drivers 1.25 times longer to deliver packages than last week, meaning that it took more time to deliver the packages this week than last week. With this, we can eliminate choices A and C.
Because it took them 1.25 times longer, then we can multiply 157.3 by 1.25 to find the correct sum.
157.3 × 1.25 = 196.625
The only answer choice that matches this information completely is choice D, so that is the answer.
hope this helps!

= () – 2 = 3+ – 2
How will the graph of g differ from the graph of f?
OA
The graph of g is the graph of fshifted 2 units up.
B.
The graph of g is the graph of fshifted 2 units to the left.
C.
The graph of g is the graph of fshifted 2 units to the right.
D.
The graph of g is the graph of fshifted 2 units down.
Answer:
D. The graph of g is the graph of f shifted 2 units down.
Step-by-step explanation:
Transformations
f(x) - a : vertical shift of "a" units down
f(x) + a : vertical shift of "a" units up
f(x - a) : horizontal shift of "a" units to the right
f(x + a) : horizontal shift of "a" units to the left
If g(x) = f(x) - 2
Then g(x) is f(x) shifted 2 units down.

Which mass is least 1500 mg, 13.2 kg, 30000 cg, 7428g
Answer:
1500 mg is the least mass
Step-by-step explanation:
Lets convert them all to the same mass unit,
1500 mg to grams: 1500 mg / 1000 = 1.5 grams
13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams
30000 cg to grams: 30,000 cg / 100 = 300 grams
7428g no conversion needed!
1.5 grams, 13,200 grams, 300 grams, 7,428 grams
1.5 is the smallest number

302.1 in a fraction form
Answer:
302 1/10 is our fraction form more known to be a mixed number.
Step-by-step explanation:
Fraction form from decimal is to keep our 302 and make .1 a fraction.
This is because we already have a base/whole number and just need a fraction to make this decimal an improper fraction. 0.1 is equivalent to 1/10 because in order to get to 0.1 you need to move the decimal point 1 digit to the right. You could also do 1 divided by 10.
302 1/10 is our fraction form more known to be a mixed number.

Guys, I beg you! How do you do these factoring quadratic equations!
Which is a solution to (x − 2)(x + 10) = 13
======================================================
Explanation:
There are at least three ways to solve this.
----------------------------------------------
Method 1:
We could graph y = (x-2)(x+10) using a tool like Desmos. Graph y = 13 as well which is a horizontal line.
Check out the screenshot shown below.
The parabola in red and the horizontal line in blue intersect at the locations (-11, 13) and (3, 13)
We only focus on the x coordinates of the intersection points.
Therefore, the two solutions are x = -11 and x = 3
The order of the solutions doesn't matter.
----------------------------------------------
Method 2:
Expand things out and get everything to one side
(x-2)(x+10) = 13
x^2 + 10x - 2x - 20 = 13
x^2 + 8x - 20 - 13 = 0
x^2 + 8x - 33 = 0
From here we can use the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-8\pm\sqrt{(8)^2-4(1)(-33)}}{2(1)}\\\\x = \frac{-8\pm\sqrt{64+132}}{2}\\\\x = \frac{-8\pm\sqrt{196}}{2}\\\\x = \frac{-8\pm14}{2}\\\\x = \frac{-8+14}{2} \ \text{ or } \ x = \frac{-8-14}{2}\\\\x = \frac{6}{2} \ \text{ or } \ x = \frac{-22}{2}\\\\x = 3 \ \text{ or } \ x = -11\\\\[/tex]
----------------------------------------------
Method 3:
Instead of using the quadratic formula, we could factor.
To factor x^2+8x-33, we need to find two numbers that
Multiply to -33Add to 8Through trial and error, you should get 11 and -3
11 times -3 = -3311 plus -3 = 8So,
x^2+8x-33 = 0
(x+11)(x-3) = 0
x+11 = 0 or x-3 = 0
x = -11 or x = 3

The hcf of 182 and x is 26 and the l.c.m of 182 and x is 1092 determine the value of x
The value of x such that the hcf is 26 and the l.c.m is 1092 is 156
How to determine the value of x?The numbers are given as:
182 and x
The HCF and LCM are given as:
HCF = 26
LCM = 1092
As a general rule;
The product of LCM and HCF of x and y equals the product of x and y
So, we have:
182 * x = 26 * 1092
Divide both sides by 182
x = 156
Hence, the value of x is 156
