Answer:
-7
Step-by-step explanation:
It is helpful to recognize 128 = 2^7. Then you know ...
[tex]\log_2\dfrac{1}{128}=\log_2{2^{-7}} =\boxed{-7}[/tex]
__
If you don't know that, you can use the change of base formula:
[tex]\log_2{\dfrac{1}{128}}=\dfrac{\log{\dfrac{1}{128}}}{\log{2}}=\dfrac{-2.1072}{0.30103}=\boxed{-7}[/tex]
Give the value of each trigonometric ratio.
cos m
cos n
sin m
sin n
tan m
tan n
Step-by-step explanation:
Cos m = 35/37 = 0.94
Cos n = 12/37 = 0.32
Sin m = 12/37 = 0.32
Sin n = 35/37 = 0.94
tan m = 12/35 = 0.34
tan n = 35/12 = 2.91

Solve the system by substitution.
y = 8x – 6
y = 2x
Answer:
x = 1
y = 2
Step-by-step explanation:
y =8x - 6 ---------------------------------(I)
y = 2x -------------------------------------(II)
substitute y = 2x in equation (I)
2x = 8x - 6
Add 6 to both sides
2x + 6 = 8x
Subtract 2x from both sides
6 = 8x - 2x
6 = 6x
Divide both sides by 6
6/6 = x
x = 1
Substitute x = 1 in equation (II)
y = 2*1
y = 2

Answer:
Surface area of net = 310 cm²
Step-by-step explanation:
Given:
Dimension of two same rectangle = 11 cm by 9 cm
Dimension of single rectangle = 11 cm by 7 cm
Height of two triangle = 5 Cm
Base of two triangle = 7 Cm
Find;
Surface area of net
Computation:
Surface area of net = Surface area of two same rectangle + Surface area of single rectangle + Surface area of two same triangle
Surface area of net = 2[l x b] + [l x b] + 2[(1/2)(b)(h)]
Surface area of net = 2[11 x 9] + [11 x 7] + 2[(1/2)(7)(5)]
Surface area of net = 198 + 77 + 35
Surface area of net = 310 cm²

Rolando imported 138 boxes of mangoes.
There were 24 mangoes in each box.
He reserved 72 mangoes for his friends and sold the rest to 3
customers.
If each customer bought an equal number of mangoes, how
many mangoes did each customer buy?
Answer:
Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.
Step-by-step explanation:
1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )
2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.
3. 45 x 24 ( The amount of mangoes in each box ) = 1080
4. 45 boxes/1080 mangoes per customer.
To recheck:
1080 x 3 ( The amount of customers again ) = 3240.
135 x 24 ( The amount of mangoes per box ) = 3240.
I Hope this helped! :)
How do I solve this finding the first four of the sequence?
Answer:
Step-by-step explanation:
a(1) = -7 (given)
a(2) = a(1) + 4 = -7 + 4 = -3
a(3) = a(2) + 4 = -3 + 4 = 1
a(4) = a(3) + 4 = 1 + 4 = 5

True or False? When an exponential function decreases, it is called exponential growth.
Answer:
When we know the initial population
, the next thing we need to solve the growth constant
to derive the exponential growth function.
If the problem gives the time it takes for the population to double or the doubling time
τ
. We can find the growth constant by substituting the doubling constant into the equation and solving for t.
This means that the statement is TRUE because the term for initial population cancels out when solving for k and the doubling time is given.

Bananas cost 0.59 per pound. Create an equation that could be used to find the total cost of y of x bananas
Answer:
y = 0.59x
Step-by-step explanation:
Cost per pound of banana = $0.59
If Number of banana's = x
Total Cost of an item = price per item * number of items
Therefore,
Total cost, y = price per pound of banana * number of bananas
y = 0.59 * x
y = 0.59x

Sam's Saddles is having a sale on cowboy hats. The hats are being sold for
a 30% discount. The expression below can be used to determine the cost
of a hat on sale (h). h -0.3h Which expression could also be used to determine the cost of a hat on sale?
0.30h
0.70h
1.30h
1.70h
Answer: 0.70h
Step-by-step explanation:
The hat is being sold at a 30% discount. The expression that shows this will be:
Price = h - 0.3h
When the 0.3h is subtracted from h, we have:
= 0.7h
Another way to get to that expression:
Hat is being sold at 30% discount which means that 30% has been removed from the value leaving:
= 100% - 30%
= 70%
Price is now 70% * Normal price which is denoted as h.
= 70% * h = 0.7h

combine like terms:
27x + 18 = 180
subtract 17 from both sides of the equation:
27x = 162
divide both sides by 27:
x = 6
