Answer:

16

Step-by-step explanation:22 minus 6 is 16

The final mass of the sugar crystals is 16 grams if Hugo began his science experiment with 22 grams of sugar crystals.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

Hugo began his science experiment with 22 grams of sugar crystals.

During the experiment, the change in the mass of the sugar crystals was – 6 grams.

Let x be the final mass of the sugar crystals.

The value of the x can be found using:

x = 22 - 6

x = 16 grams

Thus, the final mass of the sugar crystals is 16 grams if Hugo began his science experiment with 22 grams of sugar crystals.

Answer: -1/2 (x-4)^2 + 3

Step-by-step explanation:

Since the graphs both have the same stretch of -1/2x^2, you just need to see how much they were shifted up, down, left, or right. h(x) is shifted up 3 and right 4 of f(x) so h(x) = -1/2 (x-4)^2 + 3

Answer:

[tex]h(x)=-\dfrac12(x-4)^2+3[/tex]

Step-by-step explanation:

Given:

[tex]f(x)= - \dfrac12x^2[/tex]

From inspection of the graph, [tex]f(x)[/tex] has been translated 4 units to the right and 3 units up.

Therefore, [tex]h(x)=f(x-4)+3[/tex]

[tex]\implies h(x)=-\dfrac12(x-4)^2+3[/tex]

Answer: LMT=95

Step-by-step explanation:

combine both problems to equal 166

x+x+72+96=166

Combine like terms

2x+168=166

Subtract 168 from 166

2x=168-166

Divide

X=-2/2

X=-1

Plug in -1 for x

96-1=95

72-1=71

71+95=166

LMT=95

Given:

The rule for the sequence is

[tex]f(n)=3n^2+1[/tex]

Domain of the function is the set of whole numbers greater than 0.

To find:

The first 4 terms of the sequence defined by the given rule.

Solution:

We have,

[tex]f(n)=3n^2+1[/tex]

Domain of the function is the set of whole numbers greater than 0. So, domain for first four terms are 1, 2, 3 and 4 respectively.

For n=1,

[tex]f(1)=3(1)^2+1[/tex]

[tex]f(1)=3(1)+1[/tex]

[tex]f(1)=3+1[/tex]

[tex]f(1)=4[/tex]

For n=2,

[tex]f(2)=3(2)^2+1[/tex]

[tex]f(2)=3(4)+1[/tex]

[tex]f(2)=12+1[/tex]

[tex]f(2)=13[/tex]

For n=3,

[tex]f(3)=3(3)^2+1[/tex]

[tex]f(3)=3(9)+1[/tex]

[tex]f(3)=27+1[/tex]

[tex]f(3)=28[/tex]

For n=4,

[tex]f(4)=3(4)^2+1[/tex]

[tex]f(4)=3(16)+1[/tex]

[tex]f(4)=48+1[/tex]

[tex]f(4)=49[/tex]

Therefore, the first 4 terms of the sequence defined by the given rule are 4, 13, 28 and 49 respectively.

Answer:

B

Step-by-step explanation:

The question can be written is

5^x = 75

Now take the log of both sides.

log(5x) = log(75)            Bring the x outside the brackets

x log(5) = log(75)           Divide by log 5

x = log(75)/log(5)

log 75 = 1.8751

log 5 = .8990

x = 1.8751/.8990 = 2.6826

Answer:

  (b)  2.68

Step-by-step explanation:

Your question has a link to a suitable calculator. All you need to do is make use of it. It tells you log₅(75) ≈ 2.68.

__

Other ways to look at the problem

If you recall that a logarithm represents an exponent of the base, you can ask yourself, what power 5 must be raised to in order to get 75. You know that 5^2 = 25, and 5^3 = 125, so the power will have to be between 2 and 3. There is only one answer choice in that range: 2.68.

__

The rules of logarithms let you rewrite the given expression as ...

  log₅(75) = log₅(3×5²) = log₅(3) +2·log₅(5) = log₅(3) +2

The log₅ of any number between 1 and 5 will be a positive fraction, so this sum must be between 2 and 3.

Answer:

  x = 120/17

Step-by-step explanation:

In this arrangement of right triangles, each is similar to any other. Then the ratio (long side)/(hypotenuse) is the same for all.

  long side/hypotenuse = BD/BA = CB/CA

  x/8 = 15/17

  x = 8(15/17)

  x = 120/17

Answer:

B

Step-by-step explanation:

One approach is to plug (2, -2) to every function and only B will work.

Choice A) y = 3x + 4

-2 = 3(2) + 4

-2 = 10

Does not work

Choice B) y = -3x + 4

-2 = -3(2) + 4

-2 = -2

Works

Choice C) y = -1/3x + 4

-2 = -1/3(2) + 4

-2 = -2/3 + 4

-2 = -2/3 + 12/3

-2 = 10/3

Does not work

Choice A) y = 4x - 3

-2 = 4(2) - 3

-2 = 5

Does not work

You can also just take a look at the function and see that its slope is downwards so it has to be negative. Then check the slope using rise/run.

For every 1 to the right it goes down 3, so -3/1 = -3. The only function with a slope of -3 is answer choice B.

Step-by-step explanation:

Answer:

93.25

Step-by-step explanation:

One meter = 100 cm

9300 divided by 100 = 93 + 0.25 = 93.25

The conversion of the given measurement of 9325 cm to meters is gotten as; 93.25 meters

There are different units in mathematics to convert. However, in this case, we want to convert centimeters to meters.

Now, the conversion rate here is;

100cm = 1m

Thus, to convert 9325 cm to meters we will just divide it by 100.

Thus;

9325 cm = 9325/100 = 93.25 meters

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

[tex]A(t) = A(0)(1 + rt)[/tex]

In which:

In this problem, considering than an year has 365 days, the parameters are as follows:

[tex]A(t) = 204, A(0) = 200, t = \frac{30}{365}[/tex]

Hence:

[tex]A(t) = A(0)(1 + rt)[/tex]

[tex]204 = 200\left(1 + \frac{30}{365}r\right)[/tex]

[tex]1 + \frac{30}{365}r = \frac{204}{200}[/tex]

[tex]\frac{30}{365}r = 0.02[/tex]
