Find the measure of angle a.
a
50°

Answer:

1

Step-by-step explanation:

f(x) = a(2) + 6 = 2a + 6

Given f(2) = 8

so 2a + 6 = 8

2a = 8 - 6 = 2

so a = 1

Step-by-step explanation:

The reduced row echelon form* of ...

  [tex]\left[\begin{array}{ccc|c}4&5&-6&2\\-3&-2&7&-15\\-1&4&2&-13\end{array}\right][/tex]

is ...

  [tex]\left[\begin{array}{ccc|c}1&0&0&-3\\0&1&0&-2\\0&0&1&-4\end{array}\right][/tex]

which tells you the value of 'a' is -3.

_____

* Many scientific and/or graphing calculators and web sites can find the reduced row echelon form of a matrix for you. Or, for a single variable (such as 'a'), you can use Cramer's rule. That requires you compute two 3×3 matrix determinants. Again, there are many calculators, apps, and web sites that will make this calculation for you.

  [tex]a=\dfrac{\left|\begin{array}{ccc}2&5&-6\\-15&-2&7\\-13&4&2\end{array}\right| }{\left|\begin{array}{ccc}4&5&-6\\-3&-2&7\\-1&4&2\end{array}\right|}=\dfrac{147}{-49}=-3[/tex]

The two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.

A dot plot can be described as a simple form of data visualization that shows the frequency at which each data points in the data set occurs, which are plotted as dots.

The data set of the measures of the fossils taken by the paleontologist include the following data points and the frequency at which they occur and how they are represented on a dot plot:

We are told that the paleontologist found two errors, where a length of two fossils that measure 7.9 are recorded as 8.1 and 8.2.

Therefore, if the correct measures are used to draft a new dot plot, we would have the following data points and number of dots representing the correct frequency of each measures:

Therefore, the two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.

Yes.

Step-by-step explanation:

The expression 2y + 6 could be used to denote the tree's height.

A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.

Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years

Expression = 2y + 6

Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.

therefore, an Expression that represents the height of the tree would be 2y + 6.

Answer:

3x-3y+4

Step-by-step explanation:

x-3y+2x+4

Assume the coefficient of term x is 1, so: 1x-3y+2x+4

1x and 2x are the only like terms, so we combine them and the final answer is:

Answer:

0.3024

Step-by-step explanation:

Given the following :

Probability of breaking pinata on first hit = 0.58;

P(first hit break) = 0.58

P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42

P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72

Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

P(does not break on first hit) * p(2nd hit break)

0.42 * 0.72 = 0.3024

X=7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.

Answer:

277 591.1 ft³

Step-by-step explanation:

First, use the formula for circumference to solve for the diameter.

Circumference = πd

295.3 = πd

295.3/π = d

94 ft = d

Then, divide the diameter by 2 to find the radius.

r = d/2

r = 94/2

r = 47 ft

Now, use the value of the radius with the given height in the formula for volume of a cylinder.

V = πr²h

V = π(47²)(40)

V = 277 591.1 ft³

Answer:

105

Step-by-step explanation:

Assuming A^2 + B^2 = C^2:

C^2 = 4 + 3 = 7

So,

C^2 * 15 = 49(15) = 105

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

Step-by-step explanation:

there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.
