Answer:

a = 10

Step-by-step explanation:

The image is showing a linear pair which equals 180°
104° is shown.

If you take 180° and subtract 104° you should get the answer to what (8a -4)° should equal to.

180° - 104° = 76°

Your equation should look like : 8a - 4 = 76°
-- Add 4 to both sides

8a - 4 = 76°
     +4    +4

= 8a = 80
-- Divide 8 on both sides

8a/8 = 80/8

a = 10

Proof:

8(10) - 4 =
80 - 4 = 76°

104° + 76° = 180°

Hope this helps!

The number of gigabytes Bao can use while staying within her budget is 3.9 gigabytes.

From the information, plan, Bao pays a flat cost of $40.50 per month and $5 per gigabyte and she wants to keep her bill under $60 per month.

The inequality will be:

40.50 + 5g < 60

where g = number of gigabytes

40.50 + 5g < 60

5g < 60 - 40.50

5g < 19.50

g < 19.50 / 5

g < 3.9

Therefore, the number of gigabytes will be less than 3.9 g.

The solution of the given equation by rounding off it to the nearest ten-thousandth is 10.0427.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation:  log 4 + 2 log x = 6

We are given a logarithmic expression: log 4 + 2 log x = 6  

We know that e^(log b) = b

a log b = (log b)^a

log a + log b = log (ab)

Using exponential on both sides, we have

e^(log 4 + 2 log x) = e^6

e^(log 4 + log x² ) = 403.428

e^(log 4x² ) = 403.428

4x² = 403.428

x² = 403.428 / 4

x² = 100.857

x = 10.0427

Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 10.0427.

well, for the piece-wise function, we'd like to know f(-2), or namely what is f(x) when x = -2?

well, f(x) is 2 for x = -1

f(x) is 4 for x > -1

keeping in mind that in the negative side of the number line, the closer to 0, the larger, thus -1 is much larger than -1,000, so  hmmm -2 is farther from 0 than -1 is, so -1 is larger than -2, so when x = -2, x < -1, and the function that applies when x < -1 is -(x+1)² + 4, so then

[tex]f(x)= \begin{cases} -(x+1)^2 + 4&\stackrel{-2}{x} < -1\\\\ 2&x=-1\\\\ 4&x > -1 \end{cases} \\\\\\ f(-2)\implies -(~~(-2)+1~~)^2 + 4\implies -(-1)^2+4\implies -(-1)(-1)+4 \\\\\\ -(1)+4\implies -1+4\implies \text{\LARGE 3}[/tex]

Answer: f(-2)=3

Step-by-step explanation:

[tex]f(x)=\left\{\begin{array}{ccc}-(x+1)^2+4\ for\ x < -1\\2\ \ \ \ for\ \ x=-1\\4\ \ \ for \ \ \ x > -1\end{array}\right[/tex]

Given that the expression is log₄2+log₄8.

We are required to express the given expression in single logarithm.

Product property of logarithm basically tells that says that the logarithm of a product is equal to a sum of logarithms and because logs are exponents, and we multiply like bases, we can add the exponents.

The expression is log₄2+log₄8.

log₄2+log₄8=[tex]log_{4}[/tex](8*2) (We are not required to write the base separately)

The negation is "antarctica is not in the northern hemisphere" &  the truth value of the original proposition is FALSE and its negation is TRUE.

The sentences that can be classified as true or false , but not both are called as propositions.

For Example , "Shirt is yellow" is a proposition whereas "a is less than 2" is not a proposition as the value of a is not fixed.

Negation of proposition means writing the opposite of the given proposition.

If the proposition is true then it's truth value is "True".

If the proposition is false then it's truth value is "False".

According to the given Question

The negation of the statement "antarctica is in the northern hemisphere" is "antarctica is not in the northern hemisphere"

The truth value of the original proposition is FALSE as Antarctica is in the Southern hemisphere.

Answer:

Step-by-step explanation:

first you take out the exponent (2) by getting the square root of 18 so the equation will be 4x+3=18squared rooted. the primary factors of 18 are 2*3 squared. so instead of 18 put the factors is.so now you will get

4x+3=3^2*2 square rooted.

then you apply the radical rule so square root each of the digits.that will simplify to 4x=3square rooted by 2 divide by 4 on both sides minus 3/4 and if you simplify it should give you the answer

The two numbers are 12 and 20

Let the small number be x

Let the large number be y

We have that;

y = 8 + x      (1)

But;

x + y = 32    (2)

Now, substitute the value of y as 8 + x in equation (2)

x + 8 + x = 32

collect like terms

2x + 8 = 32

2x = 32 - 8

2x = 24

Make 'x' the subject

x = 24/ 2

x = 12

But;

y = 8 + x

y = 8 + 12

y = 20

Thus, the two numbers are 12 and 20

the negations of the hypothesis and conclusion for the given conditional statement are:

not P = "The sum of the interior angle measures of a polygon is not 180°"

not Q = "The polygon is not a triangle"

For two defined propositions P and Q, we define a conditional statement as a sentence of the form:

If P, then Q.

Particularly in this case, P is called the hypothesis and Q is called the conclusion of the conditional statement.

For the given one:

"If the sum of the interior angle measures of a polygon is 180, then the polygon is a triangle."

We will have that the hypothesis is:

The sum of the interior angle measures of a polygon is 180°

The conclusion will be:

The poñyogn is a triangle.

Now we want to negate these two, it is really simple, for the hypothesis we will have that the sum of the interior angles can be any number but 180°, then we can write the negation as:

"The sum of the interior angle measures of a polygon is not 180°

Similar for the conclusion, we just need to state that the polygon is not a triangle, we will get:

"The polygon is not a triangle"

Then the negations of the hypothesis and conclusion for the given conditional statement are:

not P = "The sum of the interior angle measures of a polygon is not 180°"

The output value of f(5) in the given function f(x) = -4x - 5 is -25

A function is simply a set of ordered pairs where each first element is paired with one and only second element and also no element in either pair is without a partner.

Given the data in the question;

To determine the output value of f(5), replace the variable x with 5 and simplify.

f(x) = -4x - 5

f(5) = -4(5) - 5

Perform the multiplication operation to remove the parenthesis.

f(5) = -4(5) - 5

f(5) = -20 - 5

f(5) = -25

Answer:

Answer: 57 & 59

Step-by-step explanation:

Let us assume first odd integer is 'x'

Then, next consecutive integer should be 'x+2'. RIGHT?

Now, put in the form of equation:

x + (x+2) = 116

x + x + 2 = 116

2x + 2 = 116

2x = 116 - 2

2x = 114

x = 114 / 2 => 57

Now, put the value of 'x' in second step:

           x + 2 => 57 + 2 = 59
