Hey there!

To answer this question you have to plug in your values and do PEMDAS.
PEMDAS simply means

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

WE CAN ANSWER THE EQUATION

1/4(c^3 + d^2)

= 1/4(-4^3 + 10^2)

= 1/4(-64 + 100)

= 1/4(-64) + 1/4(100)

= -16 + 25

= 9

OR

1/4(c^3 + d^2)

= 1/4(-4^3 + 10^2)

= 1/4(36)

= 9

Therefore, your answer is: 9

Good luck on your assignment & enjoy your day!

Answer:

6.8

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

First, you will pick the first equation :

(x*20)

Then the next,

(x*20) + 5

Then the last equation,

(x*20) + 5 = 5*13

Then you solve

20x + 5 = 65

20x = 65 - 5

20x = 60

20x/20 = 60/20

x = 3

Answer:

about 11.99 inches

Step-by-step explanation:

Using the formula for the volume of a right circular cylinder:

Answer:

25 miles

Step-by-step explanation:

well
1/100 = 0.25
10/100 = 2.5 (Because 0.25 x 10)
100/100 = 25 (Because 0.25x100)

Answer:

0.0893 meters per year

Step-by-step explanation:

Answer:

t≤. -2

Step-by-step explanation:

2≤ -t

Dividing both sides by -1,

The sign flips over,

2/-1 ≥ -t/-1

-2≥t

t≤-2

Answer:

5, 6, 7

Step-by-step explanation:

let the 3 consecutive integers be n , n + 1 , n + 2 , then

n(n + 2) = n+ 1 + 29

n² + 2n = n + 30 ( subtract n + 30 from both sides )

n² + n - 30 = 0 ← in standard form

(n + 6)(n - 5) = 0 ← in factored form

equate each factor to zero and solve for n

n + 6 = 0 ⇒ n = - 6

n - 5 = 0 ⇒ n = 5

n > 0 , then n = 5

the 3 integers are 5, 5 + 1, 5 + 2 , that is

5, 6, 7

Firstly this looks like translated log function graph

log1=0

As per graph the graph is pulled some inwards y axis but little bit

Usually log x leaves y axis at -1 but here it leaves at +2

So

y axis is moved upwards (+3)

Last function

Answer:

1000000000000000000000000000000 kg / 1E + 30 kg

Step-by-step explanation:

10³⁰ kg

Calculate 10 thirty times,

= (10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10) kg

=1000000000000000000000000000000 kg

= 1E + 30 kg

#5. Which equation represents the linear function shown in the table? *

х: 2, 4, 6

у: -1, -5, -9

⇢-1 = -2 x 2 +3

⇢-1 = -4+3

⇢-1 =-1 ✓

⇢-5 = -2 x 4 +3

⇢-5 = -8 +3

⇢-5 = -5 ✓

⇢ -9 = -2 x 6 +3

⇢ -9 = -12 +3

⇢ -9 = -9 ✓

O y = 2x + 3

O y = -3x + 2

O y = 3x - 2

The solution is, O y = -2x + 3,  represents the linear function shown in the table.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

let the equation be y = -2x + 3.

putting the value of x as 2 & y as -1

⇢-1 = -2 x 2 +3

⇢-1 = -4+3

⇢-1 =-1 ✓

putting the value of x as 4 & y as -5

⇢-5 = -2 x 4 +3

⇢-5 = -8 +3

⇢-5 = -5 ✓

putting the value of x as 6 and y as -9

⇢ -9 = -2 x 6 +3

⇢ -9 = -12 +3

⇢ -9 = -9 ✓

we get, that this satisfies the conditions,

so, we have, O y = -2x + 3

Hence, The solution is, O y = -2x + 3,  represents the linear function shown in the table.

Answer:

log = cylinder

board = rectangular prism

Step-by-step explanation:

The log has a radius of 5 in and a length of 30 in.  

This implies that the cross-section is a circle, and so it can be modeled as a cylinder.

The board has a width of 5.5 in, a height of 1.5 in and a length of 3ft.

Therefore, it can be modeled as a rectangular prism.

10/7

hope it helps...!!!

Answer:

18/7

Step-by-step explanation:

Since m<2 includes 1, m<2 = m<1

9x = 2x + 2 ⇒ 7x = 2 ⇒ x = 2/7

m<1  = 2(2/7) + 2 = 4/7 + 14/7 = 18/7

The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.

The answer will be All non-negative real numbers less than or equal to 18

because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".

To find the median

 ⇒ must define what is a median

    ⇒Definition of median: middle number of an ordered set

Lets look at the information given

 Set when ordered: 13,15, 17,x,20,21     with median of 18

  ⇒ In this case, there is an even number of numbers

    ⇒ to find the median

       ⇒ must find average of two numbers closest to the middle

             ⇒ which are 'x' and '17' which is equal to the given median 18

Let's set up the equation:

  [tex]\frac{x+17}{2} =18\\x+17=36\\x=19[/tex]

Answer: x = 19

Step-by-step explanation:

assuming 4 weeks in a month

$19.50 * 38 * 4 =  $ 2964   per month

.28 * 2964 = 829.92

He really cannot afford this rent......

Answer:

A.    $829.92        B. No

Step-by-step explanation:

A.   38 hours time $19.50 = $741 per week; Monthly: $741 x 4 = $2,964.00

      28% of monthy income = .28 x $2,964.00 = $829.94

B.  No, he can not afford the home.     Cost of the home is $1, 700.00

      ( No more than 28%) well 28% of $2,964 = $829.94

Answer:

  7.789×10^-2 = 0.07789 cm

Step-by-step explanation:

Your calculator can find the difference of the two given diameters and express it in any format you like.

The attached image of a calculator display shows the difference of the cell diameters is 0.07789 = 7.789×10^-2 cm.

__

The difference of two numbers with different exponents is found by first adjusting the exponents so they are the same. Here, we choose to adjust both numbers so they have the highest exponent value.

  8.83×10^-2 - 6.01×10^-3

  = 8.39×10^-2 - 0.601×10^-2 = (8.39 -0.601)×10^-2 = 7.789×10^-2

Alternatively, you can convert both numbers to standard form and do the subtraction that way.

  8.83×10^-2 - 6.01×10^-3

  = 0.0883 -0.00601 = 0.07789

Additional comment

The second attachment shows the relationship between place values and their multiplier in scientific notation.

__

The choice of exponent when computing the sum or difference of numbers in scientific notation is usefully informed by an estimate of the value of the sum or difference. A proper choice can avoid the need to adjust the exponent of the result of the operation. Here, we see the subtraction will change the larger value by less than 10%, so the exponent of the result in scientific notation will be that of the larger value (-2).

Answer:

c is the correct one

Step-by-step explanation:

6/8 = 0.75 > 4/8 = 0.5

Recall (or "define", if you're not familiar) the so-called ceiling and floor functions, or least/greatest integer functions, respectively; for any integer n,

• ceiling function:

[tex]\lceil x \rceil = n \text{ if } n-1 < x \le n[/tex]

• floor function:

[tex]\lfloor x \rfloor = n \text{ if } n \le x < n+1[/tex]

Let x and y be the two numbers Serena picks. She finds that

[tex]\lceil x \rceil \lceil y \rceil = 100[/tex]

[tex]\lfloor x \rfloor \lfloor y \rfloor = X[/tex]

Assume x and y are not integers. Let m and n be two integers such that m - 1 < x < m and n - 1 < y < n. Then

[tex]\lceil x \rceil \lceil y \rceil = mn = 100[/tex]

so m and n are divisors of 100. There's a finite number of distinct divisor pairs (m, n) to consider,

(± 1, ± 100), (± 2, ± 50), (± 4, ± 25), (± 5, ± 5)

whose sums can be one of

± 101, ± 99, ± 52, ± 48, ± 29, ± 21, ± 10, 0

Similarly,

[tex]\lfloor x \rfloor \lfloor y \rfloor = (m-1)(n-1) = 101 - (m + n) = X[/tex]

which is maximized if the sum m + n is negative; the largest of these is m + n = -101, so the maximum value of X is 101 + 101 = 202.

The reasoning for the case of either x or y, or both, being integers is nearly identical.
