Hope this helps :)

the answer to the expression 8:4(5+2) is approximately 0.2857.

To solve the expression 8:4(5+2), we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

First, we simplify the expression inside the parentheses: 5 + 2 = 7.

Next, we perform the multiplication: 4 * 7 = 28.

Finally, we perform the division: 8 ÷ 28 = 0.2857 (rounded to four decimal places).

So, the answer to the expression 8:4(5+2) is approximately 0.2857. Remember that it's crucial to follow the order of operations to arrive at the correct result in mathematical expressions.

Answer:

   44. (1) -15x³y³ - 3x³y²

Step-by-step explanation:

Question 44

The linear function that represents the line y - 2 = 4(x - 3), in slope-intercept form, is expressed as: D. f(x)y = 4x - 10.

A linear function equation is expressed as, y = mx + b, in slope-intercept form.

Given the point-slope equation of the function, y - 2 = 4(x - 3), rewrite in slope-intercept form:

y - 2 = 4(x - 3)

y - 2 = 4x - 12

y = 4x - 12 + 2

y = 4x - 10

The linear function would be: D. f(x)y = 4x - 10

Answer:

I think the answer is b ill look into it a Lil more

b = speed of the boat in still water

c = speed of the current

when going Upstream, the boat is not really going "b" fast, is really going slower, is going "b - c", because the current is subtracting speed from it, likewise, when going Downstream the boat is not going "b" fast, is really going faster, is going "b + c", because the current is adding its speed to it.

now, going either way the boat travelled the same 18 miles.

Answer:

x= 2, y= -3

Step-by-step explanation:

Given two equations, we can solve them by either substitution or elimination method. Let's solve by substitution!

x -y= 5

Rewrite this equation such that one of the variable is the subject of formula, so that we can substitute this equation into the second.

x= y +5 -----(1)

3x +y= 3 -----(2)

Substitute (1) into (2):

3(y +5) +y= 3

Expand:

3y +15 +y= 3

4y= 3 -15

4y= -12

y= -12 ÷4

y= -3

Substitute y= -3 into (1):

x= -3 +5

x= 2

The interpretations of the function values are: the cost of buying 0, 10 and 67.5 gallons of paint would be 0, 28.5 and 73.9, respectively

The equation of the function is given as:

f(x) = 9√x

When x = 0, 10 and 67.5, we have:

f(0) = 9√0 = 0

f(10) = 9√10 = 28.5

f(67.5) = 9√67.5 = 73.9

Hence, the interpretations of the function values are:

The cost of buying 0, 10 and 67.5 gallons of paint would be 0, 28.5 and 73.9, respectively

Answer:

  (a)  362.5 m²

Step-by-step explanation:

The ratio of areas is proportional to the square of the ratio of side lengths.

__

  larger/smaller = (35 cm)/(28 cm) = 5/4

The larger area is the square of this scale factor times the smaller area.

  (5/4)²(232 m²) = 362.5 m²

Additional comment

We assume the units are intended to match. It is impossible for a pentagon with a side length of 28 cm to have an area of 232 m². A regular pentagon with a side length of 28 cm will have an area of about 0.1349 m².

Answer:

841854.7 ft²

Explanation:

[tex]\sf Formula \ for \ area \ of \ sector = \dfrac{\theta}{360 } \ x \ \pi r^2[/tex]

Here given:

Hence solve for area of sector:

[Insert values]

[tex]\rightarrow \sf \dfrac{60}{360 } \ x \ \pi (1268)^2[/tex]

[simplify]

[tex]\rightarrow \sf 841854.6778[/tex]

[round to nearest tenth]

[tex]\rightarrow \sf 841854.7[/tex]

Answer:

  841,854.7 ft²

Step-by-step explanation:

The area of the sector can be found using the appropriate area formula. The central angle in radians is required.

  A = 1/2r²θ . . . . where r is the radius, and θ is the central angle in radians

__

The 60° angle corresponds to 60° × π/180° radians, or π/3 radians. The area of the 60° sector is then ...

  A = 1/2(1268 ft)²(π/3) = 803912/3π ft² ≈ 841,854.7 ft²

Substitute the given values and solve for AB:

[tex]\implies \sf \sin(\theta)=\dfrac{O}{H}[/tex]

[tex]\implies \sf AB=\dfrac{4}{\sin(35^{\circ})}[/tex]

Therefore, AB = 6.97 (nearest hundredth)

A strategy which would produce a new confidence interval with an increased margin of error is to: A. use a 98% confidence level.

A confidence interval simply refers to a range of estimated values which defines the probability that a population parameter will lie within it.

Mathematically, a margin of error is calculated by using this formula:

[tex]MOE_{\gamma}=Z_{\gamma} \times \sqrt{\frac{\sigma^2}{n} }[/tex]

From the above formula, we can deduce that the margin of error is directly proportional to the critical value and inversely proportional to the square root of sample size.

This ultimately implies that, increasing the confidence level from 95% to 98% would increase the critical value and by extension the margin of error and vice-versa.
