Answer:
[tex]94 + 49i[/tex]
Step-by-step explanation:
Given
[tex]2 + \sqrt{-121[/tex] and [tex]3 + \sqrt{-64[/tex]
Required
Determine the products
We have:
[tex](2 + \sqrt{-121}) * (3 + \sqrt{-64})[/tex]
Factorize:
[tex]2(3 + \sqrt{-64}) + \sqrt{-121} (3 + \sqrt{-64})[/tex]
Open Brackets
[tex]6 + 2\sqrt{-64}+ 3\sqrt{-121} + \sqrt{-121} *\sqrt{-64}[/tex]
[tex]6 + 2\sqrt{-64}+ 3\sqrt{-121} + \sqrt{-121*-64}[/tex]
[tex]6 + 2\sqrt{-64}+ 3\sqrt{-121} + \sqrt{7744}[/tex]
Expand the expression in square roots
[tex]6 + 2\sqrt{-1 * 64}+ 3\sqrt{-1 * 121} + \sqrt{7744}[/tex]
Split roots
[tex]6 + 2\sqrt{-1} * \sqrt{64}+ 3\sqrt{-1} * \sqrt{121} + \sqrt{7744}[/tex]
Take positive square roots of 64, 121 and 7744
[tex]6 + 2\sqrt{-1} * 8+ 3\sqrt{-1} * 11 + 88[/tex]
[tex]6 + 16\sqrt{-1}+ 33\sqrt{-1}+ 88[/tex]
Collect Like Terms
[tex]88 + 6 + 16\sqrt{-1}+ 33\sqrt{-1}[/tex]
[tex]94 + 49\sqrt{-1}[/tex]
A complex number in standard form is:
[tex]a + bi[/tex]
Where
[tex]i = \sqrt{-1[/tex]
So:
[tex]94 + 49\sqrt{-1}[/tex]
=
[tex]94 + 49i[/tex]
Hence:
The product of [tex]2 + \sqrt{-121[/tex] and [tex]3 + \sqrt{-64[/tex] is [tex]94 + 49i[/tex]
a wooden fruit crate will hold 62 pounds of fruit. the crate already has 18 pounds of fruit in it. which inequality represents the solution set that shows the pounds of fruits ,p, that can be added to the crate
Answer:
[tex]p + 18 \leq 62[/tex]
Step-by-step explanation:
Given
[tex]Total = 62\ lb[/tex]
[tex]Current = 18\ lb[/tex]
Required
Write an inequality to represent the scenario?
Represent the additional number of pounds with p.
When p is added to the current pounds, the weight must be less than or equal to the total possible weights
In other words:
[tex]p + current \leq total[/tex]
Substitute values for current and total
[tex]p + 18 \leq 62[/tex]
Hence, the inequality that describes the scenario is: [tex]p + 18 \leq 62[/tex]

The top of the tallest mast of a sail boat is 48 feet above sea level. The boat's anchor is resting on the sea bed 24 feet below sea level. Represent the vertical distance from the top of the mast to the anchor's position, in feet, with a subtraction expression. Solve the subtraction expression and explain how it can be written as an addition expression instead.
Answer:
the answer is 48-24=24. but you can turn it into addition by adding 24+24 then it would have the same answer: 48 feet

You can find the angles of all of those easily just from angle 1, but for angle 5 and 6 you can't
to find angle one it's obviously what it says
to find 2 and 4 you do 180-whatever angle one is
to find angle 3 it's the exact same of angle one because they are like opposite or whatever.
Find an equation of the line, in point-slope form, that passes through (-2,3) with a slope of -4
Step-by-step explanation:
let the eqn be y - y1 = m (x - x1)
sub (-2, 3) and m = -4:
y - (-2) = -4 (x - (-2))
y + 2 = -4 (x + 2)

Using π = 3.14, find the area of a circle with a radius of 5.6. Round your answer to the nearest hundredth.
Answer:
98.47
Step-by-step explanation:
A = πr²
A = (3.14)(5.6)²
According to PEMDAS exponents come before multiplication. 5.6² is 31.36
The next step is to multiply this answer by pi (3.14)
3.14*31.36 = 98.47

Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 17 , upper bound is 25. The point estimate of the population mean is:_______ The margin of error for the confidence interval is:_______
Answer:
Population mean = 21
Margin of error = 4
Step-by-step explanation:
Given that
Lower bound of the population is 17
Upper bound of the same population is 25
The population mean, x-bar is calculated by saying
x-bar = (lower bound + upper bound)/2
x-bar = (17 + 25)/2
x-bar = 42/2
x-bar = 21
Margin of error for the confidence interval is gotten by
E = (upper bound - lower bound)/2
E = (25 - 17)/2
E = 8/2
E = 4
Thus, the mean is 21, while the error is 4
Slope = -1; y-intercept = 8 write the linear equation in slope intercept form
Step-by-step explanation:
Slope intercept form is y=mx+c, where m is the slope and c is the y-intercept
y = -1*x + 8
y=-x+8
Solve this question—————-
Answer: (2, -5) (light blue answer choice)
Solving by substitution
−7x+y=−19;−2x+3y=−19
−7x+y+7x=−19+7x (Add 7x to both sides)
y=7x−19
Step: Substitute7x−19 for y in −2x+3y=−19:
−2x+3y=−19
−2x+3(7x−19)=−19
19x−57=−19 (Simplify both sides of the equation)
19x−57+57=−19+57 (Add 57 to both sides)
19x=38
19x/19 = 38/19 (Divide both sides by 19)
x=2
Step: Substitute 2 for x in y=7x−19:
y=7x−19
y=(7)(2)−19
y= −5 (Simplify both sides of the equation)
Therefore: x = 2 and y = −5

Your family is planning a 6-day trip to Florida. You estimate that it will cost $450 per day in Tampa and $600 per day in
Orlando. Your total budget is $3000. Which of the following is the system of equations that represents this situation?
Step-by-step explanation:
set day in Tampa = x
and day in orlando= Y
x +y=6 X= 6 -y
450 x + 600 y = 3000
. 450 (6 - y ) + 600 y= 3000
2700 - 450y + 600y = 3000
150y = 300
y= 2 X= 4
so Spend 4 days in Tampa and 2days in orlando
How can I resolve (with steps) 2*(4^2x+3) = 1/8
Answer:
-47/256
Step-by-step explanation:
Divided both sides by 2
2(4^2+3)/2=1/8/2
Simplify
16x+3=1/16
Subtract 3 from both sides
16x+3-3=1/16-3
Simplify
16x=-47/16
Divided both sides by 16
16x/16=-47/16/16
Simplify
x=-47/256
Hope this helped! :)
