Show all work to multiply (3+ /(-16))(6-/(-64))
Answer:
=50
Step-by-step explanation:
The product of (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]) is 50.
The given expression is (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]).
We need to find the product for it.
How slove negative square roots?Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
Now, (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex])=(3+4i)(6-8i)
=18+24i-24i-32i²
=18+32=50 (∵i²=-1)
Hence, the product of (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]) is 50.

solve the inequality: 8(7-x)<64
Answer: x>-1
solving For X
Answer:
x > -1
Step-by-step explanation:
8(7-x)<64 (solve for x)
56 - 8x < 64 (distribute!)
-8x < 8 (subtracted 56 from both sides)
x > -1 (divide by -8, flip sign anytime you divide by a negative!)

what is the probability that the number chosen is multiple of of 3 given that is it a factor of 24
Answer:
You have a 50% chance of picking a multiple of 3.
Step-by-step explanation:
If we include 1 and 24 as factors of 24, then the possible choices would be:
1, 2, 3, 4, 6, 8, 12, 24
Of those, the only ones that are multiples of 3 are 3, 6, 12 and 24. Meaning that the chance of getting a multiple of 3 is 4/8, or 1/2, i.e. 50%
If we don't include 1 and 23, then we have:
2, 3, 4, 6, 8, 12
and 3, 6 and 12 are divisible by 3.
Which again gives 1/2, or 50%
So regardless of whether 1 and 24 are included, the chance of picking a multiple of three from the factors of 24 is 50%.
1. A firm manufactures tables and desks. To produce each table requires 1 hour of labor, 10 square
feet of wood, and 2 quarts of finish. To produce each desk requires 3 hours of labor, 20 square feet
of wood, and 1 quart of finish. Available is at most 45 hours of labor, at most 350 square feet of
wood, and at most 55 quarts of finish. The tables and desks yield profits of $4 and $3 respectively.
Find the number of each product to be made in order to maximize profits. Find the maximum
profit.
9514 1404 393
Answer:
25 tables, 5 desks, for a profit of $115
Step-by-step explanation:
Let x and y represent the numbers of tables and desks to build, respectively. The we want to maximize 4x+3y subject to the constraints ...
x +3y ≤ 45 . . . . . constraint on labor
10x +20y ≤ 350 . . . . . constraint on wood
2x +y ≤ 55 . . . . . constraint on finish
These inequalities are graphed in the attachment. The vertex of the feasible region that maximizes profit is (x, y) = (25, 5).
The product mix that maximizes profit is ...
25 tables
5 desks
for a profit of 25·4 +5·3 = 115 dollars.

Naina emptied a tank holding 65 L 400 ML of water into 12 bottles. What will be the capacity of each bottle.
Answer:
The capacity of each bottle is 5.45 of waters or 5 L 450 ML of water
Step-by-step explanation:
We are told that:
Naina emptied a tank holding 65 L 400 ML of water into 12 bottles.
We have 65 Liters and 400ml , we convert everything to Liters
1000ml = 1 L
400ml = x L
Cross Multiply
1000 × x = 400 × 1 L
x = 400/1000
x = 0.4L
Hence, the total capacity of the tank, is 65L + 0.4L = 65.4L
Since there are 12 bottles, we assume that each bottle are of the same size hence, the capacity of each bottle is
calculated as:
12 bottles = 65.4 L
1 bottles = x
Cross Multiply
12x = 65.4L
x = 65.4L /12
x = 5.45 L
Hence, the capacity of each bottle is 5.45 or 5 Liters, 450 ML

Please i need an answer urgently. Sum of 3 terms are 252, first term is 192. Find common ratio
Answer:
[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]
Step-by-step explanation:
Geometric Sequences
The geometric sequence is given as:
[tex]a_1, a_1r, a_1r^2, a_1r^3,..., a_1r^{n-1}[/tex]
Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:
[tex]\displaystyle S_n=a_1\frac{r^n-1}{r-1}[/tex]
We are given: S3=252, a1=192, thus substuting:
[tex]\displaystyle 252=192\frac{r^3-1}{r-1}[/tex]
Dividing by 12:
[tex]\displaystyle 21=16\frac{r^3-1}{r-1}[/tex]
Recall that:
[tex]r^3-1=(r-1)(r^2+r+1)[/tex]
Substituting:
[tex]\displaystyle 21=16\frac{(r-1)(r^2+r+1)}{r-1}[/tex]
Simplifying:
[tex]21=16(r^2+r+1)=16r^2+16r+16[/tex]
Rearranging:
[tex]16r^2+16r+16-21=0[/tex]
16r^2+16r-5=0
Rewriting:
[tex]16r^2-4r+20r-5=0[/tex]
Factoring:
[tex]4r(4r-1)+5(4r-1)=0[/tex]
[tex](4r-1)(4r+5)=0[/tex]
Solving:
[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]
Both solutions are valid

suppose line AT bisects ∠CAR. if ∠CAT = 5x and ∠CAR = 9x +7, what is ∠TAR
Answer:
∠TAR = 35°
Step-by-step explanation:
∠TAR = ∠CAR - ∠CAT = (9x + 7) - 5x = 4x + 7
AT bisect ∠CAR ∠TAR = ∠CAT
4x + 7 = 5x
x = 7
∠TAR = 4 x 7 + 7 = 35
