Answer:
[tex]4 \sqrt{2}[/tex]
Step-by-step explanation:
Rewrite 32 as the product of 16 and 2:
[tex]\implies \sqrt{32}=\sqrt{16 \cdot 2[/tex]
Apply exponent rule [tex]\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}[/tex]
[tex]\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}[/tex]
Rewrite 16 as 4²:
[tex]\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}[/tex]
Apply exponent rule [tex]\sqrt{a^2}=a[/tex]
[tex]\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}[/tex]
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
[tex]\sqrt{32}[/tex]
= [tex]\sqrt{16(2)}[/tex]

csc x - cos x • cot x = sin x
Answer: The answer is (d) ⇒ cscx = √3
Step-by-step explanation:
∵ sinx + (cotx)(cosx) = √3
∵ sinx + (cosx/sinx)(cosx) = √3
∴ sinx + cos²x/sinx = √3
∵ cos²x = 1 - sin²x
∴ sinx + (1 - sin²x)/sinx = √3 ⇒ make L.C.M
∴ (sin²x + 1 - sin²x)/sinx = √3
∴ 1/sinx = √3
∵ 1/sinx = cscx
∴ cscx = √3
In the figure, ABCD is a cyclic quadrilateral in which AC and BD are its diagonals. If ∠DBC = 55° and ∠BAC 45°, Find ∠BCD.
Given,
ABCD is a cyclic quadrilateral in which AC and BD are its diagonals.
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
[tex] \sf∠DBC= 55° and ∠BAC = 45°[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
Thus,
[tex] \sf∠DAB=∠CAD + ∠BAC[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \sf= 55° + 45° [/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
We know that the opposite angles of a cyclic quadrilateral are supplimentary.
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
[tex] \sf ∠DAB +∠BCD = 180°[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
[tex] \sf∠BCD = 180°-100° =80°[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \:[/tex]
[tex] \pink{\boxed{\sf{∠BCD = 80°}}}[/tex]
Answer:
∠BCD = 80°
Step-by-step explanation:
Given -ABCD is a cyclic Quadrilateral.
∠DBC = 55°
∠BAC = 45°
To find -∠BDC
Solution..BC is a segment and angles of same segment are equal.=> ∠BAC = ∠BDC
=> 45° = ∠BAC { Angles of same segment BC}
In Triangle BCD
=> ∠BDC + ∠DBS + ∠BCD = 180°
=> 45° + 55° + ∠BCD = 180°
=> 100° + ∠BDC = 180°
=> ∠BDC = 180-100
=> 80° ans.

Jamar read 252 pages in 3/4 of an hour. At what rate, in pages per hour, did he read?
Answer:
336 pages per hour (pretty fast)
Step-by-step explanation:
It's hard to explain for me (I'm just doing my best to answer it) but I got the answer from estimating values with a calculator. The proof of it as an answer can be seen from this equation: 336 * 0.75 (or 3/4) = 252. It's pretty late for me so I'm having a hard time reverse engineering the equation. Hopefully this still helps though. :)
Answer:
336 pages per hourStep-by-step explanation:
Given rate is
252 pages per 3/4 of an hourDivide both numbers by 3/4 to get the unit rate per hour

Answer:
22.62 degrees
Step-by-step explanation:
Right triangle
you can pick cosine or sine to calculate angle r
sin r = opposite leg/ hypotenuse = 5/13
arcsin(5/13) = 22.62 degrees
cos r = 12/13
r = arccos(12/13) = 22.62 degrees

Can somebody help me find the area of this composite shape
Alone, this shape cannot have the area solved in one step. So, you must break it up into multiple pieces.
For this, we can break it up into a rectangle, and a right triangle.
The area formula for a rectangle is [tex]area = l*w[/tex]
The area formula for a right triangle is [tex]area = \frac{1}2} b*h[/tex]
To find the area of the rectangle, multiply 14 * 18 = 252 m^2
To find the length of the triangle, subtract 20 - 14 = 6
To find the height of the triangle, subtract 18 - 11 = 7
So, it is [tex]\frac{1}{2} 6*7[/tex] = 21 m^2
21 + 252 = 273 meters squared

Donna travels 70 miles at an average speed of 40 mph. she then travels a further 30 miles. the average speed for the entire journey is 44 mph. assuming donna didn't stop, what was her average speed for the final 30 miles to 2 dp?
If donna didn't stop, her average speed for the final 30 miles to 2 dp is; 57.39 mph
How to Calculate Average Speed?We are given;
Distance travelled by Donna = 70 miles
Average Speed of Donna = 40 mph
Additional Distance travelled = 30 miles
Average speed for entire journey = 44 mph
We know that;
time = distance/speed
Thus
Total time = (70 + 30)/44
Total time = 100/44 h
Time 1 = 70/40 = 7/4 hr
Time 2 = 30/v
Thus;
30/v + 7/4 = 100/44
Multiply through by 44 to get;
1320/v = 100 - 77
v = 1320/23
v = 57.39 mph

Rachel found that 20 out of 48 cars that entered a parking lot were red. What is the experimental probability that the next car that comes in is red? What is the experimental probability that the next car that comes in is not red?
In the observation of Rachel the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.
What is experimental probability?Experimental probability of an event is the ratio of number of favorable outcome which appeared while conducting an event to the total number of outcome of that event is occurred.
Rachel found that 20 out of 48 cars that entered a parking lot were red. In this observation, the probability of a car to be red is,
[tex]P=\dfrac{20}{48}\\P=\dfrac{5}{12}[/tex]
Thus, the experimental probability that the next car that comes in is red is 5/12.
The experimental probability that the next car that comes in is not red is,
[tex]P^{-1}=1-\dfrac{5}{12}\\P^{-1}=\dfrac{12-5}{12}\\P^{-1}=\dfrac{7}{12}[/tex]
Hence, In the observation of Rachel, the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.
