Using the graph, determine the equation of the axis of symmetry.
Answer:
x = 6
Step-by-step explanation:
The axis of symmetry passes through the vertex of the graph
It is a vertical line with equation
x = c ( c is the x- coordinate of the vertex )
vertex = (6, 1 ) with x- coordinate 6 , then
equation of axis of symmetry is x = 6
10 fewer than the difference of 8 and w! Please helpppppppp!!!!!!!! get 5 stars and brainly and heart!!!!!!!
Answer:
(8-w) -10
Step-by-step explanation:
fewer than comes after
difference of 8 and 2
(8-w)
10 fewer than
(8-w) -10
Answer:
(8 - w) - 10
Step-by-step explanation:
10 fewer than the difference of 8 and w.
-10
fewer means that we are taking away something, so it is minus.
8 and w (difference)
and is a word that adds something, but we have to pay attention to the difference. that means -.
8 - w
Put parenthesis around it so we know it is 8 and w that seperates from the (10 fewer).
(8 - w)
add - 10 at the end
(8 - w) - 10
simplify (4+√3)(4-√3)
Answer:
13
Step-by-step explanation:
(4+√3)(4-√3) = (4)^2-(√3)^2 =16-3 = 13
Answer:
Step-by-step explanation:
(a + b)(a -b) =a² - b²
a = 4 and b = √3
(4 + √3)(4 - √3)= 4² - (√3)²
= 16 - √3*√3
= 16 - 3
= 13
A man makes a profit of 15%6y selling an article for Rs 2500. For what price should he sellituto make a profit of 38%
Find the price before the 15% profit:
2500 / 1.15 = 2173.91
Now multiply the original cost by 1 + 38%:
2173.91 x 1.38 = 2999.99
Answer: 2.999.99 ( may need to round to 3,000)
calculate the speed, in ms-¹ of vehicle A and of vehicle B
9514 1404 393
Answer:
A: 0.32 m/sB: 0.56 m/sStep-by-step explanation:
The speed is the ratio of the change in distance to the corresponding change in time.
Vehicle A moves from a position of 12 m to one of 28 m in 50 seconds, so its speed is ...
A = (28 -12)/50 m/s = 16/50 m/s = 0.32 m/s
Vehicle B moves from 0 to 28 m in 50 seconds, so its speed is ...
B = (28 m)/(50 s) = 0.56 m/s
Solve for x if 25'+ 3(5') = 4
Answer:
x=0
Step-by-step explanation:
Let 5x = y.
(52)x+3(5x)−4=0
y2+3y−4=0
y2−y+4y−4=0
y(y−1)+4(y−1)=0
(y+4)(y−1)=0
y=−4;y=1
y = -4 is not possible.
y = 1 ⟹ x = 0.
Answer:

Which of the following is equivalent to 0.00451?
A. 4.51x10^-3
B. 45.1x10^-3
C. 0.451x10^-3
D. 4.51x10^-2
Step-by-step explanation:
0.00451
[tex] = \frac{451}{100000} [/tex]
[tex] = \frac{4.51}{1000} [/tex]
[tex] = \frac{4.51}{ {10}^{3} } [/tex]
[tex] = 4.51 \times {10}^{ - 3} (option \: a)(ans)[/tex]
The required scientific notation is A. 4.51x10⁻³ is equivalent to 0.00451. It's in scientific notation where 4.51 is between 1 and 10, and -3 is the exponent representing the decimal shift.
In scientific notation, a number is written in the form of "a × 10ⁿ" where "a" is a number between 1 and 10 (including 1 but excluding 10), and "n" is an integer exponent.
The goal is to represent the number in a more compact form using powers of 10.
0.00451
To express this in scientific notation, we need to find "a" and "n" such that "a × 10ⁿ" equals 0.00451.
The option A, 4.51 × 10⁻³ is the correct choice because:
"a" is 4.51, which is between 1 and 10.
"n" is -3, as we are shifting the decimal point three places to the left to convert 0.00451 to 4.51 × 10⁻³.
Therefore, 0.00451 is equivalent to scientific notation option A. 4.51 × 10⁻³, which is option A.

The circumference of a circle is 16πw⁴.
Derive an expression for the area in terms of pi and w
Answer:
A = Pi (8 w**4)**2
Step-by-step explanation:
C = 16 Pi w**4 (given)
C = 2 Pi R (stand forula)
So then find R in terms of w by settting C = C from above
2 Pi r = 16 Pi w**4
2R = 16 w**4
R = 8 w**4
SO
A = Pi R**2
A = Pi (8 w**4)**2

please help!! this is geometry
Step-by-step explanation:
1 and 3 are complimentary angles, meaning 1+3 = 180 degrees.
in the same way 1 and 2 are complimentary angles, 1+2 = 180, => 2 ≈ 3
and for 2 and 4 the same => 1 ≈ 4
3 and 5 are complimentary angles, 3+5 = 180 degrees, => 1 ≈ 5.
7 and 8 are complimentary angles, 7+8 = 180 degrees, => (given that 1 ≈ 7 and therefore ≈ 4) 8 ≈ 2 ≈ 3
6 and 8 are complimentary angles, 6+8 = 180 degrees, => 6 ≈ 7 ≈ 1
and with 1≈5 and 1≈6 we know 5≈6.

Find 'x' in the following
First we have to find angle D
As it is a quadrilateral
[tex]\\ \sf\longmapsto <A+<B+<C+<D=360[/tex]
[tex]\\ \sf\longmapsto 45+50+35+<D=360[/tex]
[tex]\\ \sf\longmapsto 130+<D=360[/tex]
[tex]\\ \sf\longmapsto <D=360-130[/tex]
[tex]\\ \sf\longmapsto <D=230°[/tex]
Now
[tex]\\ \sf\longmapsto <D+x=360[/tex]
[tex]\\ \sf\longmapsto x+230=360[/tex]
[tex]\\ \sf\longmapsto x=360-230[/tex]
[tex]\\ \sf\longmapsto x=130°[/tex]
Answer:
x = 130
Step-by-step explanation:
Sum of all the angle of quadrilateral = 360°
50 + 45 + 35 + ∠ADC = 360
130 + ∠ADC = 360
∠ADC = 360 - 130
∠ADC = 230
x = Reflex ∠ADC
= 360 - 230
= 130

the Marked price of a book is rupees 160 if it is sold at 15% discount find the discount amount and selling price
answer is 15%
Step-by-step explanation:
cost prices of book =160
selling prices of book =136
now,rate of discount =loss% (as discount only leads to some kind of loss)
so CP>SP
so loss=CP-SP =160-136=24
loss%= (loss/CP)÷100
=(24/160)÷100
=15%
so rate of discount =15%

Step-by-step explanation:
15) should be b) 6.7, 6 as the median is the average of the 25th and 26th result, these both occur in the 6 group and is the only option with a whole number for median
To check the mean
(2(4) + 7(5) + 17(6) + 10(7) + 8(8) + 6(9)) / 50 = 6.66 ≈ 6.7
16) mode is 1 child as the single largest grouping is 11 families
there were 46 families polled so the median occurs between 23 and 24
7 + 11 + 6 is 24 therefore median falls under 2 children.

A square has a perimeter of of 28 m. What is the length of each side
Answer:
a square has 4 sides therefore the formula for perimeter of a square would be 4a where a is the number of sides. in this case, we want to know the length of each side so we divide total length (28) by number of sides which is 4 and we get 7m
Answer:
the side lengths of a square are equal. Second, know that the sum of all 4 side lengths gives us the perimeter.
