Answer:

35 minutes

Step-by-step explanation:

The total time he walked for last week is

10 * 5 = 50 minutes

Subtract 225 by 50 to find the total time he spend for swimming

225-50 = 175 minutes

Divide 175 by 5 to find the time taken for swimming on each day

175/5 = 35 minutes

Answer:

  75582

Step-by-step explanation:

The order of the correct problems does not matter, so the number of ways 8 of 19 problems can be correct is the number of combinations of 19 things taken 8 at a time:

  C(n, k) = n!/(k!(n-k)!)

  C(19, 8) = 19!/(8!(11!)) = 75582

Answer:

25.2

Step-by-step explanation:

Secant-Tangent Formula:

(whole secant) x (external part) = (tangent)^2

(41+12) * 12 = x^2

( 53) * 12 = x^2

636= x^2

Taking the square root of each side

sqrt(636) = x

25.2=x

Answer:

25.2

Step-by-step explanation:

This is an intersection of a tangent and a secant.

Answer:

 43y2+3 + 7y + 1

Step-by-step explanation:

Answer:

h(x) = f(x - 12) - 4

Step-by-step explanation:

y = f(x) (-6, 11)

⬇️ ⬇️

y - h(x) (6, 7)

so h(x) = f(x - 12) - 4

Answer:

[tex]7\sqrt{2} \ cm[/tex]

Step-by-step explanation:

Formula ………………………………………………

The length of a diagonal of a square with side of length “a” is :

[tex]a\sqrt{2}[/tex]

======================================================

Since a = 7 (in our case) then

[tex]\text{the length of the diagonal} =7\sqrt{2}[/tex]

Note : you can also use the Pythagorean theorem.

The time that is taken for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds

Given that this is a cosine equation,

At maximum, Cos (0) =1

At minimum, Cos (π) = -1.

Hence,

At the maximum:

At the minimum:

Given that the time taken from max to min is 0.625 and also to min to max is also 0.625,

The total time taken would be:

0.625 + 0.625 = 1.25s

x = -1

Step-by-step explanation:

[tex] \sf\frac{x}{x - 2} + \frac{x - 1}{x + 1} = - 1[/tex]

Taking LCM

[tex] \sf \hookrightarrow \frac{x(x + 1) + (x - 1)(x - 2)}{(x - 2)(x + 1)} = - 1 \\ \\ \sf \hookrightarrow \frac{ {x}^{2} + x + {x}^{2} - 3x + 2 }{ {x}^{2} - x - 2} = - 1 \\ \\ \sf \hookrightarrow \frac{2 {x}^{2} - 2x + 2 }{ {x}^{2} - x - 2 } = - 1[/tex]

Cross multiplying

[tex] \sf \hookrightarrow 2 {x}^{2} - 2x + 2 = - 1( {x}^{2} - x -2) \\ \\ \sf \hookrightarrow 2 {x}^{2} - 2x + \cancel2 = - {x}^{2} + x + \cancel2 \\ \\ \sf \hookrightarrow 3 {x}^{2} - 3x = 0[/tex]

Taking 3 common

[tex] \sf \hookrightarrow {x}^{2} - x = 0 \\ \\ \sf \hookrightarrow x(x - 1) = 0 \\ \\ \sf \hookrightarrow x - 1 = 0 \\ \\ \\ \green{\boxed{ \hookrightarrow x = 1}}[/tex]

Taking x as 1

[tex] \sf \implies\frac{x}{x - 2} + \frac{x - 1}{x + 1} = - 1 \\ \\ \sf \implies \frac{1}{1 - 2} + \frac{1 - 1}{1 + 1} = - 1 \\ \\ \sf \implies - 1 + 0 = - 1 \\ \\ \sf \implies - 1 = - 1[/tex]

V = length(9) × width(6) × height(8) ÷ 3 = 144

Answer:

see explanation

Step-by-step explanation:

the standard form of a quadratic expression is ax² + bx + c ( a ≠ 0 )

(1)

(2x + 5)(x + 1)

each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 1) + 5(x + 1) ← distribute parenthesis

= 2x² + 2x + 5x + 5 ← collect like terms

= 2x² + 7x + 5 ← in standard form (a = 2, b = 7, c = 5 )

(2)

(x - 2)(x + 2)

= x(x + 2) - 2(x + 2) ← distribute parenthesis

= x² + 2x - 2x - 4 ← collect like terms

= x² - 4 ← in standard form (a = 1, b = 0, c = - 4 )

Answer:

a) None

b) (0, -2)

Step-by-step explanation:

The x-intercept is the point at which the line cuts through the x-axis, while the y-intercept in the point at which the line cuts through the y-axis.

a) The line does not cut through the x-axis, thus it has no x-intercept.

b) The line cuts through the y-axis at y= -2, making its y-intercept (0, -2).

Step-by-step explanation:

Check the picture below.

Answer:

#3 : x = 12

#4 : x = 6

Step-by-step explanation:

Question 3:-

Question 4:-

Answer:

x = 15

∠AOB = 15°

∠BOC = 165°

Step-by-step explanation:

Angles on a straight line add up to 180°

[tex]\sf \implies \angle AOB + \angle BOC=180[/tex]

Substitute the given expressions for the angles:

[tex]\sf \implies (2x - 15) + 11x = 180[/tex]

Collect and combine like terms:

[tex]\sf \implies 2x +11x- 15=180[/tex]

[tex]\sf \implies 13x- 15=180[/tex]

Add 15 to both sides:

[tex]\sf \implies 13x- 15+15=180+15[/tex]

[tex]\sf \implies 13x=195[/tex]

Divide both sides by 13:

[tex]\sf \implies \dfrac{13x}{13}=\dfrac{195}{13}[/tex]

[tex]\sf \implies x=15[/tex]

Now substitute the found value of x into the expressions for each angle:

[tex]\sf \implies \angle AOB =2(15)-15=15^{\circ}[/tex]

[tex]\sf \implies \angle BOC =11(15)=165^{\circ}[/tex]

it is the answer on the top
