What is the length of the diagonal of the square shown below?

Tatiana [17]

Answer:

sqrt(50)

Step-by-step explanation:

Since it is a right triangle, we can apply the Pythagorem Theorem.

a^2 + b^2 = c^2

25 + 25 = c^2

50 = c^2

c = sqrt(50)

Lines AB and CD (if present in the picture) are straight lines. Find x. Give reasons to justify your solutions.

ziro4ka [17]

Answer:

1. Angle Addition Postulate/Theorem

2. 90°

3. m<AOC; Vertical Angles

4. 90°; 110°

5. 20°

Step-by-step explanation:

1. m<DOB = m<DOE + m<BOE (Reason: Angle Addition Postulate/Theorem)

2. m<DOB = 90° + x (Reason: Substitution)

Note: m<DOE is a right angle.

3. m<DOB = m<AOC (Reasons: Vertical Angles)

4. 90° + x = 110° (Reasons: Substitution)

5. x = 20° (Reasons: Algebra)

Note how we got 20° by applying algebra:

90° + x = 110°

Subtract 90° from both sides

90° + x - 90° = 110° - 90°

x = 20°

Drag each tile to the correct box. Not all tiles will be used

Illusion [34]

Answer:

$\frac{2(vt-d)}{t^2}=a$

Step-by-step explanation:

Expression to calculate the displacement 'd' is,

d = vt - $\frac{1}{2}at^{2}$

By subtracting vt from both the sides of the equation.

d - vt = - $\frac{1}{2}at^2$

vt - d = $\frac{1}{2}at^{2}$ --------(1)

Multiplying with 2 on both the sides of the equation,

2(vt - d) = at² --------(2)

Dividing by 't²' on both the sides of the equation,

$\frac{2(vt-d)}{t^2}=\frac{at^2}{t^2}$

$\frac{2(vt-d)}{t^2}=a$ --------(3)

Therefore, expression to calculate the acceleration 'a' will be

$\frac{2(vt-d)}{t^2}=a$

musickatia [10]

Answer:

The 99% confidence level (-0.741, -0.659).

Step-by-step explanation:

The average body mass index (BMI) in a sample of 1559 men was 30.4, with a standard deviation of 0.6.

The average BMI in a sample of 1924 women was 31.1 with a standard deviation of 0.2.

Find a 99% confidence interval for the difference between the mean weights..

The formula for 99% Confidence Interval for difference between the mean weights =

μ is the population mean, and σ is the population standard deviation.

μ1 - μ2 ± z × √σ²1/n1 + σ²2/n2

The z score for 99% confidence interval = 2.576

30.4 - 31.1 ± 2.576 × √0.6²/1559 + 0.2²/1924

-0.7 ± 2.576 × √0.36/1559 + 0.04/1924

-0.7 ± 2.576 × √0.0002309173 + 0.00002079

-0.7 ± 2.576 ×√0.0002517073

-0.7 ± 2.576 × 0.015865286

-0.7 ± 0.04086897674

Hence, the 99% Confidence Interval is

-0.7 - 0.04086897674

= -0.74086897674

≈ -0.741

-0.7 + 0.04086897674

=-0.65913102326

≈ -0.659

Therefore, the 99% confidence level (-0.741, -0.659).
