Answer:

g = 1 1/8

Step-by-step explanation:

g/(3/4) = 1 1/2

g = 1 1/2(3/4) = 1 1/8

Answer:

A general exponential equation is written as:

y = a*(b)^x

Where:

y represents the amount of something as a function of the variable x, where x is an independent variable.

a is the initial amount, this is, the value of y when x = 0.

b is the rate of growth, this defines how much changes the value of y as x increases.

Length of the ladder = 13 m

Foot of the ladder from the wall = 5 m.

The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.

In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.

In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.

In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.

So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.

Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m

wall ^ 2 + ground ^ 2 = 13^2 = 169

w^2 + g^2 = 169

w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12

Rate of change of ground distance = dg / dt = 2m/s (given).

In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.

2 w dw/dt + 2 g dg/dt = 0

2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0

dw/dt = -20 / 24 = -5 / 6

Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)

The minus sign denotes that the height of the ladder is falling.

Answer:

[tex]y=\frac{1}{2}x+3[/tex]

Step-by-step explanation:

Let y equal the total amount of time spent on homework. Regardless of Shaunda's time spent on homework, represented by x, Zack spends half the time, represented by the 1/2. The additional 3hrs represents the y intercept, making it added on to the 1/2x expression.

If I helped, a brainliest answer would be greatly appreciated!

Answer:

Ken class has a median of 84 while Judy class a median of 87

Step-by-step explanation:

Ken class has a median of 84 while Judy class a median of 87

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Step-by-step explanation:

Answer:

a) 21 √m inches

b) 13√2/2 m

Step-by-step explanation:

a) we want to find the perimeter of an equilateral triangle

An equilateral triangle is one which sides has the same equal length

The perimeter of this triangle is the sum of the lengths of the three sides

Mathematically, we have this as:

7 √m + 7 √m + 7 √m

= 21 √m inches

b) we want to calculate the perimeter of the given rectangle

Mathematically, we can calculate the perimeter of a rectangle using the formula below;

P = 2(l + b)

where l represents the length of the rectangle and b represents the breadth of the rectangle

From the given shape;

l = √50 m, b = 1/2 √32

So, we have the perimeter follows;

2( √32/2 + √50)

= √32 + √50/2

√32 = 4√2

√50 = 5√2

Thus, we have;

4 √2 + 5 √2/2

= (8 √2 + 5 √2)/2 = 13√2/2

Answer:

75% off

Step-by-step explanation:

Answer:

The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.

Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.

Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)

x= 180-105 = 75°

Pls mark as brainliest

Answer: x = 72

Step-by-step explanation:

The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y

a + y + y = 180 (sum of angles in triangles)

58 + 2y = 180

Subtract 58 from both sides

2y = 122

Divide both sides by 2

y = 61°

In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.

b = 47°

y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.

y + b + x = 180

61 + 47 + x = 180

108 + x = 180

Subtract both sides by 108

x = 72

Answer:

Exactly 1

Step-by-step explanation:

y = 2 x + 1

Step-by-step explanation:

Answer:

396π.cm^3

Step-by-step explanation:

ere's your solution

=> height of cylinder = 11 cm

=> radius of cylinder = 6 cm

=> volume = πr^2h

=> putting the value of radius and height in formula

=>volume = 6^2*11 π

=> volume = 36*11 π

=> Volume = 396π .cm^3

Step-by-step explanation:

Answer:

Height = 8 units

Step-by-step explanation:

Area of a triangle = [tex]36\frac{4}{5}[/tex] square units

                             = [tex]\frac{184}{5}[/tex] square units

Height of the triangle = [tex]9\frac{1}{5}[/tex] units

                                    = [tex]\frac{46}{5}[/tex] units

Formula to calculate the area of a triangle is,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

[tex]\frac{184}{5}= \frac{1}{2}\times (\frac{46}{5})\times (\text{Height})[/tex]

[tex]\frac{184}{5}= (\frac{46}{10})\times (\text{Height})[/tex]

Height = [tex]\frac{184}{5}\times \frac{10}{46}[/tex]

           = [tex]\frac{368}{46}[/tex]

           = 8 units

Therefore, height of the given triangle is 8 units.
