What is the value of X?

Answer:

d = 19

Step-by-step explanation:

________________________________

FACTS TO KNOW BEFORE SOLVING :-

For a cuboid with dimensions l , b & h ,

Diagonal of a cuboid = [tex]\sqrt{l^{2} + b^{2} + h^{2}}[/tex]

________________________________

According to the question ,

l = 10 ; b = 6 ; h = 15

So , Diagonal of the cuboid (d) =

[tex]d = \sqrt{10^{2} + 6^{2} + 15^{2}} = \sqrt{100 + 36 + 225} = \sqrt{361} = 19[/tex]

C. 2%; exponential decay

You can use the fact that increasing power of values lying between 0 and 1 results in less and less values.

The percent rate of change in given function is -2%

The function represents exponential decay.

For finding this, first find how much the output y changes if we change x from x to x + 1.

Output when x = x:   [tex]y = (0.98)^x[/tex]

Output when x = x+1:  [tex]y = (0.98)^{x+1}[/tex]

Difference in output if x goes from x to x+1: [tex](0.98)^{x+1} - (0.98)^x = (0.98)^x(0.98 - 1) = -0.02 \times (0.98)^x[/tex] (this change occurs if we increase input x by 1 unit, thus this also represents the rate)

Rate of change of function per unit increment = [tex]-0.02 \times (0.98)^x[/tex]

The percentage of rate of change is found as:

[tex]\text{Percent rate of change\:} = \dfrac{\text{Rate of change} \times 100}{\text{previous value}} = \dfrac{-0.02 \times (0.98)^x \times 100}{(0.98)^x} \\\\ \text{Percent rate of change\:} = -2\%[/tex]

Thus, the percent rate of change is -2%

The negative sign shows that the value is decreasing, thus showing that function shows exponential decay.

Answer:

The Dairy Farm is better deal.

Step-by-step explanation:

Given that:

Per gallon charges of the Spotted Cow = $2.80

Delivery fee = $2

Let,

x be the gallons of milk.

S(x) = 2.80x + 2

Putting x = 20

S(20) = 2.80(20) + 2 = 56 + 2

S(20) = $58

Per gallon charges of the Dairy Farms = $2.10

Delivery fee = $10

D(x) = 2.10x + 10

Putting x = 20

D(20) = 2.10(20) + 10 = 42 + 10

D(20) = $52

Hence,

The Dairy Farm is better deal.

[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]

Step-by-step explanation:

Prime numbers are those numbers in which they can be divided by itself and 1. They are formed by two natural numbers higher than 1 but not by multiplying natural numbers that are smaller.

So; using index notation to writing 512 as a product of primes; we have:

[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]

Answer:

7.4 miles per hour

Step-by-step explanation:

The distance of the pigeon from the nest is 5.8 km.

In order to determine the distance of the pigeon from its nest, the Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where:

3² + 5²

= 9 + 25

= 34

√34 = 5.8 km.

Step-by-step explanation:

Answer:

The number of degrees through which the pointer rotates is approximately 20°.

Step-by-step explanation:

If the pointer moves, then it is moving in form of an arc. Since the length of the pointer is 6cm, then radius formed with the pointer is 6cm in length.

When it moves 2.1cm on the scale, an arc with length of 2.1cm is formed.

Using the formula for the length of an arc, we can get the desired number of degrees, angle in degrees, needed.

Length of an arc = 2πrA/360°

Length of the arc = 2.1cm

r = 6cm

A = the angle in degrees.

Therefore we have:

2.1 = 2xπx6xA/360

2.1 = πA/30

(2.1x30)/π = A

A ≈ 20°

The number of degrees through which the pointer rotates when it moves 2.1 centimeters on the scale is; 20°

When the pointer moves 2.1 centimetres on the voltmeter scale;

In essence, since the length of an arc is given by;

where, R = radius = 6cm

Therefore;

p = 20°.

Step-by-step explanation:

The distance covered by Dennis will be 9.23 miles.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and does not require any direction to represent it.

Given that Dennis can walk about 2(5/6) miles each hour. The distance covered by Dennis in 3 hours 15 minutes will be calculated as:-

Distance = 2 ( 5 /  6)  x  3 hour 15 minute

Distance = 2.84 x 3 ( 1 / 4)

Distance = 2.84 x 3.25

Distance = 9.23 miles.

Therefore, the distance covered by Dennis will be 9.23 miles.
