We can simplify the exponent by multiplying 10 to itself 7 times.

= 10 * 10 * 10 * 10 * 10 * 10 * 10

= 100 * 10 * 10 * 10 * 10 * 10

= 1000 * 10 * 10 * 10 * 10

= 10000 * 10 * 10 * 10

= 100000 * 10 * 10

= 1000000 * 10

= 10000000

10^7 = 10,000,000

Step-by-step explanation:

BC is tangent to the circle with center A at point C and AC is radius.

[tex] \therefore AC \perp BC\\

\therefore \angle ACB =90°\\[/tex]

Now by Pythagorean theorem:

[tex] AB^2 = AC^2 + BC^2 \\

\therefore AC^2 = AB^2-BC^2\\

\therefore x^2 = 17^2-14^2\\

\therefore x^2 =289-196\\

\therefore x^2 =93\\

\therefore x =\sqrt{93}\\

\therefore x =9.64365076\\

The key characteristics of graph of f(x) = cosecx are, The range of the function is (−∞, −1]∪[1, ∞) and Asymptotes occurs every π, beginning at x = 0. So statements 1 & 3 are correct

Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.

There are 6 commonly used functions in trigonometry with their name and abbreviations-

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)

Given that,

A trigonometric function,

f(x) = cosecx

The range of cosecx is (−∞, −1]∪[1, ∞)

At x = 0, it is approaching to infinity from both the sides

So, y intercept is not 1

At every π interval, it has Asymptotes

It never intersects the x axis, So x-intercept is not exist here

Hence, statements 1 & 3 are correct

The graph of f(x)=cscx has a range of (−∞, −1]∪[1, ∞) , no y-intercept, and asymptotes at every multiple of \pi, but no x-intercepts.

The key characteristics of the graph of the function f(x)=cscx include the following:

This is because the cosecant function is the reciprocal of the sine function, which ranges from -1 to 1.

So, the cosecant function will take on all values that are less than -1 or greater than 1.

The sine function, which is the reciprocal of the cosecant, equals 0 at this point, and division by zero is undefined.

since cosecant is the reciprocal of sine, the function is undefined at these points;

so statement c is incorrect.

Answer:

4.73

Step-by-step explanation:

4 8/11=4+8/11

=4/1+811

=(4/1×11/11)+8/11

=44/11+8/11=52/11

We know that

52/11

is the same as

52÷11

Then using

Long Division for 52 divided by 11

and rounding to a Max of 2 Decimal Places gives us

=4.73

Final answer:

The equivalent decimal to the mixed number 4 8/11 is 4.7273, achieved by dividing 8 by 11 to get 0.7273 and adding it to the whole number 4.

Explanation:

To write the mixed number 4 8/11 as a decimal, we need to convert the fractional part to decimal form and then add it to the whole number. To convert the fraction 8/11 to a decimal, we divide the numerator by the denominator using a calculator or long division.

Dividing 8 by 11 gives us approximately 0.7273. Now we add this decimal to the whole number 4 to get the decimal equivalent of the mixed number. The final result is 4.7273.

Remember that when rounding to four decimal places, if necessary, you look at the fifth decimal place to determine whether to round up or leave the fourth place as is. Since we do not have a fifth decimal place in this conversion, our four-decimal-place number is accurate as is.

We will be left with 5 g of Cesium-137 after 90 years, given its half-life of 30 years and the initial quantity we have as 40 g.

Many elements tend to decompose over some time. The period over which an element reduces to half of itself in quantity is called the half-life of that substance.

The formula for the quantity of the element at a certain time t can be given as:

[tex]N_{t} = N_{0}\left ( \frac{1}{2} \right )^{\frac{t}{t_{1/2}}}[/tex]

Where,

[tex]N_{t}[/tex] is the quantity of the element at time t,

[tex]N_{0}[/tex] is the initial quantity of the element,

[tex]{t_{1/2}[/tex] is the half-life of the element.

In the question, we are given that an element, Cesium-137 has a half-life of approximately 30 years.

We are asked to find the quantity of this element left after 90 years when we had an initial sample of 40 g.

To solve for the quantity left, we can use the formula for the quantity of the element at a certain time t can be given as:

[tex]N_{t} = N_{0}\left ( \frac{1}{2} \right )^{\frac{t}{t_{1/2}}}[/tex]

Where,

[tex]N_{t}[/tex] is the quantity of the element at time t,

[tex]N_{0}[/tex] is the initial quantity of the element,

[tex]{t_{1/2}[/tex] is the half-life of the element,

by taking t = 90 years, [tex]N_{0}[/tex] = 40 g, [tex]{t_{1/2}[/tex] = 30 years, and [tex]N_{t}[/tex] = ?.

∴ [tex]N_{t} = N_{0}\left ( \frac{1}{2} \right )^{\frac{t}{t_{1/2}}}[/tex]

or, [tex]N_{t} = 40\left ( \frac{1}{2} \right )^{\frac{90}{30}}} g[/tex]

or, [tex]N_{t} = 40\left ( \frac{1}{2} \right )^{3}} g[/tex]

or, [tex]N_{t} = 40\left ( \frac{1}{8} \right ) g[/tex]

or, [tex]N_{t} = 5 g[/tex] .

∴ We will be left with 5 g of Cesium-137 after 90 years, given its half-life of 30 years and the initial quantity we have as 40 g.

The answer is x-5 or "B" on edge

Step-by-step explanation:

Given : If the hypotenuse of a 30-60-90 triangle has length 15 then the shorter leg has length  5.5 , 6.5 , 7.5.

To find : What is the length of the other leg and hypotenuse ?

Solution :

For a  30-60-90 triangle, sides are in the ratio  [tex]1:\sqrt{3}:2[/tex]

where, 1 is the shorter side,  

[tex]\sqrt{3}[/tex] the other side

and 2 the hypotenuse.

Short leg = 5.5

Other leg = [tex]5.5\times \sqrt3=5.5\sqrt3[/tex]

Hypotenuse = [tex]5.5\times 2=11[/tex]

Short leg = 6.5

Other leg = [tex]6.5\times \sqrt3=6.5\sqrt3[/tex]

Hypotenuse = [tex]6.5\times 2=13[/tex]

Short leg = 7.5

Other leg = [tex]7.5\times \sqrt3=7.5\sqrt3[/tex]

Hypotenuse = [tex]7.5\times 2=15[/tex]

Final answer:

In a 30-60-90 triangle with a hypotenuse of 15, the shorter leg has a length of 7.5, based on the ratio 1:√3:2.

Explanation:

If the hypotenuse of a 30-60-90 triangle has length 15, then to find the length of the shorter leg, we can use the properties of this special right triangle. In a 30-60-90 triangle, the ratio of the lengths of the sides is 1:√3:2. In other words, if the shorter leg is 'x', the longer leg is 'x√3', and the hypotenuse is '2x'.

Since the hypotenuse is 15, we set '2x' equal to 15 and solve for 'x':

2x = 15

x = 15 / 2

x = 7.5

The shorter leg of the triangle has a length of 7.5.

The longest line that can be drawn in a right rectangular prism (a box) is the diagonal from one corner to the opposite corner. This is called the space diagonal. It can be calculated using the Pythagorean theorem in three dimensions. In this case, the longest line is 16.8 cm.

The longest line that can be drawn in a right rectangular prism, also known as a box, is the diagonal drawn from one corner of the box to the opposite corner. This longest line is also known as the space diagonal of the box. To find the length of the space diagonal, we use the Pythagorean theorem in three dimensions, which is given by the formula d = √(l² + w² + h²), where l, w, and h are the length, width, and height of the box respectively.

In this case, the length l is 13 cm, the width w is 8 cm, and the height h is 7 cm. Thus, the length of the space diagonal is d = √((13 cm)² + (8 cm)² + (7 cm)²) = √(169 cm² + 64 cm² + 49 cm²) = √282 cm² = 16.8 cm. Therefore, the longest line segment that can be drawn in the box is 16.8 cm long.

The longest line segment that can be drawn in the prism is approximately 16.79 cm long.

 First, we calculate the diagonal of the base of the prism, which is the rectangle with dimensions 13 cm by 8 cm.

The diagonal of this rectangle can be found using the Pythagorean theorem in two dimensions:

[tex]\[ d_{\text{base}} = \sqrt{l^2 + w^2} \][/tex]

[tex]\[ d_{\text{base}} = \sqrt{13^2 + 8^2} \][/tex]

[tex]\[ d_{\text{base}} = \sqrt{233} \][/tex]

 Next, we find the diagonal of the entire prism by considering the diagonal of the base and the height of the prism:

[tex]\[ d_{\text{prism}} = \sqrt{d_{\text{base}}^2 + h^2} \][/tex]

[tex]\[ d_{\text{prism}} = \sqrt{(\sqrt{233})^2 + 7^2} \][/tex]

[tex]\[ d_{\text{prism}} = \sqrt{282} \][/tex]

 Therefore, the longest line segment that can be drawn in the prism is the space diagonal, which is approximately:

[tex]\[ d_{\text{prism}} \approx \sqrt{282} \][/tex]

[tex]\[ d_{\text{prism}} \approx 16.79 \text{ cm} \][/tex]

 So, the longest line segment that can be drawn in the prism is approximately 16.79 cm long.
