100x2=200

so its 2 times greater

The annual rate of decay is r = 0.87

We know that if a quantity has a half-life of T, then the rate of decay must be such that:

r^T = 0.5

This means that when a time T passes, the original quantity becomes half of what it originally was.

In this case we know that the half-life is T = 5 years, then we have:

r^5 = 0.5

r = 0.5^(1/5) = 0.87

Then the annual rate of decay is r = 0.87, and if the initial quantity is 18 grams, we can write the exponential decay as:

f(t) = 18g*(0.87)^t

Step-by-step explanation:

I took the test on edge and got it right

Answer:

52%

Step-by-step explanation:

There are 25 filled in squares in the first image, and 13 filled in squares in the second image.

To find the percentage we can divide the part of the base (a) by the base (b).

a = 13

b = 25

13/25 = 0.52

[tex]\large{\boxed{\sf Chord = 8cm }}[/tex]

Step-by-step explanation:

First see figure in attachment . As we know that ,Perpendicular from centre of the circle bisects the chord . Hence here ,

[tex]\sf\qquad\longrightarrow AB = 2AC = 2x [/tex]

Now in ∆OAC , by Pythagoras Theorem , we have ;

[tex]\sf\qquad\longrightarrow (5cm)^2= x^2+(3cm)^2\\ [/tex]

[tex]\sf\qquad\longrightarrow 25cm^2=x^2+9cm^2\\[/tex]

[tex]\sf\qquad\longrightarrow x^2=25cm^2-9cm^2\\[/tex]

[tex]\sf\qquad\longrightarrow x^2=16cm^2\\ [/tex]

[tex]\sf\qquad\longrightarrow \pink{ x = 4cm } [/tex]

Therefore , the length of chord will be ,

[tex]\sf\qquad\longrightarrow AB = 2x \\ [/tex]

[tex]\sf\qquad\longrightarrow AB = 2(4cm)\\[/tex]

[tex]\sf\qquad\longrightarrow \pink{ AB = 8cm } [/tex]

Hence the length of chord is 8cm .

Answer:

Step-by-step explanation:

Let Kayla made number of 2 points shots = x

and the number of 3 points shots = y

Since she made total nine shots so the equation will be

x + y = 9 --------(1)

She scores a total of 22 points so the equation will be

2x + 3y = 22 --------(2)

Now we multiply equation (1) by 2 and subtract it from equation (2)

(2x + 3y) - 2(x + y) = 22 - 18

2x + 3y - 2x - 2y = 4

y = 4

from equation (1)

x + 4 = 9

x = 5

Therefore, number of 2 shots are 5 and number of 3 shots are 4.

Answer:

The area of the circular park is about 1017.88

Step-by-step explanation:

First, we recall the area of a circle.

A=  πr^2

Next, we plug in the radius

A=  π*18^2

A=  π*324

A= 1017.88

To conclude, that is how you find the area of a circular park.

Answer:

C) 3.5 hours

Step-by-step explanation:

30 minutes is a half of an hour.

So that would be seven halves of an hour.

If we multiply the amount of halves by the amount of day late we get our answer.

0.5 x 7 = 3.5

Or we could simply add 0.5 seven times.

Answer:

Step-by-step explanation:

Here it's given that a 6m ladder is leaned against a house, and the base of ladder is 2m away from the foot of the house. Here I am assuming x to be the height of the house.

Diagram :-

[tex] \begin{picture}(3,3)\setlength{\unitlength}{1cm} \linethickness{.6mm}\put(0,0){\line(1,0){4}}\put(0.01,0){\line(4,3){4}}\put(4,0){\line(0,1){3}}\put(4.3,1){$\bf x $} \put(2,-0.5){$\bf 2m$}\put(1,1.5){$\bf 6m$}\put(.9,0.2){$\bf\theta $}\put(2,4){$\boxed{\sf - RISH4BH }$}\end{picture} [/tex]

Using, Pythagoras theorem ,

[tex]\longrightarrow h^2=p^2+b^2 [/tex]

Substitute,

[tex]\longrightarrow (6m)^2=x^2+(2m)^2[/tex]

Simplify,

[tex]\longrightarrow 36m^2= x^2+4m^2 [/tex]

Subtracting 4m² on both sides,

[tex]\longrightarrow x^2 = 36m^2 -4m^2=32m^2 [/tex]

Put square root on both sides,

[tex]\longrightarrow x =\sqrt{32m^2}[/tex]

Simplify,

[tex]\longrightarrow \underline{\underline{ x = 5.65\ m}}[/tex]

Again in order to find out the angle of elevation,

[tex]\longrightarrow cos\theta =\dfrac{b}{h} [/tex]

Substitute,

[tex]\longrightarrow cos\theta =\dfrac{2m}{6m}[/tex]

Simplify,

[tex]\longrightarrow cos\theta =\dfrac{1}{3} [/tex]

Take cos inverse both sides,

[tex]\longrightarrow \underline{\underline{\theta =cos^{-1}\bigg(\dfrac{1}{3}\bigg)}}[/tex]

The length of the wall is 5.66m and the angle of elevation is 70.56°

Data;

To calculate the length of the wall or side of the house, we have to use Pythagorean theorem which is given as

[tex]x^2 = y^2 + z^2[/tex]

Let's substitute the values and solve for the length of the wall

[tex]x^2 = y^2 + z^2 \\6^2 = 2^2 + z^2 \\36 = 4 - z^2\\z^2 = 36 - 4\\z^2 = 32\\z = \sqrt{32} \\z = 5.66m[/tex]

The length of the wall is 5.66m.

To calculate the angle of elevation, we can use trigonometric ratio SOHCAHTOA

since we have the value of all the sides, we can decide to use any of the ratios.

I will use sine angle to solve for the angle of elevation.

[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin \theta = \frac{5.66}{6} \\sin \theta = 0.943\\\theta = sin^-^1 (0.943)\\\theta = 70.56^0[/tex]

The angle of elevation is 70.56°
