Answers

Answer 1

Answer:

r = 5 units

Step-by-step explanation:

One way is to use the Pythag Theroem

12 ^2 + r^2 = (8+r)^2

144 + r^2 = 64 + 16r + r^2

80 = 16 r      r = 5

Find the slope of the line passing through (6, -2) and (-5, 5)

Answers

Answer: [tex]-\frac{7}{11}[/tex]

Step-by-step explanation:

The formula for finding slope is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where [tex](x_{1} ,y_{1} )[/tex] are the coordinates of the first point and [tex](x_{2} ,y_{2} )[/tex] are the coordinates of the second point.

Sub the values in

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\\\frac{5-(-2)}{-5-6} \\[/tex]

Now solve

[tex]\frac{5-(-2)}{-5-6} \\\frac{7}{-11}[/tex]

(6,-2)(-5,5)

Slope:-

Answer:

196 - 49[tex]\pi[/tex]

i hope this helped :)

Step-by-step explanation:

first of all the explaination is to first find the area of the square and then the circle after you have found that you should subtract them and you will get the area of the shaded region.

radius x 2 = the side of the square

7 x 2 = 14

area of square - 14 x 14 = 196 squared

formula of finding the area of the circle - [tex]\pi[/tex]r^2

area of circle - 3.14 x 7 x 7 = 49[tex]\pi[/tex]

so answer simpliefied is 196 - 49[tex]\pi[/tex]

Given circle E with diameter CD and radius EA. AB is tangent to E at A. if AD = 15 and EC = 14, solve for AC.

Answers

Answer:

AC 23.6 units

Step-by-step explanation:

m∠CAD = 90°

CD = 2×14 = 28 , AD = 15

CD² = AD² + AC² ⇒ AC² = CD² - AD²

AC² = 28² - 15² = ( 28 - 15 )( 28 + 15 ) = 13 × 43 = 559

the town of abridge currently has a population of 300,000 each year the population will reduce by 7% how many fewer people will live in abridge in 5 years compared with now give your answer to 3 sf

Answers

Answer:

91,300 to 3 s.f.

Step-by-step explanation:

The population is reduced by a percentage 100-7 = 93%  ( or 0.93) per year.

So after 5 years thatwould be 300,000(0.93)^5

= 208707

that is 300,000 - 208,706

= 91293

= 91,300 to 3 s.f.

Find the length of h. Round to the nearest hundreth.​

Answers

Answer:

Step-by-step explanation:

Assuming this is a parallelogram...

Sine trig ratio

[tex]\sin(\theta)=\sf \dfrac{O}{H}[/tex]

where:

[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse

Let x be the angle in the top left of the parallelogram.

[tex]\implies \sin(x)=\dfrac{0.3}{0.5}=\dfrac35[/tex]

Opposite angles in a parallelogram are congruent.

Therefore, the angle in the bottom right of the parallelogram is also x.

[tex]\implies \sin(x)=\dfrac{h}{0.4}[/tex]

[tex]\textsf{As} \:\sin(x)=\dfrac35[/tex]

[tex]\implies \dfrac35=\dfrac{h}{0.4}[/tex]

[tex]\implies h=\dfrac35 \cdot 0.4=0.24[/tex]

x=y=z

Remember (3,4,5) Pythagorean triplet

Triangle containing y

-1.6, 5/2, -7/8, 0.9, -6/5 from least to greatest

Answers

Answer:

starting with least...

-1.6

-6/5

-7/8

9/10

5/2

...to greatest.

Step-by-step explanation:

start by putting the decimals into fractions:

-1.6 = -8/5

0.9 = 9/10

and then find a common denominator to compare them fairly.

the number that they all end up going into is 40, which will be your common demoninator.

-8/5 (aka -1.6) = -64/40

5/2 = 100/40

-7/8 = -35/40

9/10 (aka 0.9) = 36/40

-6/5 = -48/40

Answers

Answer:

Step-by-step explanation:

This quadratic equation is given in standard form, which is [tex]y= ax^2 +bx+c[/tex]. The x-value of the vertex of a quadratic equation can be found using the given formula. Therefore, we can plug the the numbers given into the formula as such: [tex]x=\frac{24}{2(6)}[/tex]. This can be simplified into 2. Now that we have the x-coordinate, we can plug that back into the equation to find the y-coordinate: [tex]y=6(2)^2-24(2)+30[/tex]. This simplifies to y = 6. Therefore, the vertex of the equation is located at (2,6).

Alejandro will deposit $1,750 in an account that earns 6.5% simple interest every year. His sister Anallency will deposit $1,675 in an account that earns 7.5% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Which sibling will have more money at the end of four years?

Answers

Answer: Anallency

Step-by-step explanation:

First, lets make two equations for both siblings, using the base: SI = P(1 + rt) and CI = P(1 + r/n)^nt

Alejandro = 1750(1 + 0.065[4]) = 1750 + 455 = $2,205

Anallency = 1675(1 + 0.075/1)^4 = $2236.91

After 4 years, Alejandro will have $2,205, and Anallency will have $2236.91

Since $2236.91 > 2,205, Anallency will have more money after 4 years.

Answer:

Anallency will have mor money.

Step-by-step explanation:

Simple Interest:

I = Prt

I = $1750 × 0.065 × 4

I = $455

Total after 4 years: $1750 + $455 = $2205

Compound Interest:

F = P(1 + r/n)^(nt)

F = $1675(1 + 0.075)^(4)

F = $2236.91

Solve the following....
[tex]x+4=3(x-2)[/tex]

Answers

Answer:

x = 5

Step-by-step explanation:

x + 4 = 3(x - 2) ← distribute parenthesis by 3

x + 4 = 3x - 6 ( subtract 3x from both sides )

- 2x + 4 = - 6 ( subtract 4 from both sides )

- 2x = - 10 ( divide both sides by - 2 )

x = 5

Answer:

Solution of equation is 5

Step-by-step explanation:

In the question we have given an equation that is x + 4 = 3 ( x - 2 ) . And we are asked to solve the question that means we have to find the value of x .

Solution : -

[tex] \longrightarrow \quad \: x + 4 = 3(x - 2)[/tex]

Step 1 : Solving parenthesis on right side :

[tex] \longrightarrow \quad \: x + 4 = 3x - 6[/tex]

Step 2 : Subtracting 4 on both sides :

[tex] \longrightarrow \quad \: x + \cancel{4} - \cancel{ 4 }= 3x - 6 - 4[/tex]

On further calculations we get :

[tex] \longrightarrow \quad \: x = 3x - 10[/tex]

Step 3 : Subtracting 3x on both sides :

[tex] \longrightarrow \quad \: x - 3x = \cancel{3x } - \cancel{3x}- 10[/tex]

On further calculations we get :

[tex]\longrightarrow \quad \: - 2x = - 10[/tex]

Step 4 : Dividing both sides by -2 :

[tex]\longrightarrow \quad \: \dfrac{ \cancel{ - 2}x}{ \cancel{ - 2} } = \cancel{\dfrac{ - 10}{ - 2} }[/tex]

On further calculations we get :

[tex]\longrightarrow \quad \: \red{\underline\red{\boxed{ \frak{ x = 5}}}}[/tex]

Therefore , value of x is 5 .

Verifying : -

We are verifying our answer by substituting value of x in given equation. So ,

x + 4 = 3 ( x - 2 )

5 + 4 = 3 ( 5 - 2 )

9 = 3 ( 3 )

9 = 9

L.H.S = R.H.S

Hence, Verified.

Therefore, our answer is correct .

Answers

Answer:

y = 110 degree

x = 70 degree

z = 70 degree

Step-by-step explanation:

Vertical angles are always congruent.

so, the angle with the 110 degree is equal to the angle y.

now we have the measure of y.

as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree

now, to get the measure of angle z,

180 - 110 = angle z

70 = angle z

now we have the measure of angle z

as angle z and angle x are vertical angle, they are congruent.

so angle x = 70

x = 70

z= 70

y = 110
