Step-by-step explanation:

The point of intersection of the altitude of a triangle is called orthocentre.

Answer:

X = 0, Y= -2

Step-by-step explanation:

Compare the x and y coordinate values

3x + 2y =-4_______(1)

2x - y = 2 ________(2)

Multiply the (2) with 2

4x - 2y = 4

and add the new equation to (1)

3x + 2y =-4

4x - 2y = 4

____________

7x = 0

X = 0

Substitute x value into (1)

3 *0 + 2y = -4

0 + 2y =-4

2y =-4

Y= -2

Answer:

[tex]4^m[/tex]

Step-by-step explanation:

When you exponent an exponent, you multiply the powers together.

When you divide exponents, you subtract the powers.

Step 1: Convert to same base

log₄64 = 3

Step 2: Rewrite equation

[tex]\frac{(4^3)^{0.5m}}{4^{0.5m}}[/tex]

Step 3: Simplify

[tex]\frac{4^{1.5m}}{4^{0.5m}}[/tex]

Step 4: Simplify

[tex]4^m[/tex]

Answer:

m∠C  =  60°

Step-by-step explanation:

we know that sum of angles of a traingle is 18 degrees.

given

m∠A = 60°+α,

m∠B = 60°−α

we have to find  m∠C

m∠A + m∠B +  m∠C = 180

60°+α +  60° - α +m∠C = 180

+α and -α gets cancelled

120°+m∠C = 180

=> m∠C  =  180° -  120° =  60°

Thus, measure of angle c is  60°.

Answer:

x = 6, y = 1

Step-by-step explanation:

-5x+10y = -20

5x-4y = 26

Adding both equations

=> -5x+10y+5x-4y = -20+26

=> 10y - 4y = 6

=> 6y = 6

Dividing both sides by 6

=> y = 1

Putting y = 1 in the first equation

=> -5x+10(1) = -20

=> -5x = -20-10

=> -5x = -30

Dividing both sides by -5

=> x = 6

Answer:

Step-by-step explanation:

Using the elemination method,

-5x + 10y = - 20

5x - 4y = 26

_____________

6y = 6

divide both sides of the equation by 6

6y/6 = 6/6

y = 1 --------> equation (i)

again,

Finding the value of X,

plugging the value of y from equation (i)

-5x + 10y = -20

or, -5x + 10*1 = -20

or, -5x + 10 = -20

or, -5x = -20-10

or, -5x = -30

or, x = -30/-5

X = 6

Hope this helps....

Good luck on your assignment..

Answer:

b,d,e,f and g

Step-by-step explanation:

A binomial is a polynomial with 2 terms

● a has only one term (15)

● b has two terms 15x and 2 so it is a binomial

● c has only one term so it's not a binomial

● d has two terms 512v^5+ 99w^5

● e has also two terms -6y^2 and (-79)x

● f= 2(3x+4) = 6x+8 so f has two terms then it's a binomial

● g has also two terms

Answer:

when y=1 then x=0.5

Step-by-step explanation:

The graph is provided.

The equation y=4x-1 can be graphed by first graphing the -1 which is the y-intercept in the y=mx+b form. 4=m that is our slope. you can find the lines second point by moving 4 up and 1 to the right. rise/run =4/1. So when you move 4 up and 1 right you get another point on the line (1,3).

You can find out x=0.5 when y=1 by just tracing your finger over the graph and the point when y equals 1 the line intercepts x=0.5. Another screenshot is given.

Answer:

C = 2πr = 2 * 3.14 * 20 = 125.6

Answer:

[tex]\huge\boxed{C\approx125.6}[/tex]

Step-by-step explanation:

The formula of a circumference of a circle:

[tex]C=d\pi=2\pi r[/tex]

d - diameter

r - radius

We have the radius r = 20.

Substitute:

[tex]C=2\pi(20)=40\pi[/tex]

use π ≈ 3.14

[tex]C\approx(40)(3.14)=125.6[/tex]

Answer:

d

Step-by-step explanation:

At 7 o' clock the minute hand is at 12 and the hour hand at 7

There is 360° in a complete revolution, thus between 7 and 12

angle = [tex]\frac{7}{12}[/tex] × 360° = 7 × 30° = 210° → d

Answer:

Option D) Angle at 7 o'clock = 210 degrees

Step-by-step explanation:

The whole clock = 360 degrees

Every 1 hour = 360/12

Every 1 hour = 30 degrees

Angle at 7 o'clock = 30*7

Angle at 7 o'clock = 210 degrees

Answer: 1,914

Step-by-step explanation:

first we take down the information given to us

For 92% confidence, z = 1.75

Error of margin  E = 2% = 0.02

Since no estimate of population proportion has been given, we will assume:

p = q = 0.50

Hence,  

Sample size required n

n = ( z/E)² × p × q

n = ( 1.75/0.02)² × 0.5 × 0.5

n = (87.5)² × 0.5 ×0.5

n =  1914

Answer:

Please refer to the attached image for the graph of given function.

Step-by-step explanation:

Given the equation:

[tex]-x^{2} +4x+12[/tex]

Let us rewrite by letting it equal to [tex]y[/tex].

[tex]y=-x^{2} +4x+12[/tex]

Now, we can see that it is a quadratic equation and it is known that a quadratic equation has a graph of parabola.

Let us compare the given equation with standard quadratic equation:

[tex]y=ax^{2} +bx+c[/tex]

we get:

[tex]a = -1\\b = 4\\c = 12[/tex]

Coefficient of [tex]x^{2}[/tex] is negative 1, so the parabola will open downwards.

Axis of symmetry: It is the line which will divide the parabola in two equal congruent halves.

Formula for axis of symmetry is:

[tex]x = -\dfrac{b}{2a}[/tex]

[tex]x = -\dfrac{4}{2(-1)}\\\Rightarrow x=2[/tex]

It is shown as dotted line in the image attached in the answer area.

Axis of symmetry will also contain the vertex of the parabola.

It is a downward parabola so vertex will be the highest point on this parabola.

Putting x = 2 in the equation of parabola:

[tex]y=-2^{2} +4\times 2+12\\\Rightarrow y =16[/tex]

So, vertex will be at P(2, 16).

Now, let us find points of parabola to sketch graph:

put x = 0, [tex]y=-0^{2} +4\times 0+12=12[/tex]

Another point is Y(0,12)

Now, let us put y = 0, it will give us two points because the equation is quadratic in x.

[tex]0=-x^{2} +4x+12\\\Rightarrow -x^{2} +6x-2x+12=0\\\Rightarrow -x(x -6)-2(x-6)=0\\\Rightarrow (-x-2)(x-6)=0\\\Rightarrow x = -2, 6[/tex]

So, other two points are X1(-2, 0) and X2(6,0).

If we plot the points P, Y, X1 and X2 we get a graph as attached in the image in answer area.

Answer:

Option (3).(Bottom left)

Step-by-step explanation:

Formula for the exponential growth is,

h(x) = [tex]a(1+\frac{r}{100} )^{t}[/tex]

where r = rate of exponential growth

a = initial amount

t = duration or time

Option (1) (Top left)

h(t) = [tex](1+0.18)^{\frac{t}{6}}[/tex]

     = [tex](1+\frac{18}{100})^t[/tex]

Rate of exponential growth will be,

r = 18%

Option (2) (Top right)

k(t) = [tex](\frac{3}{8})^t[/tex]

     = [tex](1-\frac{5}{8})^t[/tex]

     = [tex](1-0.625)^t[/tex]

     = [tex](1-\frac{62.5}{100})^t[/tex]

r = -62.5%

This function shows the exponential decay rate of 62.5%.

Option (3) (Bottom left)

f(t) = [tex]1.36^t[/tex]

    = [tex](1+0.36)^t[/tex]

    = [tex](1+\frac{36}{100})^t[/tex]

r = 36%

Option (4) (Bottom right)

g(t) = [tex]0.86^t[/tex]

     = [tex](1-0.14)^t[/tex]

     = [tex](1-\frac{14}{100})^t[/tex]

r = -14%

This function shows the decay rate of 14%.

Therefore, Option (3). (Bottom left) shows the greatest exponential growth.

Decimal Form:

j  =  1.79583152  …  ,  −  7.79583152

Answer:

Step-by-step explanation:

8d + 4 = 5d + 28

Group like terms

That's

8d - 5d = 28 - 4

3d = 24

Divide both sides by 3

d = 8

[tex] \frac{7(7g + 8)}{4} = 38.5[/tex]

Cross multiply

we have

7(7g + 8) = 38.5(4)

49g + 56 = 154

49g = 154 - 56

49g = 98

Divide both sides by 49

g = 2

Answer:

260

Step-by-step explanation:

a= 17

common difference (d ) = 19-17 = 2

a+(n-1)d = 35

17+(n-1)2 = 35

(n-1)2 = 35-17

n-1 = 18/2

n-1= 9

n = 9+1 = 10

Sum of the arithmetic sequence

= n/2[2a+(n-1)d]

= 10/2 [ 2(17)+ (10-1)2]

= 5(34+18)

= 5× 52

=260

Answer:

260

Step-by-step explanation:

Given the first and last terms in the sequence , calculate the sum using

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] (a + l)

where a is the first term and l the last term

Here a = 17 and l = 35

To calculate the number of terms use the n th term formula

[tex]a_{n}[/tex] = a + (n - 1)d

where d is the common difference

a = 17 and d = 19 - 17 = 2 and [tex]a_{n}[/tex] = 35, thus

17 + 2(n - 1) = 35 ( subtract 17 from both sides )

2(n - 1) = 18 ( divide both sides by 2 )

n - 1 = 9 ( add 1 to both sides )

n = 10

Hence

[tex]S_{10}[/tex] = 5(17 + 35) = 5 × 52 = 260

Answer:

To divide it into the above ratio we must first find the total parts which is

3 + 4 = 7

First part is

3/7 × 35

= 3 × 5

Second part is

4/7 × 35

= 4 × 5

The following ages combination is possible -

[A] = 17 and [B] = 6

or

[A] = 6 and [B] = 17

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is sum of the ages of A and B as 23 years and their product is 102 years.

Assume that the age of A is [x] years and of B is [y] years. So, we can write -

x + y = 23

xy = 102

Refer to the graph attached. It shows two points of intersection as -

(17, 6)  and  (6, 17).

Therefore, the following ages combination is possible -
