C. -x3+5x2+7√x-1
D. 2x-2+5x-3
E. 5.3x2+3x-2/x+6​

Answer:

The coordinate of the midpoint of AB is (1.5, 3).

Step-by-step explanation:

The midpoint of AB is the point that is the same distance between both points A and B. In order to find the midpoint, add the x and y values of points A and B respectively, and divide the sum by 2 to find the midpoint of AB. [tex]\frac{1+2}{2} = 1.5[/tex], so the x value of the midpoint is 1.5. [tex]\frac{0+6}{2} = 3[/tex], so the y value of the midpoint is 3. You'll get that the coordinate of the midpoint of AB is (1.5, 3).

Answer:

A) 7.8

Step-by-step explanation:

The side lengths of the triangle are 5 units and 6 units.

Using the Pythagorean Theorem, a²+b²=c², we can find the hypotenuse, c, given side lengths a and b:

a²+b²=c²

5²+6²=c²

25+36=c²

61=c²

√61=c

7.81≈c

Therefore, the hypotenuse is about 7.81 units, making A the closest choice.

Answer:

lesser # is 5

other # is 12

Step-by-step explanation:

x = lesser #

x + y = 17

x = 2/3y - 3

let 'y' = 17-x

substitute 'y':

x = 2/3(17-x) - 3

x = 34/3 - 2x/3 - 9/3

add 2x/3 to each side to get:

5x/3 = 25/3

multiply each side by 3/5 to get:

x = 25/5 or 5

5 + y = 17

y = 12

Answer:

The solution set is {-2/9, 4).

Step-by-step explanation:

(x + 3)/(x-2)  - (1-x)/x = 17/4

Multiply through by the LCD ( = 4x(x - 2):

(x + 3)4x - 4(1 - x)(x - 2) = 17x(x - 2)

4x^2 + 12x - 4(x - 2 - x^2 + 2x) - 17x^2 + 34x = 0

4x^2 + 12x - 4x + 8 + 4x^2 - 8x - 17x^2 + 34x = 0

-9x^2 + 34x + 8 = 0

We need 2 numbers  whose product = -72 ( -9 * 8) and whose sum is 34.

These are +36 and -2, so we write:

-9x^2 + 36x - 2x + 8 = 0

-9x(x - 4) - 2(x - 4) = 0

(-9x + 2)(x - 4) = 0

x = -2/9, 4.

Using Pythagorean's theorem we can see that the distance is 13.6 miles.

You can think of this as a right triangle.

The two distances that you drive are the legs of it, and the distance betwen the initial point and the final point is the hypotenuse of the triangle.

Then we can use Pythagorean's theorem to find the hypotenuse, we know that:

H^2 = A^2 + B^2

H = √(A^2 + B^2)

Where:

A = 8 miles.

B = 11 miles

REplacing that we will get:

H = √( (8mi)^2 + (11mi)^2)

H = 13.6 miles.

Answer:

108$

Step-by-step explanation:

Answer:

x = 40

smaller angle is 80

larger angle is 100

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees

Hence, x + 40 + 3x - 20 = 180

( note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

x + 40 + 3x - 20 = 180

step 1 combine like terms

x + 3x = 4x

40 - 20 = 20

we now have 4x + 20 = 180

step 2 subtract 20 from each side

180 - 20 = 160

we now have 160 = 4x

step 3 divide each side by 4

160 / 4 = 40

4x / 4 = x

we're left with x = 40

we now plug in 40 for x to find the value of each angle

x + 40

* substitute 40 for x *

40 + 40 = 80

3x - 20

* substitute 40 for x *

3 ( 40 ) - 20

3 * 40 = 120

120 - 20 = 20

so the larger angle is 100 degrees and the smaller angle is 80 degrees

Answer:

C: 95.9%

Step-by-step explanation:

To find this, we shall be using the cumulative binomial probability calculator

As we know, the probability of getting a head or a tail in a throw of a coin is same with a value of 0.5

So, we want to find the probability of getting tails 50 times or fewer which means the probability of getting at most 50 tails

So we have the parameters as follows;

P( x ≤ 50)

n = number of trials = 85

p = probability of success = 0.5

r = number of success = 50

Using the parameters in the cumulative binomial probability calculator, we have the value as ;

0.9589 = 95.9%

Step-by-step explanation:

From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,

Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.

Slope :-

→ m = 3/-1.5

→ m = -2

Answer:

Slope -[tex]\\\frac{1}{2}[/tex]

Y intercept 1

Step-by-step explanation:

Answer:

tgα = 9/8

secα = 10/8

cscα = 10/9

ctgα = 8/9

Step-by-step explanation:

PAra resolver esto, es necesario conocer como se determinan las funciones trigonométricas en general. Ya tenemos el valor del seno y coseno de un angulo dado (supongamos un angulo α)

Si senα = 9/10 y cosα = 8/10, para calcular la tangente se aplica la siguiente expresión:

tgα = senα / cosα  (1)

Reemplazando tenemos:

tgα = (9/10) / (8/10)        Aqui se simplifican los 10, y nos queda

Nos quedan 3 funciones, y son las inversas de estas 3 funciones anteriores, y se determinan de la siguiente forma:

secα = 1 / cosα   (2)

cscα = 1 / senα   (3)

ctgα = 1 / tgα = cscα / secα  (4)

Aplicando estas 3 expresiones tenemos:

secα = 1 / (8/10)           Se aplica inversión de numerador y denominador

cscα = 1 / (9/10)

ctgα = 1 / (9/8)

Answer: Never because Aislyn cannot catch up if they make the same amount of money per day.

Step-by-step explanation:

Assume that the day they will have the same amount of money is x.

The amount that Xander will have on that day is:

= 15 + 4x

The amount that Aislyn will have on that day is:

= 10 + 4x

Equate the two fractions:

15 + 4x = 10 + 4x

15 - 10 + 4x = 4x

5 = 4x - 4x

5 = 0x

What this means is that they will never have the same amount of money because they are increasing by the same amount so Aislyn will never catch up.
