Triangle abc is an isosceles right triangle. What is the measure of one base angle? 30ş 45ş 60ş 90ş.

Step-by-step explanation:

I am not sure I understand the numbers in the description, but I assume you meant that

the baseline is x/2 meter,

the height to the baseline is also x/2 meter.

the area is 32 m².

the area of a triangle is

baseline × height / 2.

so, here we have

32 = x/2 × x/2 / 2 = x²/4 / 2 = x²/8

x² = 32×8 = 256

x = 16 m

so the base and the height are both 16/2 = 8 m long.

The quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

The general form of the quadratic equation is given by;

[tex]\rm ax^2+bx+c=0[/tex]

Where; a, b, and c are the constants.

x;   0       1         2        3          4         5

y;  2.82  3. 29  3. 46  3. 33   2. 88  2. 24

From the table when the value of x = 0 the value of y is 2.82.

Then,

[tex]\rm y=ax^2+bx+c\\\\x=0\\\\2.82=a0^2+b(0)+c\\\\c=2.82[/tex]

From the table when the value of x = 3 the value of y is 3.33.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.82=a(3)^2+b(3)+c\\\\9a+3b+2.82=2.82\\\\9a=-3b\\\\b=-3a\\\\[/tex]

From the table when the value of x = 5 the value of y is 2.24.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.24=a(5)^2+(-3a)(5)+c\\\\25a-15a+2.82=2.24\\\\40a=2.24-2.82\\\\10a=-0.68\\\\a= \dfrac{-0.68}{10}\\\\a=-0.143[/tex]

And the value of b is;

[tex]\rm b=3a\\\\b=3(-0.14)\\\\b=0.59[/tex]

Therefore,

The quadratic regression equation for this data set is;

[tex]\rm y=ax^2+bx+c\\\\y=-0.143x^2+0.59x+2.82\\\\[/tex]

Hence, the quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

Answer:

xy=4 AND

y=7x^4

Step-by-step explanation:

B. xy = 4 is a hyperbola, which is a two-piece curve with an asymptote.

C. y = 7x^4

is a quartic, also a curve.

You can tell the other equations ARE linear, because they have no exponent on the variables. (If you solve the "xy" equation for y, the x ends up on the bottom of a rational expression--not linear)

[tex]\huge\text{Solution:}[/tex]

Hi there!

We are given the slope of the line and its y-intercept.

So, we can easily identify the equation of the line.

The equation of the line is usually written in slope-intercept form.

Slope-Intercept Form looks like this:

[tex]\fbox{y=mx+b}[/tex]

Where m is the slope and b is the y-intercept.

In this case, the slope is -4.4, and the y-intercept is 6.8, so all we need to do is plug in -4.4 instead of m and 6.8 instead of b:

[tex]\longmapsto[/tex][tex]\fbox{y=-4.4x+6.8}[/tex] (Answer)

Step-by-step explanation:

given expression → x/y

we know,

x = 3 and y = 27

according to expression

3/27 → 1/9

therefore 1/9 is the answer.

Hope this answer helps you!

Answer:

1/9

Step-by-step explanation:

1. First, let's plug in the values of x and y.

2. Next, we have to simplify and find the greatest common factor between 3 and 27.

3. As you can see, 3 is the GCF of 3 and 27, so we divide both 3 and 27 by 3.

Therefore, the answer is 1/9!

A triangle is isosceles triangle when the two sides and two angle of the triangle in equal in measure.

The approximate total area of the plastic triangles on the spinner is 7.7 squared centimetre.

A triangle is isosceles triangle when the two sides and two angle of the triangle in equal in measure.

The area of the isosceles triangle is given as,

[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }[/tex]

Here, [tex]a[/tex] is the measure of equal sides and [tex]b[/tex] is the measure of third side.

Given information-

The arrows of board game are congruent isosceles triangles connected at their bases.

isosceles triangles are connected at their bases.

The base of each triangle measures 2 centimetres

The perimeter of each triangle is 10 centimetres.

The perimeter of a triangle is sum of all its sides.

As the given triangle is isosceles triangle. Thus both the sides of the triangle should be equal.

Suppose the equal sides is x centimetres. The measure of third side is given which is equal to 2 centimetres. Thus,

[tex]x+x+2=10\\2x=10-2\\2x=8\\x=\dfrac{8}{2} \\x=4[/tex]

Hence the length of the equal sides of the isosceles triangle is 4 cm.

Using the above formula as,

[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }\\A=\dfrac{1}{2}\times 2\times \sqrt{4^2-\dfrac{2^2}{4} }\\A= \sqrt{16-\dfrac{4}{4} }\\A=3.871[/tex]

Hence the area of one plastic arrow triangle is 3.71 square centimetre. The approximate total area of the plastic triangles on the spinner is twice of it. Thus,

[tex]A=3.71\times2\\A=7.7[/tex]

Thus the approximate total area of the plastic triangles on the spinner is 7.7 squared centimetre.

Step-by-step explanation:

Pretty sure it equals 360 degress overall so 360 -313 = ^^^^^^^^^^^^

Answer:

no

Step-by-step explanation:

using the values of the ordered pair in the first equating we get :

2 = 3×5 - 13 = 15 - 13 = 2

that fits.

but when using them in the second equation we get :

4×5 - 3×2 = 17

20 - 6 = 17

14 = 17

and that is wrong.

that means the point (5, 2) is not on the second line, so the point cannot be the crossing point (= solution, where both equations deliver the same result) of both lines.

FYI

we would solve the system by using the first equality directly in the second equation :

4x - 3(3x - 13) = 17

4x - 9x + 39 = 17

-5x = - 22

5x = 22

x = 22/5 = 4.4

and y is then

y = 3×4.4 - 13 = 13.2 - 13 = 0.2

the actual solution of the system is therefore

(4.4, 0.2)

Answer:

10,000 cm² in 1 m²

1,000,000 cm³ in 1 m³

Step-by-step explanation:

There are 100 cm in 1 m

Therefore, to find how many square cms are in 1 square meter, we need to square 100:  100² = 100 x 100 = 10,000

Therefore, there are 10,000 cm² in 1 m²

Therefore, to find how many cubic cms are in 1 square meter, we need to cube 100:  100³ = 100 x 100 x 100 = 1,000,000

Therefore, there are 1,000,000 cm³ in 1 m³

Answer:

1m^2 = 10,000cm^2 (10 thousand square centimeters)

1m^3 = 1,000,000cm^3 (1 million cubic centimeters)

Step-by-step explanation:

x^2 is the same as x × x

There are 100 sm in a meter, so in this case x = 100

100^2 = 100 × 100 = 10,000

x^3 is the same as x × x × x

100^3 = 100 × 100 × 100 = 1,000,000

Answer:

y=5 x=110

Step-by-step explanation:

Answer:

x = 10 , y = 5

Step-by-step explanation:

It is given that x = 2y. Plug in 2y for x in the first equation, and then solve for the variable, y:

-4x  + 11y = 15

x = 2y

-4(2y) + 11y = 15

First, multiply, then combine like terms:

(-4 * 2y) + 11y = 15

(-8y) + 11y = 15

11y - 8y = 15

3y = 15

Isolate the variable, y. Divide 3 from both sides of the equations:

(3y)/3 = (15)/3

y = 15/3 = 5

Plug in 5 for y in one of the equations to solve for x:

x = 2y

x = 2(5)

x = 10

x = 10 , y = 5
