Answer:

The number is 1.2 and the algebraic equation is 10x=12

Step-by-step explanation:

Since the product of a number and ten is 12, we can express it as the algebraic equation x*10=12, where x is any number.

x*10=12

10x=12

x=12/10

x=1.2

Therefore, The number is 1.2

Answer: z = [tex]\sqrt{10}[/tex]

Step-by-step explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

[tex]\frac{a}{x} =\frac{x}{b}[/tex]

You can use 5 as a and 2 as b to complete the proportion:

[tex]\frac{5}{x} =\frac{x}{2}[/tex]

Next, to solve:

Step 1: Cross-multiply.

[tex]\frac{5}{z} =\frac{z}{2}[/tex]

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z

Answer: f(x) = 3x^(2)-2x+1

f(x) = 3x^(2)-2x+1 = y-intercept (0, 1).

g(x) = -10x^(2)+50x = y-intercept (0, 0).

As we see, the first equation (f(x) = 3x^(2)-2x+1) has a y-intercept of (0, 1), while the other equation (g(x) = -10x^(2)+50x) has a y-intercept of (0, 0). This means that the quadratic equation that has the greatest y-intercept is f(x) = 3x^(2)-2x+1, which is (0, 1).

Step-by-step explanation:

Answer:

144 square feet

Step-by-step explanation:

First. the base is 6 by 6, meaning the surface area of it is 36 square feet. Then, we do a single triangle, whose area is (6*9)/2, or 27. 27*4 is 108, so the answer will be 108+36=144.

Answer is: 144 square feet

Have a great day! :)

Answer:

Addition Property of Equality

Step-by-step explanation:

Addition Property of Equality.

The addition property of equality justifies the work done in Line 3. This is because it essentially states that if you add something to one side of an equation, you must add it to the other side as well. In this case, we are adding 22 to both sides of the equation, therefore we are making use of the Addition Property of Equality.

Answer:

x=3.42

Step-by-step explanation:

[tex] \sin(20) = \frac{x}{10} [/tex]

[tex]x = 10 \sin(20) = 3.42[/tex]

Answer:

x = 3.420 (to the nearest hundredth)

Step-by-step explanation:

Trig ratios:

sin(x) = O/H

cos(x) = A/H

tan(x) = O/A

where x is the angle, O = side opposite the angle, A = side adjacent to the angle, H = hypotenuse

We have been given:

angle = 20°

opposite side to angle = x

hypotenuse = 10

Therefore, we should use sin(x) = O/H

Substituting the above values into the trig ratio:

⇒  sin(20) = x/10

⇒  x = 10 sin(20)

⇒  x = 3.420 (to the nearest hundredth)

Answer: How to Find the Distance between Two Points on a Graph

1

Take the coordinates of two points you want to find the distance between.

2

Know the distance formula. This formula finds the length of a line that stretches between two...

3

Find the horizontal and vertical distance between the points.

4

Square both values. This means that you will square the x-axis distance (x2 - x1).

Step-by-step explanation:

Step-by-step explanation:

the distance between 2 points is the Hypotenuse of a right-angled triangle with the legs being the x coordinate difference and the y coordinate difference.

so, Pythagoras applies.

c² = a² + b²

distance² = (2 - -7)² + (11 - 9)² = 9² + 2² = 81 + 4 = 85

distance = sqrt(85) = 9.219544457... ≈ 9.2

The distance between the points A(2,11) and B(−7,9) is d = √85.

There are two points (a, b) and (c, d) then the distance between two points is

d= √(c -a)² + (d-b)²

We have the points A(2, 11) and B(-7, 9).

Using the Distance Formula

d = √(-7-2)² + (9-11)²

d= √(-9)² + (-2)²

d= √81 + 4

d = √85

Thus, the distance between points is √85 unit.

Answer:

When l = 4m , breadth is 8m

When l = 8m , breadth is 4m .

Step-by-step explanation:

Here it is given that the area of a rectangular patch is 32m² . If we assume length to be l and breadth to be b , then ;

[tex]\longrightarrow Area_{rectangle}=length\times breadth\\ [/tex]

[tex]\longrightarrow 32m^2 = lb \dots (i) [/tex]

Again , it's given that the perimeter is 24m .We know that perimeter of a rectangle is ,

[tex]\longrightarrow Perimeter = 2(l+b)\\ [/tex]

[tex]\longrightarrow 24 = 2( l +b)\\ [/tex]

[tex]\longrightarrow l + b = 12\dots (ii) [/tex]

From equation (i) and (ii) , we have ;

[tex]\longrightarrow l + \dfrac{32}{l}=12\\\\\longrightarrow \dfrac{l^2+32}{12}=1\\\\\longrightarrow l^2+32=12l \\\\\longrightarrow l^2-12l +32=0\\\\\longrightarrow l^2-4l -8l +32=0 \\\\\longrightarrow l( l -4) -8(l-4)=0\\\\\longrightarrow(l-4)(l-8)=0 \\\\\longrightarrow \underline{\underline{ l = 4,8}} [/tex]

Therefore , we can find breadth as,

[tex]\longrightarrow l + b =12\\\\\longrightarrow b = 12 - l \\\\\longrightarrow b = 12-8, 12-4\\\\\longrightarrow \underline{\underline{b = 4,8}}[/tex]

40/10  [4 meters/sec]

Step-by-step explanation:

Watch for what the units are telling us.  The number that is being requested  

is speed in units of meters/sec.  We are given 40 meters and 10 seconds.  If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

The polynomial  [tex]3x^5 + 7x^6 + 11x^7 - 12x - 10[/tex] is in standard form if the exponents are arranged in decreasing order.

Polynomial is an algebraic expression with one or more terms. For example :[tex]2x^3+6x^4+x^2+x+2[/tex]. In this example and in your exercise the exponents of the terms are not arranged in order.

Um polynomial is in Standard Form when the exponents of the terms are in decreasing order. See more details below.

[tex]2x^3+6x^4+x^2+x+2[/tex]is not in standard form because the exponents are not written in decreasing order.

[tex]6x^4+2x^3++x^2+x+2[/tex] is in standard form because the exponents are written in decreasing order.
