find two numbers if their sum is 7.2 and their difference is 2.7

Answer:

16x² - 24x + 9

Step-by-step explanation:

One side = (8x-6)÷4

One side = 2x - 3/2

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

Open the brackets

2x(2x-3/2) - 3/2(2x-3/2)

= 16x² - 24x + 9

Answer:

The distance is √58

or 7.61577...

Step-by-step explanation:

If you draw a right triangle where the given line is the hypotenuse you can use Pythagorean theorem (a²+b²=c²) to find the length.

It would be 7 units tall and 3 units wide.

7²+3²=49+9=58

The distance is √58

The cοmplete equatiοn fοr h(x) is h(x)=4

An expοnential functiοn is a mathematical functiοn οf the fοrm f(x) = a^x, where a is a cοnstant and x is the variable. The cοnstant a is called the base οf the expοnential functiοn, and it is typically a pοsitive real number. When a is greater than 1, the functiοn represents expοnential grοwth, while when a is between 0 and 1, the functiοn represents expοnential decay.

Expοnential functiοns have sοme special prοperties, such as the fact that the rate οf change οf the functiοn is prοpοrtiοnal tο its value. In οther wοrds, the larger the value οf the functiοn, the faster it grοws οr decays. Expοnential functiοns alsο have a hοrizοntal asymptοte at y = 0 when a is between 0 and 1, and nο hοrizοntal asymptοte when a is greater than 1.

Expοnential functiοns are widely used in mathematics, science, ecοnοmics, and engineering tο mοdel phenοmena that exhibit expοnential grοwth οr decay, such as pοpulatiοn grοwth, radiοactive decay, and cοmpοund interest. They are alsο used in prοbability theοry tο mοdel the distributiοn οf randοm variables, such as the expοnential distributiοn.

Tο cοmplete the equatiοn fοr h(x), we need tο find the values οf a and b in the expοnential functiοn that cοrrespοnd tο the given table οf values:

x | h(x)

0 | 10

1  | 10

2 | 10

3 | 4

4 | 4

5 | 4

Since the value of h(x) is constant (equal to 10) for x = 0, 1, and 2, we know that  [tex]b^0 = b^1 = b^2 = 1[/tex], which implies that b = 1.

Substituting b = 1 into the exponential function, we have:

[tex]h(x) = a * 1^x = a[/tex]

To find the value of a, we can use any of the given values of h(x) for which x > 2. For example, when x = 3, we have:

h(3) = 4 = a

Therefore, the complete equation for h(x) is:

[tex]h(x) = 4 * 1^x = 4[/tex]

Step-by-step explanation:

Roberto wrote a sentence that describes an equation. Half of a number is 45. Which choice shows Roberto’s equation and its solution? 2 x = 45; x = 90 StartFraction 45 Over 2 EndFraction = x; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 90.

(1/2)x = 45

x = 45 * 2

x = 90

--------------------

check

90 : 2 = 45

the answer is good

Your answer is  [tex}x = 45 * 2x = 90[/tex]

x = 45 * 2

x = 90

90 : 2 = 45

Answer:

ok so first we know that 1/3 of a hour is 20 minutes since

60*1/3=20

so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15

20*15=300

300 minutes or 5 hours

Hope This Helps!!!

Answer:

5 Hour

Step-by-step explanation:

For 1/15 of lawn it takes = 1/3

So, for entire lawn it will take = 1/3 * 15 = 5

Answer:

vertex = (- 3, 1 )

Step-by-step explanation:

given a quadratic in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the vertex is

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

f(x) = x² + 6x + 10 ← is in standard form

with a = 1, b = 6 , then

x = - [tex]\frac{6}{2}[/tex] = - 3

substitute x = - 3 into f(x) for corresponding y- coordinate

f(- 3) = (- 3)² + 6(- 3) + 10 = 9 - 18 + 10 = 1

vertex = (- 3, 1 )

Given the volume of the cone to be 60π, the radius, height, and diameter of the cone would be:

Volume of a Cone = 1/3 × πr²h

Given that the volume of the cone is: 60π

Thus:

Thus:

Volume = 1/3 × π × 6² × 5

Volume = 1/3 × π × 6² × 5 = 60π

Answer:

$13.70

Step-by-step explanation:

20 - 2.25 x 2.8

20-16.3 = 13.7

===========================================

Work Shown:

AC/QS = BC/RS

4/10 = m/15

4*15 = 10*m

60 = 10m

10m = 60

m = 60/10

m = 6

The first equation is possible because the triangles are similar. The horizontal sides AC and QS form the ratio AC/QS. This is equal to the ratio of the diagonal sides BC/RS since similar triangles have their sides in proportion.

After the equation is set up, we cross multiply and then solve for m.
