Response:

  • x - 5 at 2x + 3

Detailed explanation:

Given

  • Area ng rektanggulo = 2x^2 - 7x - 15

Layunin

  • Mga sukat ng rektanggulo

Sagot

Dahil ang lugar ay produkto ng mga gilid, subukan nating i-factor ang ibinigay:

  • 2x^2 - 7x - 15=
  • 2x^2 - 10x + 3x - 15 =
  • 2x(x - 5) + 3(x - 5) =
  • (x - 5)(2x + 3)

Kaya ang mga sukat ay:

  • x - 5 at 2x + 3

A rectangular prism must have a base with an area of no more than 27 square meters. The width of the base must be 9 meters less
Leona [12618]

Answer:

The upper limit for the height of the prism is 12\ m

Step-by-step explanation:

Let

x------> represent the height of the prism

It is known that

the area of the base of the prism must not exceed

A=L*W

A\leq 27\ m^{2}

thus

L*W\leq 27 -------> inequality A

W=x-9 ------> equation B

L=W+6 -----> equation C

Insert equation B into equation C

L=(x-9)+6

L=x-3 ------> equation D

Substituting equations B and D into inequality A

(x-3)*(x-9)\leq 27-------> using a graphing tool to solve the inequality

The resultant solution for x lies in the interval---------->[0,12]

consult the attached figure

but bear in mind that

The width of the base must be 9 meters shorter than the height of the prism

thus

the solution for x is confined to the interval ------> (9,12]

The maximum height of the prism equals 12\ m

On a coordinate plane, 2 exponential fuctions are shown. Function f (x) decreases from quadrant 2 into quadrant 1 and approaches
Zina [12379]

Answer:

g(x)=6(3)^x

Step-by-step explanation:

We are provided with the information that

f(x)=6(\frac{1}{3})^x

Function f is decreasing as it moves from quadrant 2 to quadrant 1, tending towards y=0

It intersects the y-axis at the point (0,6) and goes through (1,2).

Function g(x) also approaches y=0 in quadrant 2, but increases in quadrant 1.

It passes through (-1,2) and crosses the y-axis at (0,6).

Reflection across y-axis:

The transformation rule is identified as

(x,y)\rightarrow (-x,y)

Applying this rule, we derive

g(x)=6(\frac{1}{3})^{-x}=6(3)^x

Then, by substituting

x^{-a}=\frac{1}{x^a}

for x=-1

g(-1)=6\times (\frac{1}{3})=2

for x=0

g(0)=6

Consequently,g(x)=6(3)^x holds true.

In a circle, an arc 60 centimeters long subtends an angle of 5 radians. What is the radius of the circle?
Inessa [12570]
Got it!
There are 2π radians in a complete circle.

Now, let's calculate the circumference.
5/2π = 60/circumference.
Next, solve for the circumference.
By multiplying both sides by 2π, we have: 5 * circumference = 120π.
Now divide both sides by 5, and we find: circumference = 24π.

Using the formula c = 2πr,
we set 24π = 2πr.
Dividing both sides by 2π gives us r = 12. Thus, the radius measures 12cm.

A building has an entry the shape of a parabolic arch 84 ft high and 42 ft wide at the base, as shown below. A parabola opening
lawyer [12517]
Since this parabola intersects the center, its formula is:

y = ax². Given that it opens downward, the coefficient a must be negative.

Thus, the equation can be expressed as:

y = - ax², with the axis of symmetry located at x = 0.

The height measures 84 ft when the parabola's opening is 42 ft wide.
This indicates that for the height y, the corresponding x-values are +21 and -21 (due to symmetry).
To find a, let's substitute y and x with their respective values:

y = - ax²

84 = - a(21)²

84 = - a(441), leading to a = - 84/441 ↔ a = - 4/21.

Therefore, the final equation is: y = -4/21 x².

A 6 inch-tall plant grew 3/4 of an inch week and twice as much the following week. How tall is the plant now?
babunello [11817]
8.25 inches after multiplying the 3/4 by 2, and adding that to the previous 3/4, gives you the final height of the plant.
