If g(x) =4x²+2x-24,what is g(2)?
Answer:
-4
Step-by-step explanation:
x is a variable, so to do g(2) you have to write g(x), but substitute 2 in place of x:
g(2) = 4*2² + 2*2 - 24 = 16 + 4 - 24 = -4
10.) The height of a tree trunk is 20 meters, and the base has a diameter of 1 meter. If the tree has the mass
420, what is the density of the tree?
26.27 kgm⁻³
Density is the ratio of mass to volume
Density = Mass / Volume
Let us assume tree is a cylinder,
d= 1
r = d/2 = 0.5 m
h= 20 m
m= 420kg
Volume = π r²h
= 22/7 x o.25 x 20
Density = mass / volume
= 420 / 22/7 x o.25 x 20
= 26.27 kgm⁻³

X(2x-5) = 12
How to solve for x?
Answer:
[tex]x=4,\:x=-\frac{3}{2}[/tex]
Step-by-step explanation:
[tex]x\left(2x-5\right)[/tex]
Apply the distributive law.
[tex]=x\cdot \:2x-x\cdot \:5[/tex]
[tex]=2x^2-5x[/tex]
[tex]2x^2-5x=12[/tex]
Subtract 12 from both sides.
[tex]2x^2-5x-12=12-12[/tex]
[tex]2x^2-5x-12=0[/tex]
Now, apply the quadratic formula.
[tex]x_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-12\right)}}{2\cdot \:2}[/tex]
[tex]x_{1,\:2}=\frac{-\left(-5\right)\pm \:11}{2\cdot \:2}[/tex]

The numeric values for the functions are given as follows:
6 - a) f(-2) = -13.
6 - b) g(4) = 11.
How to find the numeric value of a function?To find the numeric value of a function, we replace each instance of the variable by the desired value.
At item 6a, the function is given by:
f(x) = 5x - 3.
The numeric value at x = -2 is:
f(-2) = 5(-2) - 3 = -10 -3 = -13.
Hence f(-2) = -13.
At item 6b, the function is given by:
g(x) = 0.5x² + 3.
The numeric value at x = 4 is:
g(4) = 0.5(4)² + 3 = 8 + 3 = 11.
Hence g(4) = 11.

The diagram shows a solid triangular prism with a cylindrical hole of radius r cm drilled through it. (i) The ratio of the volume of solid removed : volume of remaining solid is 1 : 6. Find the value of r. Using your answer in part (i), find the total surface area of the solid shown.
The value of the radius r is 9.35 cm.
The dimensions of the triangular prism is 62 cm × 62 cm × 85 cm.
The volume of the prism will be:
Volume = (1/2) × 62 × 62 × 85
Volume = 163370 cm³
Now,
The volume of solid removed: The volume of remaining solid = 1 : 6
Therefore,
The solid removed = ( 1 / 7 ) of the total volume
Solid removed = ( 1 / 7 ) × 163370
Solid removed = 23338.57 cm³ which is the volume of the cylindrical hole.
Now, the volume of the cylinder is:
V = π (r)² h
23338.57 = π (r)² × (85)
23338.57 = (3.142) × (r)² × (85)
23338.57 = 267.1 r²
r² = 87.38
r = √(87.38)
r = 9.35 cm
The surface area of the triangular prism:
A = (1/2) (b) (h)
A = (1/2) (85)(62)
A = 2653 cm²

and danny mowed half as many lawns as jorge. if valeria mowed 16 lawns and
the group mowed a total of 49 lawns in the month, how many did jorge mow?
Jorge mowed 18 lawns.
Let the number of lawns mowed by Jorge =x
So according to the question
Number of lawns mowed by sandra = x/3
Number of lawns mowed by Danny =x/2
Number of lawns mowed by Valeria =16
sum of total lawns mowed = lawns mowed by Jorge + lawns mowed by sandra + lawns mowed by Danny + lawns mowed by Valeria.
[tex]x+\frac{x}{3} +\frac{x}{2} +16=49[/tex]
taking LCM as 6 and solving further we get

The length of a rectangle is seven more than triple the width. if the permiter is 134 inches, find the dimensions
The dimensions of the rectangle that has the perimeter 134 inches is, 52 x 15 inches.
Perimeter of the Rectangle:
Perimeter of the rectangle is defined as the total distance covered by its boundaries or the sides.
The formula for the perimeter of a rectangle,
P = 2 (a + b) units
where
“a” is the length of the rectangle
“b” is the breadth of the rectangle
Given,
The length of a rectangle is seven more than triple the width.
Perimeter of the rectangle = 134inches.
Now we need to find the dimensions of the rectangle.
First, let's define the length of the rectangle as l and the width of the rectangle as w.
Next, we can write the relationship between the length and width as:
l = 3w + 7
We also know the formula for the perimeter of a rectangle is:
=> p = 2(l + w)
So, apply the given values on it,
=> 134 = 2 (3w + 7 + w)
=> 134/2 = 4w + 7
=> 67 = 4w + 7
=> 67 -7 = 4w
=> 4w = 60
=> w = 60/4
=> w = 15
So, the length is,
=> l = 3(15) + 7
=> l = 45 +7
=> l = 52.
Therefore, the dimensions of the rectangle is 52 x 15 inches.

Use prime factorization to determine the greatest common factor of 180 and 504
Answer: 36
Step-by-step explanation:
First you plot down all the factors of 180.*
*180 1, 90 2, 60 3, etc.
Then you do the same for 504.*
*504 1, 252 2, etc.
Once you do that you look through and find the common factor, and you'll find that 180/5=36, and 504/14=36, finding you your GCF.
Cross braces help keep the deck posts straight. Find the measure of each angle.
Angle 5 = 180 - 146 = 34
Angle 6 = 146 since vertical angles are congruent
Angle 7 = 34 since vertical angles are congruent, or you could say 180-146 = 34 again. Any pair of adjacent angles add to 180. All four angles add to 360.

The width of a rectangle is 3 less than its length find the width of the rectangle if its perimeter is 26ft
The width of rectangle is 5 feet.
Let us assume the length of rectangle to be x. So, the width of rectangle will be (x - 3).
Now, as per the known fact, perimeter, length and width of rectangle are related by the formula -
Perimeter = 2 × (length + width)
Keep the values in formula to find the value of width
26 = 2 × (x + x - 3)
Performing addition of variables inside the bracket
26 = 2 × (2x - 3)
Shifting 2 to other side of equation to find the value of x
2x - 3 = [tex]\frac{26}{2}[/tex]
Performing division to find the value of x
2x - 3 = 13
Shifting 3 to other side of equation to find the value of x
2x = 13 + 3
Performing addition to find the value of x
2x = 16
Shifting 2 as denominator to other side of equation to find the value of x
x = [tex]\frac{16}{2}[/tex]
Performing division to find the value of x
x = 8
So, length of rectangle is 8 feet
Width of rectangle = x - 3
Width of rectangle = 8 - 3

A commuter train travels 50 kilometers in 43 minutesWhat is speed in kilometers per hour?
Answer:
70.42 kilometers.
Step-by-step explanation:
43 minutes/60 minutes (1 hour is 60 minutes) = 0.71 hours.
Now we set up a problem here.
50 kilometers/0.71 hours = x kilometers/1 hour
We multiply out 1 hour and cancel out from both sides.
50/0.71 kilometers = 70.42 kilometers.
Therefore, the train was traveling at 70.42 kilometers per hour.

Nate and Maya are building model cars. Maya's car is 3 inches less than 2 times the length of Nate's car. The sum of the lengths of both cars is 26 inches. Write an equation to determine the lengths of Nate's and Maya's cars.
x + 3 − 2x = 26
x + 2x = 26
2x − 3 = 26
x + 2x − 3 = 26
Answer:
x + 2x - 3 = 26
Step-by-step explanation:
Define the variables:
Let x = length of Nate's car.Let y = length of Maya's car.If Maya's car is 3 inches less than 2 times the length of Nate's car, then:
⇒ y = 2x - 3
If the sum of the lengths of both cars is 26 inches, then:
⇒ x + y = 26
Substitute the found expression for y into the equation:
⇒ x + y = 26
⇒ x + (2x - 3) = 26
⇒ x + 2x - 3 = 26
Therefore, the equation to determine the lengths of Nate'a and Maya's cars is:
[tex]\boxed{x + 2x - 3 = 26}[/tex]
Solving the equation for x
⇒ x + 2x - 3 = 26
⇒ 3x - 3 = 26
⇒ 3x - 3 + 3 = 26 + 3
⇒ 3x = 29
⇒ 3x ÷ 3 = 29 ÷ 3
⇒ x = 9.7 in (nearest tenth)
Therefore, Nate's car is 9.7 in (nearest tenth).
To find the length of Maya's car, subtract the length of Nate's car from 26:
⇒ 26 - 9.7 = 16.3 in (nearest tenth).
Therefore, Maya's car is 16.3 in (nearest tenth).
Answer:
d) x + 2x - 3 = 26
Step-by-step explanation:
Given that,
→ Maya's car is 3 inches less than 2 times the length of Nate's car.
→ The sum of the lengths of both cars is 26 inches.
Now the equation will be,
→ x - 3 + 2x = 26
→ x + 2x - 3 = 26
→ 3x = 29
Hence, option (d) is correct answer.
