10 +2 (9−4) x 7
Answer:
80
Step-by-step explanation:
10 +2 (9−4) x 7
PEMDAS
10 + 2(5) x 7
10 + 10 x 7
10 + 70
80
(assuming x in this equation was multiplication and not a variable?)
Hey there!
Just do PEMDAS; PEMDAS simply means…
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
10 + 2 (9 - 4) * 7
= 10 + 2(5) * 7
= 10 + 10 * 7
= 10 + 70
= 80

Solve ax + by = a-b and bx – ay = a+b
Answer: x=1 y=1
Step-by-step explanation:
ax+by=a−b .......... (1)

The first equation in the system models the height, h, of a falling volleyball as a function of time, t. the second equation models the height, h, of the hands of a player jumping up to spike the ball as a function of time, t. which statement describes the situation modeled by this system?
The volleyball is 14 feet above the ground at the instant the player begins her jump.
What is the equation of motion?It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.
We have two equation for two different situations:
[tex]\rm h(t) = 14 - 16t^2\\[/tex] (falling volleyball as a function of time t)
[tex]\rm h(t) = 7+24t-16t^2[/tex] (the hands of a player jumping up to spike the
ball as a function of time t)
First, we have to find the height of the ball above the ground at the instants the player begins to jump:
At t = 0 when the player begins to jump
Put t = 0 in the second equation, we get:
[tex]\rm h(0) = 7+24\times 0-16\times0^2[/tex]
Height of the hand, h = 7 units
Now put t = 0 in the first equation, we get;
[tex]\rm h(0) = 14 - 16\times0^2[/tex]
h = 14 units.
Thus, the volleyball is 14 feet above the ground at the instant the player begins her jump.

4. A line with the preimage equation y = 12x is translated 4 units to the right along the x-axis and 25 units up along the y-axis. Which is the equation of the image line?
Answer:
(d) y' = 12x -23
Step-by-step explanation:
The transformation that translates function y = f(x) by h units right and k units up is ...
y' = f(x -h) +k
__
Your function is ...
y = 12x
and you want to translate it by (h, k) = (4, 25). That makes it ...
y' = 12(x -4) +25 = 12x -48 +25
y' = 12x -23
Which equation represents the circle described? the radius is 2 units. the center is the same as the center of a circle whose equation is x2 y2 – 8x – 6y 24 = 0. (x 4)2 (y 3)2 = 2 (x – 4)2 (y – 3)2 = 2 (x – 4)2 (y – 3)2 = 2² (x 4)2 (y 3)2 = 2²
The equation of the circle x² +y² – 8x – 6y + 21 = 0 is equal to the equation (x + 4)² + (y − 3)² = 2². Then the correct option is C.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² – 8x – 6y + 21 = 0
The equation can be written as
x² – 8x + 16 + y² – 6y + 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

Volume of coneSolution :-
Volume of cone = 1/3πr²hPutting the known values ,
Volume = 1/3×3.14×5²×14 m³
Volume = 366.33 m³
Answer:
366.33 cubic meters[tex] \: [/tex]
Step-by-step explanation:
In the question, it is given that a cone has a radius of 5 meters and a height of 14 meters and we have to find the volume of the cone.
[tex] \: [/tex]
To find the volume of the cone, we must know this formula :
[tex] \\ {\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times \pi \times {(r)}^{2} \times h }}}}}}} \\ \\[/tex]
Where,
r refers to the radius of the cone.h refers to the height of the cone.Now, we will substitute the values in the formula :
[tex] {\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 25 \times 14 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 350 }}}}}}} \\ \\[/tex]

What is the largest perimeter possible for a rectangle with positive whole-number dimensions and an area of 120 square centimeters ?
the largest perimeter possible for a rectangle with positive whole-number dimensions and an area of 120 square centimeters is 242 cm.
What is a rectangle?A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
here, given that,
a rectangle with positive whole-number dimensions and an area of 120 square centimeters.
now, we get,
You could have the width as 1 and the length as 120 making the area 120cm^2 but the perimeter 242.
Hence, the largest perimeter possible for a rectangle with positive whole-number dimensions and an area of 120 square centimeters is 242 cm.

Which statement best describes how to determine whether f(x) = x4 – x3 is an even function? determine whether (–x)4 – (–x)3 is equivalent to x4 – x3. determine whether (–x4) – (–x3) is equivalent to x4 x3. determine whether (–x)4 – (–x)3 is equivalent to –(x4 – x3). determine whether (–x4) – (–x3) is equivalent to –(x4 x3).
Since f(x) ≠ f(- x) then f(x) is not an even function. (–x)^4 – (–x)^3 is equivalent to x^4 – x^3.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
We need to find f(x) = x^4 – x^3 is an even function
If 2 functions are even, then
f(x) = f(- x)
f(x) = [tex]- x^3[/tex]
