A circus juggler on the highwire gives a bowling pin a final toss into the air with an initial velocity of 9 meters per second from a height of 11 meters. The time taken by the object to hit the ground is 2.7 seconds.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
It is given that,
Initial velocity of an object, u = 9 m/s
Height, h = 11 m
The equation that models the height of the object in meters after t seconds is :
[tex]h(t)= -4.9t^2+9t+11[/tex]
We have to find the time it take for the bowling pin to hit the ground
i.e. [tex]-4.9t^2+9t+11=0[/tex]
On solving the above quadratic equation, we get the value of time t is :
t = 2.7 seconds
Hence, The time it takes to hit the ground would be 2.7 seconds.

Step-by-step explanation:
The side opposite angle A is 35 and that adjacent to angle A is 12. The trig function that connects A and these two sides is
tan A = (opp) / (adj)
which here is
tan A = 35/12. Find A using a calculator's arctan function:

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.
What is the length of the rectangle?
0.75 units
1.5 units
3 units
6 units
Answer:
6 units
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
A rectangle’s width is one-fourth of its length.
W = 1/4 × L
W = L/4
Cross Multiply
L = 4W
A = 9 square units
Hence
9 = L × W
We substitute 4W for L
9 = 4W × W
9 = 4W²
We square root both side
√9 = √4W²
3 = 2W
W = 3/2
W = 1 1/2 unit or 1.5 units
Solving for L = Length
9 = L × W
9 = L × 1.5
L = 9/1.5
L = 6 units
Therefore, the Length of the rectangle = 6 units

Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

Answer:
36
Step-by-step explanation:
for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this
1^3 + 2^3 + 3^3
or expanded out
(1x1x1)+(2x2x2)+(3x3x3)
Solving that down, the equation turns into this
1 + 8 + 27
Adding those values together leaves us with 36!
Hope this helped, have a good rest of your day!
Answer:
36
Step-by-step explanation:
[tex]1^{3}[/tex] + [tex]2^{3}[/tex] +[tex]3^{3}[/tex] = 36
[tex]1^{3}[/tex] = 1 x 1 (= 1) x 1 = 1
[tex]2^{3}[/tex] = 2 x 2 (= 4) x 2 = 8
[tex]3^{3}[/tex] = 3 x 3 (= 9) x 3 = 27
27 + 8 + 1 = 36

Which pair of triangles can be proven congruent by SAS?
Third pair of triangles is congruent by SAS.
What is congruency?In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.
In the third pair, this rule is visible. Two pair of sides are equal to each other and the angles formed at the common vertex of the two sides are equal. Hence, the two triangles are congruent by SAS.
