Answer:
3x^2-1
Step-by-step explanation:
Answer:
f(x) = 3x – 1 and g(x) = x²
Putting the value of g(x) in f(x), we get
(fog)(x)= f{g(x)}= f(x²) = (3x²-1)
(3x²-1) is the right answer.Could anybody help me with this ♀️

What are the coordinates of the point on the directed line segment from (5,5) to
(8,-4) that partitions the segment into a ratio of 1 to 2?
Answer:
[tex](x,y) = (6,2)[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (5,5)[/tex]
[tex](x_2,y_2) = (8,-4)[/tex]
[tex]m:n = 1:2[/tex]
Required
Determine the coordinate of the partition
This is calculated using:
[tex](x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
Substitute values for m,n,x's and y's
[tex](x,y) = (\frac{1 * 8 + 2 * 5}{1+2},\frac{1*-4 + 2*5}{1 + 2})[/tex]
[tex](x,y) = (\frac{18}{3},\frac{6}{3})[/tex]
[tex](x,y) = (6,2)[/tex]

7.987, 8.4082, 8.8, 8.48
Answer:
7.987, 8.4082, 8.48, 8.8
Step-by-step explanation:
there u go
Answer:
7.987, 8.4082, 8.48, 8.8
Step-by-step explanation:
7 is less than 8 (7 < 8) so it would be first. The first place after the decimal, also known as the tenths place decides the numbers that come after. 8.4082 and 8.48 seem similar but are pretty different. When you round 8.4082 it becomes 8.41 which is less than 8.48. That leaves just 8.8 which is your highest number.

A batter hits a baseball 3 ft above the ground toward the center field fence, which is 10 ft high and 400 ft from home plate. The ball leaves the bat with speed at an angle above the horizontal. Is it a home run
Complete Question
A batter hits a baseball 3 ft above the ground toward the center field fence, which is 10 ft high and 400 ft from home plate. The ball leaves the bat with speed at 115 an angle 50 above the horizontal. Is it a home run?
Answer:
[tex]t=5.40sec[/tex]
Step-by-step explanation:
From the question we are told that
Height on hit [tex]H_h=3ft[/tex]
Height of center field fence [tex]H_f=10ft[/tex]
Distance from home plate [tex]D=400ft[/tex]
Initial speed [tex]v_0=115[/tex]
Angle [tex]\theta=50[/tex]
Generally the Parametric equation of the trajectory of a projectile are mathematically represented as
[tex]x=(v_0cos\theta )t[/tex]
[tex]y=(v_0sin\theta )t-\frac{1}{2} gt^2[/tex]
Therefore
[tex]x=(v_0cos\theta )t[/tex]
[tex]x=(115cos50\textdegree )t[/tex]
[tex]x=74t[/tex]
[tex]y=(v_0sin\theta )t-\frac{1}{2} gt^2[/tex]
Initial co_ordinates (0,3)
[tex]y=3+(115sin50\textdegree )t-\frac{1}{2} 32t^2[/tex]
[tex]y=3+88t-16t^2[/tex]
Generally its a home run when Y>10 and x=400
Time when x=400 is
[tex]t=\frac{400}{74}[/tex]
[tex]t=5.40sec[/tex]

if rstu is a rhombus, find m<uts
Answer:
[tex]\angle UTS = 40[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find [tex]\angle UTS[/tex]
From the attachment:
[tex]\angle RSU = 70[/tex]
Because it is a rhombus (all equal sides), then the following relationship exists between the angles
[tex]\angle RSU = \angle SUR = 70[/tex]
Considering triangle RSU.
[tex]\angle RSU + \angle SUR + \angle URS = 180[/tex]
This gives:
[tex]70 + 70 + \angle URS = 180[/tex]
[tex]140 + \angle URS = 180[/tex]
[tex]\angle URS = 180-140[/tex]
[tex]\angle URS = 40[/tex]
[tex]\angle UTS = \angle URS = 40[/tex] --- Opposite angle of a rhombus
Use similar triangles to calculate the height, h cm, of triangle ABE.
Answer:
h=24cm
Step-by-step explanation:
∠DBC=∠ABE (vertically opposite angles)
∠CDB=∠AEB (alternate angles)
∠DCB=∠BAE (alternate angles)
Therefore the triangles DBC and ABE are similar.
That means that the triangles are in ratio to each other.
CD:AE
10:20
1:2
This means that the height of DBC is half the height of BAE.
Since the sum of their heights is 36, h is 2/3 of 36.
The height , h of the traingle is 24 cm.
What are Similar Triangles ?Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
In other words, similar triangles are the same shape, but not necessarily the same size.
In the question , from the figure it is clear that
ΔDBC and ΔABE are similar with AAA Similarity as
∠DBC=∠ABE (vertically opposite angles)
∠CDB=∠AEB (alternate angles)
∠DCB=∠BAE (alternate angles)
According to the theorem if the triangles are similar their sides are in ratio to each other.
CD : AE = 10 : 20 = 1 : 2
This means that the height of DBC = half the height of ABE.
h+h' = 36
h+h/2 = 36
h= 24 cm
Therefore height of ΔABE is 24 cm .
