Answer:
t=2.59s
Explanation:
v=23.5m/s u=15.2m/s a=3.2m/s^2 t=? using equation v=u+at t=(v-u)/a t= (23.5-15.2)/3.2=8.3/3.2=2.59s
Perpendicular lines create obtuse angles where they intersect.
True
False
Answer:
The answer is false
Step-by-step explanation:
Perpendicular lines create four 90 degree angles thus if you connect the edges you make a square that has four 90 degree corners. Lines that can crate obtuse angles are called intersecting angles. And parallel never touch so they don't make any angles

QUESTION:How many paper cups can be filled completely using all of the water from the full water cooler
ANSWER CHOICE:
36
108
144
216
Answer:
108
Step-by-step explanation:
find the volume of the cooler:
V=πr²h
π×6²×16= 1809.56
find the volume of the cup:
V=πr²(h/3)
π×2²×(4/3)= 16.76
divide the volume:
1809.56/16.76= 107.969
Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.

Solve for x: 7 + 4x = 13+ X. Select one: a. x = 1 1/5 b.x=2 x 2 C. X= 4 d. x = 6 2/3
Answer:
7+4x=13+x
4x-x=13-7
3x=6
3 3
x =2
Step-by-step explanation:
because when 7 crosses the equal to sign it becomes negative and when the x from the other side crosses the equal sign it also will become negative which will become 4x-x=13-7
which is 3x=6 so u divide both sides by the coefficient of x which is three which will give u 2

5.2x-y=4.1 1.5x+y=6.7
how to solve this problem
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
Answer:
x = 1.61 (Estimated)
y = 4.28 (Estimated)
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
5.2x − y = 4.1
−y = −5.2x + 4.1
y = 5.2x − 4.1
Solve for x:
1.5x + y = 6.7
1.5x + 5.2x − 4.1 = 6.7
6.7x − 4.1 = 6.7
6.7x = 10.8
x = 1.61194
Solve for y:
y = 5.2x − 4.1
y = 5.2 × 1.61194 − 4.1
y = 4.28209

Solve the equation 6x+3y=3
Answer:
x=−1/2 y+ 1/2
Step-by-step explanation:
Let's solve for x.
6x+3y=3
Step 1: Add -3y to both sides.
6x+3y+−3y=3+−3y
6x=−3y+3
Step 2: Divide both sides by 6.
6x /6= −3y+3/6
x=−1/2 y+ 1/2

Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that
[tex]f(x)=(x-8)(something)[/tex]
[tex]\frac{f(x)}{x-8}=something[/tex]
so we divide and get that
[tex]something = x^{2} -6x+9x[/tex]
and we can factor it as
[tex](x-3)(x-3)[/tex]
so the other solutions are
x-3 =0
x = 3
this is a normal division
Answer (#17):
(x-3) (x-3) or (x-3)²
Step-by-step explanation:
See attachment to find simplified equation. I can't explain synthetic division very well. Please find other sources to learn synthetic division or traditional algebraic long division.
Anyway, the image should be read first while this text explains the second part. Now you have the second equation, it can be factored down.
[tex]x^2-6x+9 = (x-3)(x-3)[/tex]
The function in factored form is : (x-3) (x-3)

The function f(x) = -x² + 8x-7 is translated five units down. Write the new equation in vertex form and state the vertex.
Answer:
The resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
Step-by-step explanation:
The given function is f(x) = -x² + 8x-7.
As the given function is translated 5 units down, so, subtract 5 units in the given function.
The resulting function, y = f(x) -5
[tex]\Rightarrow y= - x² + 8x - 7 - 5 \\\\\Rightarrow y = - x² + 8x - 12[/tex]
Now converting the obtained equation to vertex form,
[tex]y= - x² + 8x - 12 \\\\\Rightarrow y = -(x^2-8x+12) \\\\[/tex]
Adding and subtraction 4 as
[tex]y= -(x^2-8x+12+4-4) \\\\\Rightarrow y= -(x^2-8x+16-4) \\\\\Rightarrow y= -((x-4)^2-4) \\\\\Rightarrow (y-4)=-(x-4)^2[/tex]
The vertex of the above equation is (4,4).
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is [tex](y-4)=-(x-4)^2[/tex] having the vertex at the point (4,4).
On translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).
The given function is f(x)= -x²+8x-7.
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
When the shape is moved down by k units, then replace y with y - k.
The function f(x) = -x² + 8x-7 is translated five units down.
That is, y=f(x)-5
y=-x² + 8x-7-5
y=-x² + 8x-12
Subtract 4 on both the sides of an equation, we get
(y-4)=-x² + 8x-12-4
(y-4)=-x² + 8x-16
(y-4)=-(x²-8x+16)
(y-4)=-(x-4)²
Hence, on translating five units in the downwards direction, the resulting equation in the vertex form is (y-4)=-(x-4)² having the vertex at the point (4,4).
