Answer:
-8
Step-by-step explanation:
f(x)=3x-5
f(-1)=3(-1)-5=-3-5=-8
f(x) = -x^3 + 3x^2 + x - 3 Using the end behavior of f(x), determine the graph of the function
Answer:
Here, the given function,
Since, the leading coefficient is negative, and degree is odd,
Thus, the end behaviour of the function is,
Therefore, the graph rises to the left and falls to the right.
Now, when f(x) = 0
That is, graph intercepts the x-axis at (3, 0), (1, 0) and (-1, 0).
When x = 0,
That is, graph intersects the y-axis at ( 0, -3),
Also, for 0 > x > -1 , f(x) is decreasing,
For 2.55 > x > 0, f(x) is increasing,
For 3 > x > 2.55, f(x) is decreasing,
Find the volume of each figure below. Round to the nearest 10th, if necessary
Answer:
1692.5 ft³
Step-by-step explanation:
Thank you for giving the equation which would help me in solving. We know that our h which is the height is 11 ft. We have to find what the radius. Radius is the have of the diameter. In the figure, the 14 ft is the diameter. So in order to find the radius, we would divide it by 2.
14 ft ÷ 2 = 7 ft
h = 11 ft
r = 7 ft
Now plug it in the equation.
[tex]\pi[/tex]
In the equation you have this sign above. Remember this is the pi sign which is 3.14.
V = 3.14r²h
V = 3.14(7)² × 11
V = 3.14(49) × 11
V = 153.86 × 11
V = 1692.5 ft³
Hope this helps, thank you :) !!
when i multiply it by 6 and subtract 29, the answer is 37.
what is my number?
Let the required number be "x"
According to the statement:
x(6) - 29 = 37
6x - 29 = 37
6x = 37 + 29
6x = 66
x = 66/6
x = 11
Therefore, the required number is 11.
when i multiply it by 6 and subtract 29, the answer is 37.
what is my number?
SOLUTION:▶️Let the required number be x.
According to the question the equation will form like:
▶️6x - 29 = 37
▶️6x = 37+29 (transposing x to RHS)
▶️6x = 66
▶️x = 66/6 (transposing 6 to RHS)
▶️x = 11
VARIFICATION:According to the question :
▶(️11×6) - 29
▶️ 66 - 29
▶️37
Hence varified..

Jennifer needs to use a ladder to clean a second floor window on a building. If the window is 13ft above the ground and the base of the ladder is 4ft from the building, which equation below can be used to determine the length of the
Ladder needed to reach the window
A 42 + 139 = 2
В
4² + x² = 13²
С
132_4? = ?
D
132P = 42
Answer:
Step-by-step explanation:
we have a right triangle,
to find out the hypotenuse, h
H^2=13^2+4^2
H^2=169+8=177
The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
What is Pythagoras theorem?Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building
As per the condition, We have a right triangle.
To find out the hypotenuse x
By Pythagoras theorem,
⇒ x² = 13² + 4²
⇒ x² = 169 + 8
Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.
Hence, the correct answer would be an option (A).

Answer:

If it is a parallelogram, then the sides PS and QR will be parallel, then ∠PSQ and ∠RQS are alternate interior angles, and hence they will be congruent. That is, ∠PSQ ≅ ∠RQS = 25°.
But this is not the confirmation that this would be parallelogram as it could be trapezoid. The given condition is must but not sufficient to prove it.

A group of people went to a coffee shop.
Each person chose a drink and a treat.
number of people who chose coffee: number of people who chose tea = 1:4
Of those who chose coffee,
number of people who chose a muffin number of people who chose a tart = 2:7
Of those who chose tea,
number of people who chose a muffin : number of people who chose a tart = 5:1
What fraction of the people chose a tart?
Answer:
Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]
Step-by-step explanation:
Given - A group of people went to a coffee shop. Each person chose a
drink and a treat. number of people who chose coffee: number of
people who chose tea = 1:4. Of those who chose coffee, number of
people who chose a muffin number of people who chose a tart =
2:7. Of those who chose tea, number of people who chose a muffin
: number of people who chose a tart = 5:1.
To find - What fraction of the people chose a tart?
Proof -
Let the Total number of People went to a coffee shop = 5x
Now,
As given, number of people who chose coffee: number of people who chose tea = 1:4
⇒Total number of people who chooses coffee = [tex]\frac{1}{5}.5x[/tex] = x
Total number of people who chooses tea = [tex]\frac{4}{5}.5x[/tex] = 4x
Now,
As given,
Of those who choose coffee, number of people who chose a muffin number of people who chose a tart = 2:7
⇒Total number of people who choose muffin after coffee = [tex]\frac{2}{9}x[/tex]
Total number of people who choose tart after coffee = [tex]\frac{7}{9}x[/tex]
Also,
Given that
Of those who chose tea, number of people who chose a muffin : number of people who chose a tart = 5:1
⇒Total number of people who choose muffin after tea = [tex]\frac{5}{6}.4x = \frac{20}{6}x[/tex]
Total number of people who choose tart after tea = [tex]\frac{1}{6}.4x = \frac{4}{6}x[/tex]
∴ we get
Total number of people who chooses tart = Total number of people who choose tart after coffee + Total number of people who choose tart after tea
⇒Total number of people who chooses tart = [tex]\frac{7}{9}x[/tex] + [tex]\frac{4}{6}x[/tex]
= [tex]\frac{7}{9}x + \frac{2}{3}x[/tex]
= [tex]\frac{7x + 6x}{9}[/tex]
= [tex]\frac{13}{9}x[/tex]
⇒Total number of people who chooses tart = [tex]\frac{13}{9}x[/tex]
Now,
Fraction of the people chose a tart = [tex]\frac{People choose tart}{Total people}[/tex]
= [tex]\frac{\frac{13}{9}x }{5x}[/tex]
= [tex]\frac{13}{45}[/tex]
⇒Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]

Answer:
x = 13
Step-by-step explanation:
∠ EGB = ∠ AGF = 77° ( vertically opposite angles )
AB is a straight line so the 3 angles on it sum to 180° , that is
90 + x + 77 = 180
x + 167 = 180 ( subtract 167 from both sides )
x = 13

Answer:
D
Step-by-step explanation:
Two lines are parallel if they have the same slope.
the given equation is in the form
y=mx+b
where
m=-5/2
b=-7
m is the slope. You can see this by noting that if you increase x by 1 you increase y by m.
So, in this case, you are looking for a line with slope of -5/2.
You can solve each of the choice equations for y to see which one has the right slope.
A: y=(2/5)x-6 no good
B: y=-(2/5)x-1 no good
C: y=(5/2)x-4 no good
D: y=-(5/2)x-4 GOOD
