The flip should tur after 2.4 scon
How to find the point of intersection of two linesGiven the following functions expressed as:
[tex]Y = - (x - 5)^2 + 3 \\y = -3(x - 6)^2 + x + 1[/tex]
Equating both expression will give
-(x-5)² + 3 = -3(x-6)² + x + 1
-(x-5)² +3(x-6)² + 3 - x - 1 = 0
-(x-5)² +3(x-6)² + 2 - x = 0
-(x² - 10x + 25) + 3(x²-12x + 36) + 2 - x = 0
x² + 10x - 25 + 3x² +36x + 108 + 2 - x = 0
4x² + 45x + 85 = 0
Factorize for the value of x
On factorizing, the value of x is 2.405
Hence the flip should tur after 2.4 sconds

How many triangles can be constructed with side lengths of 1.8 cm, 3.4 cm, and 5.6 cm?
0
1
more than one
Answer: One triangle
Step-by-step explanation:
-The triangle's dimensions are defined and fixed.
-Given the fixed dimensions, only one unique triangle can be constructed.
-Hence, only one triangle of the dimensions 7.2cm, 6.9cm and 12.8 cm can be formed.
Answer:
1
Step-by-step explanation:
The correct shape would be a scalene triangle, which can't be bent and twisted and still have the same side lengths.
Does the relation in the table represent direct variation, inverse variation, or neither? If it is direct or inverse variation, write an equation to represent the relation. Explain your answer.
Answer:
Indirect variation
Step-by-step explanation:
If two variables change in inverse proportion, then it is called indirect variation.
xy = k where k is a constant.
5*2 = 10
10*1 =10
[tex]15*\dfrac{2}{3}=5*2=10\\\\\\20*\dfrac{1}{2}=10[/tex]
So, this is indirect variation.

Suppose you decide to run at least 7.5 miles per week during the week to train for the cross-country season in the fall. During one week, you run 2 miles on Sunday and 2.5 miles on Wednesday. How many more miles, m, do you need to run before the week is over? *
Given :
You decide to run at least 7.5 miles per week during the week to train for the cross-country season in the fall.
During one week, you run 2 miles on Sunday and 2.5 miles on Wednesday.
To Find :
How many more miles, m, do you need to run before the week is over.
Solution :
Total number of miles we travelled till Wednesday :
t = miles run on Sunday + miles run on Wednesday
t = 2 + 2.5 miles = 4.5 miles.
Now, number of miles remaining :
R = Total target - t
R = 7.5 - 4.5 miles
R = 3 miles.
Therefore, we need to run 3 more miles before the week is over.
Hence, this is the required solution.

A truck whose bed is 8.5 feet long, 5 feet wide, and 3.5 feet high is delivering sand for a sand sculpture competition. How many trips must the truck make to deliver 400 cubic feet of sand?
Answer:
The truck will need to make 3 trips.
Step-by-step explanation:
First, we need to find the volume that the truck can carry. Using the dimensions of the truck and the volume formula, we have:
[tex]V=lwh\\V=8.5\times5\times3.5\\V=148.75\text{ ft}^3[/tex]
Since we need to move a total of 400 cubic feet, we will divide that amount by the truckload capacity (volume).
[tex]400 \div 148.75 \approx 2.689[/tex]
In context, he will need to take three truck loads: two loads will be full, and the third will not be full.

At what x-values are the equations equal?
x = 1 and x = 3
x = 0 and x = 1
x = 1 and x = -1
x = 2 and x = 3
Answer:
x = 1 and x = 3
Step-by-step explanation:
Let's solve your system by substitution.
y=2x+1;y=3x
Step: Solvey=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=3x:
y=3x
2x+1=3x
2x+1+−3x=3x+−3x(Add -3x to both sides)
−x+1=0
−x+1+−1=0+−1(Add -1 to both sides)
−x=−1
−x
−1
=

(Divide both sides by -1)

HELP PLS find measure of w in this trapezoid
Answer:
m<w= 36°
Step-by-step explanation:
Step 1) Applying geometric and algebraic knowledge, the two angles to the left are both 90, and equal to 180. If you add those two angles and the 146°, you will be given 326 in total.
90+90= 180 +146 = 326
Step 2) With knowledge that the sum of all interior angles inside of a quadrilateral add up to 360, subtract 326 from this.
360-326=36
Final product: m<w=36°

Individuals of the same approximate weight running 6 mph or 1 mile every ten minutes have a calorie use factor of 62% of their weight; i.E., calories burned = (weight)(0.62). If they run an 8-minute mile, the factor is 65%. A man weighs 180 lb. He jogs a mile in 8 minutes. How many calories has he used up?
Answer: He has used up 117 calories.
Step-by-step explanation:
Given, For 62% as factor, calories burned (E)= (weight)(0.62).
Also, if they run an 8-minute mile, the factor is 65%. [given]
Then, calories burned (E)= (weight)(0.65). [65%=0.65]
Weight of man = 180 lb
Then, calories burned (E)= 180 x (0.65).
= 117
Thus , he burned 117 calories.
So, he has used up 117 calories.

Answer:

Step-by-step explanation:
1/5th the original price just means 20%
20% of 700 is 140
700*.20= 140
Since it's 20% off that means subtraction

What is the quotient. Of 25)9250
Answer:
370
Step-by-step explanation:
Isolate the numbers so that you are only dividing sections at a time.
So 25 goes in to 92 three times. so we multiply 25 by three and subtract that from 92. Put the three at the top and repeat throughout.
92-75=17
Bring the next number down and repeat.

Answer: 32ft²
Step-by-step explanation:
The area of a trapezoid is given by the formula: A = [(b1+b2)/2] x h, where b1 and b2 are the two bases, and h is the height.
In our situation, b1 = 3, and b2 = 5. The height is given as 2.
Plugging these numbers into our formula:
A = (b1+b2)/2 x h
A = [(3+5)/2] x 2
A = (8/2) x 2
A = 4 x 2
A = 8ft²
8ft² is the area of one trapezoid. If Mr. Smith wants to fit 4 of these shapes into the room, the combined area will be 4 x 8 = 32ft².

HELPP 5 POINTS Here's a graph of a linear function. Write the equation that describes that function.
Express it in slope-intercept form.
Step-by-step explanation:
m = (y2-y1)/(x2-x1)
m = (4-0)/(0-(-8))
m = 4/8
y = mx + c
4 = (4/8)(0) + c
c = 4
Thus, the equation is y = (4/8)x + 4

What equation is equivalent to 5(2p - 6)= 40
4/7 divided by 2 1/3 = ???
Answer:
[tex]\frac{12}{49}[/tex]
explanation:
Use the keep change flip method. This consists of literally flipping a fraction to make the denominators alike, allowing for faster solves and multiplication.
[tex]2\frac{1}{3}[/tex] is [tex]\frac{7}{3}[/tex], so flip 7/3 so it is 3/7, matching up with 4/7.
Next, multiply.
4 x 3
7 x 7
4 x 3 is 12. Write 12 as a numerator.
7 x 7 is 49. Write 49 as a denominator.
Therefore, the answer is [tex]\frac{12}{49}[/tex]

The measure of angle Q is 70 degrees. Find the measure of angle P.
Answer:40
Step-by-step explanation: because 70 times 2 = 140 and you add 40 will equal 180 because every triangle equals 180
The measure of angle m<P is 40 degrees
The given triangle is an isosceles triangle where:
m<R = m<Q
Taking the sum of the interior angles, we will have:
m<P + ,m<Q + m<R = 180
70 + 70 + m<P = 180
m<P = 180 - 140
m<P= 40 degrees
Hence the measure of angle m<P is 40 degrees
