Answer:
5.25 seconds
Step-by-step explanation:
When the ball hits the ground the height is zero
Equate f(t) to zero and solve for t , that is
- 16t² + 84t = 0 ← factor out - 4t from each term
- 4t(4t - 21) = 0
Equate each factor to zero and solve for t
- 4t = 0 ⇒ t = 0
4t - 21 = 0 ⇒ 4t = 21 ⇒ t = [tex]\frac{21}{4}[/tex] = 5.25
t = 0 is the time when the ball is kicked
t = 5.25 is the time taken for the ball to hit the ground

Answer:
B
Step-by-step explanation:
Let's eliminate the incorrect answers. C and D are incorrect, since anything to the power of 0 is equal to 1. A is incorrect, because -1 * -1 = 1 since the negatives cancel out. B is correct, because -1*-1*-1*-1*-1 has an odd number of negatives, and thus you are left with -1 instead of 1. Therefore, the answer is B.

Plz HELP Directions: Write your own recipe for trail mix with a catchy name that will make
people want to eat it. You can also create a slogan, logo, or package design for the
mix. Your recipe must meet the following contest guidelines:
1. It must have at least five different ingredients.
2. The amount of each ingredient should be represented by a different mixed
number.
3. The recipe must make exactly 10 cups of trail mix.
After you write your recipe, complete the following for your contest entry:
• Prove that your recipe makes exactly 10 cups.
• Explain the most efficient method for measuring each ingredient using only
the following two measuring cups:
1
3
cup and
1
4
cup. You can use one or
both of the measuring cups. Note: Depending on the fractions that you chose
for your ingredient amounts, it may not be possible to create each exact
amount using only
1
3
and
1
4
measuring cups. If you need to, you can round
your ingredient amounts using benchmarks and then explain how you would
estimate that amount. For example, if you need
4
7
cup of an ingredient,
4
7
cup is slightly more than
1
2
cup. You could fill up your
1
4
measuring cup twice
to make
1
2
cup of that ingredient, and then add just a tiny bit more to
estimate
4
7
cup.
• Use equations or other models to show how you would measure each
ingredient amount with only the two measuring cup sizes.
Your recipe and explanations will be submitted as your portfolio assessment.

Arianna needs 3/4 cup of flour to bake a batch of cupcakes. she has 1/2 cup of flour. what fraction of a batch can Arianna bake?
Answer:
She can bake 3/8 of a batch of cupcakes.
Step-by-step explanation:
If she only has 1/2 of the flour and you are trying to find the fraction of a batch she can make, you are essentially trying to figure out what is 1/2 of 3/4, which is basically just multiplying 1/2 by 3/4. This would get you the answer of 3/8. Hope this helps:)

Answer: x = 90°, therefore 3x = 270°
Step-by-step explanation:
The null space on the left of the shape is a 45-45-90 triangle. Since the internal angle is therefore 90°, 3x = 360°-9°, solving for x this yields x= 90°.
Natalia is writing a recursive formula to represent the sequence.
8, 12, 18, 27, ...
What value should she use as the common ratio in the formula?
Answer:
There is no common ratio.
Step-by-step explanation:
I divided each number in the sequence from the number preceding it and the answer was not one of the numbers in the series. this would mean that there is no common ratio. (please correct me if i am wrong)

-5 ( x - 1 ) - x + 1 = -18
Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
Answer:
x=-4
Step-by-step explanation:
-5 ( x - 1 ) - x + 1 = -18
-5x+5-x+1=-18
6x+6=-18 <- -6 from both sides
6x=-24 <- divide 6 by both sides
x=-4

For each parallelogram below, find the values of the missing sides or
angles.
Answer:
m ∠DCA
m ∠CAD = 56
m ∠CBA = 83°
Step-by-step explanation:
A parallelogram is a polygon with two pairs of parallel lines
m ∠CDA = m ∠CBA = 83° Opposite angles in a parallelogram are =
m ∠CAD = m ∠ACB = 56° CB ║ DA and alternating interior angle are =
m ∠DCA = 180° The sum of the angles in a triangle = 180°
m ∠ADC + m ∠CAD + m ∠DCA = 180 Parts of the triangle
83° + 56° + m ∠DCA = 180 Substitution
139° + m ∠DCA = 180°
m ∠DCA = 180° - 139°
m ∠DCA = 41°

i need help i dont really understand what they mean by y=-x+7 please help me ty and no links!!
Answer:
Step-by-step explanation:
y = -x + 7 is a linear equation in slope-intercept form, y = mx + b.
The slope (m) measures the unit changes in the output (y ) for each one-unit change in the input (x) value.
b = the y-ccordinate of the y-intercept, (0, b). The y-coordinate, b, is what you will use for the slope-intercept form. The y-intercept is the point on the line where it crosses the y-axis.
Graphing y = - x + 7:To graph y = -x + 7, use the slope, m = -1 (down 1 unit, run 1 unit), and the y-intercept, (0,7) to plot points on the graph to connect a line with.
Vertical Line (Definition):The equation, x = 3 represents a vertical line with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate. Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as using the slope formula, m = (y₂ - y₁)/(x₂ - x₁), as it will involve a division by zero (which consitutes an undefined operation).
Graphing x = 3:To graph x = 3, choose any point on the graph that has an x-coordinate of 3, then draw a vertical line from there.
The given equation has a solution that occurs at point (3, 4). Attached is an edited screenshot of the image that you uploaded.

Rotate this figure 270 degrees clockwise
Answer:
it's the third answer
Step-by-step explanation:
360 degrees is a full circle so you subtract the 90 degrees from it and get 270. The only turn it would need to be a full 360 is 90 degrees. hope this helps
Answer:
its the one pointing to the right
Step-by-step explanation:
if its pointing down then goes 180 clockwise, then it will be pointing straight up, then 270-180 is 90 so it goes 90 degrees clockwise.

Step-by-step explanation:
A square mirror has a frame of length 64cm, then the length of each side is_________.
Answer:
the length of each side will be 16 cm.
Step-by-step explanation:
you can find the answer by dividing 64 by 4. the four is the sides of the square.
Answer: 16cm
Explanation:
If the mirror is a square and squares' sides are all the same length and they have four sides, you just divide 64 by 4 and get the answer of 16.
The island of Martinique has received $32000 for hurricane relief efforts. The island’s goal is to fundraise more than y dollars for aide by the end of the month. They receive donations of $4500 each day. Write an inequality that represents this situation, where x is the number of days.
Answer:
y=4500x+32000
Step-by-step explanation:
If they are increasing at a constant rate of 4500 then that is the coefficient of x, and if they received a 32000$ donation then that is the y-intercept so you add that to 4500x to get this equation.

d= 4/5a + h solve for a
Answer:
5/4d - 5/4h = a or a = 5d-5h/4
Step-by-step explanation:
d = 4/5a + h
~Subtract h to both sides
d - h = 4/5a
~Multiply 5/4 to both sides
5/4d - 5/4h = a or a = 5d-5h/4

Determine whether or not the relation is a function. Please help asap
Answer:
A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function
