Answer:
Step-by-step explanation:
To find the highest point we use t = -b/2a (because that's the equation used to find the maximum of the function which is the maximum height the rocket reaches before heading back down ( aka highest point of the parabola at the turning point)
f(t) = -4.9t^2 +15 +10
A = -4.9
B = 15
C=10
Plug it in
-15/2(-4.9) = 1.53 seconds
(In case you get confused 15 turns negative because b in the equation has a - symbol in front. If you had -15 as B you would put -(-15) making it positive)
Hope this is helpful
1.53seconds after launch, will the rocket reach its highest point.
What is height?In mathematics, height is defined as the vertical distance from the top of an object to the bottom. Sometimes it is labeled as "height".
The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.
Height is a way of measuring someone or something from the bottom to the top or from the head to the feet. In other words, height indicates how tall someone or something is. We can compare how tall we will be when we grow up. We often compare the average height of men and women in different countries.
Given:
f(t)=−4.9t2+15t+10
The vertex is the highest point of the function
when t= [tex]\frac{-b}{2a}[/tex]
=[tex]\frac{-15}{2(-4.9)}[/tex]
≈ 1.53
f(t) is the maximum value
1.53seconds after launch, will the rocket reach its highest point.

SA = 2tr2 + 2trh (Use 3.14 for .) How much metal is needed to create a cylindrical can with a height of 5 inches and a base diameter of 3 inches? square inches Do NOT round your answer.
Answer:
[tex]SA=61.26\ \text{inches}^2[/tex]
Step-by-step explanation:
The surface area of a cylinder is given by :
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where
r is radius and h is height of the cylinder
We have, h = 5 inches and r = 3/2 = 1.5 inches

Answer:
384 cm²
Step-by-step explanation:
The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.
To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:
For parallelogram:
Height (H) = 7.5 cm
Base (B) = 24 cm
Area of parallelogram (A₁) =?
A₁ = B × H
A₁ = 24 × 7.5
A₁ = 180 cm²
For rectangle:
Length (L) = 24 cm
Width (W) = 8.5 cm
Area of rectangle (A₂) =?
A₂ = L × W
A₂ = 24 × 8.5
A₂ = 204 cm²
Finally, we shall determine the area of the shape.
Area of parallelogram (A₁) = 180 cm²
Area of rectangle (A₂) = 204 cm²
Area of figure (A)
A = A₁ + A₂
A = 180 + 204
A = 384 cm²
Therefore, the area of the figure is 384 cm²

What does X and Y equal?
Answer:
X= 67
Y= 6
Step-by-step explanation:
Triangle TRU is an equilateral triangle which means all sides are equal.
Triangles sum up to 180°.
180/3= 60
60+7= 67
x=67
Triangle TRS is an isosceles triangle which means it has two equal sides.
Triangles sum up to 180°.
180-60= 120
TRS= 120°
60/2= 30°
RTS= 30°
RST= 30°
30/5= 6
y= 6
What do all rhombuses have in common
Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides.
All rhombuses have equal sides and diagonals that bisect each other at right angles.
We have,
All rhombuses have the following characteristics in common:
- Equal Sides:
A rhombus is a quadrilateral with all four sides of equal length.
Each side of a rhombus has the same measurement.
- Opposite Angles are Equal:
The opposite angles of a rhombus are congruent (equal in measure). This means that if we label the angles A, B, C, and D in a clockwise or counterclockwise direction, then angle A is congruent to angle C, and angle B is congruent to angle D.
- Diagonals Bisect Each Other:
The diagonals of a rhombus are perpendicular bisectors of each other. This means that the diagonals intersect at a right angle, and they divide each other into two equal halves.
- Diagonals are Equal in Length:
The two diagonals of a rhombus are of equal length. If we label the endpoints of the diagonals as E, F, G, and H, then EF = GH.
Thus,
All rhombuses have equal sides and diagonals that bisect each other at right angles.

Answer:
The 20-count batteries have a lower unit price of $0.76 per battery
Step-by-step explanation:
Unit price means how much does it cost if you buy one of the item. To calculate this take the amount of money it cost and divide by the amount of object you have.
In the case of this question we know that you can buy 8 batteries for $6.16 and 20 batteries for $15.20. Let's find the unit cost (how much for one battery) for each of these packs. To calculate that we can take $6.16/8 batteries = $0.77 per battery for the 8 pack and $15.20/20 = $0.76 per battery for the 20 pack. Therefore, the 20-count batteries have a lower unit price of $0.76 per battery.
