In a right triangle, the base is 12 m and the hypotenuse is 15 m. What is the length of height?
A. 81m
B. 9 m
C. 12 m
D. 19.2 m
HELP NOW PLEASE
Answer:
L = Hyp²-B²
L=15²-12²
L =225 - 144 = 81
L= √81=9
L= 9mthe measure of a base isosceles triangle is 43? what is the measure of the vertex angle
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees

The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.
Answer:
speed of the rocket is 6feet
Step-by-step explanation:
Complete question
The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
Note that the average rate is also known as the speed
Average rate = h(3)-h(1)/3 - 1
h(3) = 3+70(3) - 16(3)^2
h(3) = 3 + 210 - 144
h(3) = 69
h(1) = 3+70(1) - 16(11)^2
h(1) = 3 + 70 - 16
h(1) = 73 -16
h(1) = 57
Average rate = 69-57/3-1
Average rate = 12/2
Average rate = 6ft/s
This shows that the speed of the rocket is 6feet
Answer:
If you're looking for the answer for edge, its;
B. The rocket is at a greater height when t = 3 than when t = 1.

answer: x = -7/4
12 = -4x +5
Subtract 5 from both sides.
7 = -4x
Divide both sides by -4.
-7/4 = x
Flip if you want.
x = -7/4

The given point (-3, -9) is reflected over X-axis
Answer:
The correct answer is (3, 9)
Step-by-step explanation:
The rule for reflecting over the X-axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X-axis and mapped onto point P', the coordinates of P' are (5,-4).

Pythagorean theorem level 2 delta math
The third side is [tex]\sqrt{42}[/tex]
So Pythagorean's theorem is the following
[tex]Short^2 + Long^2 = Hypotenuse^2[/tex]
From here we can input the following information that we know
[tex]Short^2 + 4\sqrt{3}^2 = 8^2\\Short^2 + 12 = 64\\Short^2 = 64 - 12\\Short^2 = 42\\Short = \sqrt{42}\\[/tex]
Jacqueline had $.84 her brother gave her another $.61 write the amount of money Jacqueline now has as a decimal explain
Answer:
$1.45
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Money already had = $.84
Brother gave = $.61
So, total money Jacqueline has = Money already had + Brother gave money
= $.84 + $.61
= $1.45
Explanation : Total money Jacqueline has will be the total of the sum of the money she already had and the money her brother gave him.

A cylinder with a radius of 4 cm and a height of 9 cm has the same volume as a cone with a radius of 3 cm. What is the height of the cone?
Answer:
D. 48 cm
Step-by-step explanation:
Cylinder Volume:
V=πr^2h
V≈452.39
Cone Volume:
V=πr^2(h/3)
452.39 = pi(3)^2(h/3)
452.39 = pi x 9 x (h/3)
452.39 = 28.26 x (h/3)
/28.26 /28.26
16.008138712 = (h/3)
x 3 x 3
h = 48.0244161359
h = 48 cm
A car that is purchased got 24000 is expected to depreciate at a rate of 7% per year. If the function f(x)=ab^x models this situation, which function could be used to find the value of the car after 10 years?
Answer:
FV= 24,000*(1.07^-10)
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $24,000
Decrease rate (d)= 7%
Number of periods (n)= 10 years
To calculate the value of the car after 10 years, we need to use the following formula:
FV= PV*(1+d)^-n
FV= 24,000*(1.07^-10)
FV= $12,200.38
A cell phone company data about students texting skills.They collected the texting speed in words per minutes according to time in minutes.Identify the data's independent and dependent values
Answer:
independent variable = Time
Dependent variable = texting speed
Step-by-step explanation:
The Independent and dependent variables are used in regression analysis for making prediction. The Independent variable also called the predictor are the variables or data collected in other to influence or determine the outpjt obtained which is the dependent or predicted variable. Hence, the aim or prediction we wish to obtain, measure or determine is the dependent variable In the scenario above, the aim of the data collected is to determine the typing skill, here, the dependent variable is the typing skill. The data required to define the bthis is the data collected on typing speed which measures time taken to type.
Therefore, independent variable = Time
Dependent variable = texting speed
