Answer:
Yes
Step-by-step explanation:
A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.
If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:
[tex]2.7^2+1.9^2=10.9[/tex] cm
While squaring our hypotenuse gives us
[tex]3.3^2=10.89[/tex] cm
The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.
In a lab, 450 cells are present at the beginning of an experiment. The number of cells increased by 18% each hour. a) Write an exponential growth model giving the number of cells y present t hours after starting the experiment. b) Estimate the time when the number of cells is 1,030.
Answer:
Step-by-step explanation:
y = 450 × 1.18^t
:::::
450 × 1.18^t = 1,030
1.18^t = 1,030/450 = 103/45
t×ln(1.18) = ln(103/45)
t ≈ 5 hours

Step-by-step explanation:
Hello There!
Once again we are going to use trigonometry to solve for x
Here are the Trigonometric Ratios
sin = opposite divided by hypotenuse
cos = adjacent divided by hypotenuse
tan = opposite divided by adjacent
we need to find x and we are given its opposite side length (58) and the adjacent side length (19)
this corresponds with tangent so once again we will be using tangent to solve for x
Looking at tangent we see that its equal to opposite divided by adjacent so we create an equation
[tex]tan(x)=\frac{58}{19}\\\frac{58}{19} =3.052631579[/tex]
now we have
[tex]tan(x)=3.052631579[/tex]
Once again we need to get rid of the tan
to do so we take the inverse of tan ( tan^-1) and apply it to each side
[tex]arcsin^-^1(tan(x))=x\\arcsin^-^1(3.052631579)=71.86191784[/tex]
finally we round to the nearest tenth
we're left with x = 71.9

unless there is a value for x then that is all i can do
hope this helps:)
Answer: 10x - 8
Step-by-step explanation:
(7x - 3) -(5-3x)
= (7x - 3) - 5 + 3x Made them without parentheses. For -(5-3x), because there are - in front them, which means to multiply -1, so it become -5+3x.
= 7x - 3 - 5 + 3x
= 7x + 3x - 3 - 5
= 10x - 8

One serving of a certain brand of yogurt contains 8 g of fat the local fat version control is 45.25% less fat per serving how many grams of fat does one serving the low fat yogurt. The low fat yogurt contains how many g of fat.
Answer:
3.62 grams
Step-by-step explanation:
Multiply by .4525 to get the answer.
(For percentages you want to move the decimal to the very front. Ex. 2% = 0.02 and multiply by the number you have, in this case 8 grams.)
This should look like this: 0.4525*8=3.62
What equation represents this function?
Duncan is running to raise awareness and money for cancer. He finds 2 people who have pledged to
donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet
Duncan runs. His aunt also says that she will donate $12 for every mile he runs. If Duncan runs a total of
7 miles during the cancer awareness run, how much money will he have raised based on these two
donations?
Answer:
$1008
Step-by-step explanation:
12 x 7 = $84 his aunt gives him.
1 mile = 5,280 feet
5,280 x 7 = 36,960 feet he ran.
5,280 ÷ 40 = 132 for every mile he runs
132 x 7 = $924 from his neighbor.
924 + 84 = 1,008

Answer:
D. h(x) = 5x² +12x +9
Step-by-step explanation:
The final constants are mostly different, so you can simplify your work by just figuring that one.
h(x) = g(x) -f(x)
h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D
__
If you want to figure the whole expression ...
h(x) = g(x) -f(x)
h(x) = 12x² +7x -7 -(7x² -5x -16)
h(x) = 12x² +7x -7 -7x² +5x +16
h(x) = (12 -7)x² +(7 +5)x +(-7 +16)
h(x) = 5x² +12x +9 . . . . . matches choice D

Triangle DFE with coordinates D(0,0), F(3,0), and, E(3,1) is similar to triangle EHG. If vertex G has coordinates (9,3), what are the coordinates of vertex H?
Answer:
coordinates are (x,y)->(x+6,y+2)
F's coordinate is (3,0)
using the coordinates we get (9,2)
Therefore the coordinates are (9,2)
The required coordinates of vertex H are (6,2).
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
Given that triangles DFE and EHG are similar.
This means that the ratios of the lengths of their corresponding sides are equal.
As per the question, we have:
DF/FH = DE/EG
Since DF = 3 and DE = 1, we can set up the following equation to find the length of FH:
FH = EG × (DF/DE)
Substituting the known values, we get:
FH = EG × (3/1)
As we know that EG = 6, we can substitute this value to find that FH = 18.
The coordinates of F are (3,0) and the coordinates of H are (x,y), we can set up the following equations to find the values of x and y:
x - 3 = 18
y - 0 = 2
Solving these equations, we find that x = 21 and y = 2.
Thus, the coordinates of vertex H are (6,2).
