Answer:
D) 5.7 cmStep-by-step explanation:
Let the shorter sides be x.
Given:Isosceles and acute triangle.Longer side is 8 cm.To find:The length of the shorter sides, rounded to the nearest tenth.Solution:The angle at common vertex of congruent sides is less than 90°, since it is acute triangle.
It means the other congruent angles are greater than 45°, according to angle sum theorem.
The vertical bisector divides the triangle in half, with base 8/2 = 4 cm and hypotenuse x.
It gives us the inequality:
4/x < cos 45° ⇒ x > 4 / cos 45° = 5.656 x ≥ 5.7 cmCorrect choice is D
When dante was born, his grandparents deposited $10,000 into a special college fund that paid 4% annual interest, compounded monthly. how old was dante when the balance in the account reached$13,000? round your answer to the nearest tenth of a year.
Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, we have that the parameters are given as follows:
A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.
Hence the time in years is found as follows:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]13000 = 10000\left(1 + \frac{0.04}{12}\right)^{12t}[/tex]
[tex](1.0033)^{12t} = 1.3[/tex]
[tex]\log{(1.0033)^{12t}} = \log{1.3}[/tex]
[tex]12t\log{1.0033} = \log{1.3}[/tex]
[tex]t = \frac{\log{1.3}}{12\log{1.0033}}[/tex]
t = 6.6

The given shape in the image is not an equilateral triangle.
What is an equilateral triangle?The triangle with all three sides equal and all the angles equal is called an equilateral triangle.
In the given figure we can see a triangle this triangle is not an equilateral triangle because the figure is formed between a square grid now if you see closely the base of the triangle can not be equal to the two sides of the triangle.
Because these two sides are the hypotenuse for the remaining right-angle triangle. So the base of the highlighted triangle can not be equal to the other two sides of the triangle.

General Sherman, a tree located in Sequoia National Park, stands 275 feet tall. To see the top of the tree,
Carlos looks up at a 19° angle of elevation. If Carlos is 6 feet tall, how far is he from the base of the tree to the
nearest foot?
By using trigonometric relations, we will see that the distance between Carlos and the tree is:
D = 781.23 ft
How far is Carlos for the base of the tree?We can model this with a right triangle. We know that Carlos is 6ft tall, and the height of the tree is 275ft.
Then one of the cathetus of the triangle is equal to:
275ft - 6ft = 269ft.
That cathetus is the opposite cathetus to the angle of 19° (the elevation angle). And the adjacent cathetus is the distance between Carlos and the tree.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
a = 19°opposite cathetus = 269ftadjacent cathetus = D.Replacing that, we get:
tan(19°) = 269ft/D
Solving for D, we get:
D = 269ft/tan(19°) = 781.2ft
So we conclude that Carlos is at 781.23 ft of the tree.
