Can someone help me, please? I need to find the value of x and y rounded to the nearest tenth. Thank you!

Answer:
[tex]x\approx 24.0,\\y\approx 46.4[/tex]
Step-by-step explanation:
Let the height of the largest triangle marked be [tex]h[/tex]. We can set up the following equation:
[tex]\sin 30^{\circ}=\frac{h}{34},\\h=34 \sin 30^{\circ}=17[/tex] (if you're unfamiliar with trig, this is likely introduced to you as 30-60-90 triangle rules)
This height is also a leg of a 45-45-90 triangle, as marked in the diagram. From the isosceles-base-theorem, the other leg of this triangle must also be equal to [tex]h[/tex]. Therefore, we can use the Pythagorean theorem to solve for [tex]x[/tex]:
[tex]17^2+17^2=x^2\\x^2=\sqrt{17^2\cdot 2},\\x=17\sqrt{2}\approx \boxed{24.0}[/tex] (you can also use trig or 45-45-90 triangle rules which are derived from the Pythagorean theorem)
Segment [tex]y[/tex] consists of two shorter segments, a left segment and a right segment. We've already found that the left segment is equal to 17. To find the right segment we can use trig, the Pythagorean theorem, or 30-60-90 triangle rules (derived from the Pythagorean theorem):
Using Pythagorean Theorem:
[tex]y_{right}=\sqrt{34^2-17^2}\approx \boxed{29.4}[/tex]
Therefore, we have:
[tex]y=17+29.4=\boxed{46.4}[/tex]

The exponent function will be f(x) = 1/3 (4)ˣ. Then the correct option is C.
What is an exponent?Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ
At x = 1, the value of y will be 4/3. Then we have
4/3 = ab ...1
At x = 2, the value of y will be 16/3. Then we have
16/3 = ab² ...2
From equation 1 and 2, we have
b = 4 and a = 1/3
Then the function will be
f(x) = 1/3 × (4)ˣ.
Then the correct option is C.

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

Un joyero tiene forma de un prisma con base hexagonal tiene una altura de 3cm y un volumen de 67.5cm3 cual es el area de su base ??
Answers
Answer:
22.5 cm²
Step-by-step explanation:
La fórmula para el volumen de un prisma con una base hexagonal = Área de la base × Altura
De la pregunta anterior
Área de la base =?
Altura = 3 cm
Volumen = 67.5 cm³
Área de la base = Volumen ÷ Altura
Área de la base = 67.5 cm³ ÷ 3cm
= 22.5 cm²
Por lo tanto, el área si es base = 22.5 cm²
The boys basketall team averages 52 points per game with a standard deviation of 7.0 points. What is the probability that the boys will score between -1.2 and 2.0 standard deviations of their average?
Answers
Answer:
0.6832
Step-by-step explanation:
Given :
Mean, m = 52
Standard deviation, s = 7
-1.2 standard deviation of average = 57 - 1.2(7) = 57 - 8.4 = 48.6
2 standard deviations of average = 57 + 2(7) = 57 + 14 = 71
Zscore = (48.6 - 52) / 7 = - 0.486
Zscore = (71 - 52) / 7 = 2.714
P < -0.486) = 0.31348
P < 2.714 = 0.99668
P < 2.714 - P < -0.486 = (0.99668 - 0.31348) = 0.6832

Find the value of each variable
Answers
Answer:
z = 77
y = 103
Step-by-step explanation:
The angle where 103 and z meet is supplementary, which means it is 180. Since we know one side is 103, we just have to subtract this value from 180 to find the other side, 77.
The total angle measure of a trapezoid is 360. Since we have all the values now except for one, we can simply add them all together: 95 + 77 + 85 = 257. Then, subtract this number, 257, from 360, to get the final angle measure as 103.

(x+1)(x+3)(x+5) = x^3 + 9 x^2 + 23 x + 15
Step-by-step explanation:
If you apply the distributive property, you can expand the expression to x^3 + 9 x^2 + 23 x + 15, from that you can see that:
a = 1
b = 9
c = 23
d = 15
