How do you solve this???[tex]\frac{3}{2}r = -1[/tex]
Answer:
[tex]\boxed{\sf{r=-\dfrac{2}{3} }}[/tex]Step-by-step explanation:
Isolate the term of r, from one side of the equation.
3/2r=-1First, multiply by 2 from both sides.
2*3/2r=2(-1)
Solve.
3r=-2
Then, you divide by 3 from both sides.
3r/3=-2/3
Solve.
Divide the numbers from left to right.
r=-2/3
-2/3=-0.66
[tex]\Longrightarrow: \boxed{\sf{r=-\dfrac{2}{3}}}[/tex]
Therefore, the correct answer is r=-2/3.I hope this helps! Let me know if you have any questions.

The difference of two numbers is 9 if the larger number is one more than twice the smaller number find the larger number
Answer:
17
Step-by-step explanation:
let the two numbers be X and Y
let larger number = Y
from the first statement
Y - X = 9 equation (1)
from the second statement
Y = 1+ 2X equation (2)
substitute equation (2) into (1)
1+2X-X = 9
1+X= 9
X = 9-1 = 8
X= 8
put X = 8 into equation (2)
Y= 1+2X
Y= 1+2(8)
Y= 1+16 = 17
larger number = 17.

Can someone help me find the value of y and how to my got it
Explanation:
The tickmarks tell us that sides HG and FG are the same length. The triangle is isosceles. Directly from this, we know that the opposite angles F and H are congruent. Both are 4y-7 degrees.
Angle G is 90 degrees because of Thales' Theorem. This is because HF is the diameter of the circle. It's also the hypotenuse of the right triangle.
For any triangle, the three interior angles always add to 180 degrees.
F+G+H = 180
(4y-7) + (90) + (4y-7) = 180
8y + 76 = 180
8y = 180-76
8y = 104
y = 104/8
y = 13
Directions: Simplify and write in standard form, letting f(x) = x2 + 2x + 1, g(x) = 3 - 2x,
h(x) = 2x2, and k(x) = x +4.

Graph this parabola
Show all steps please!!!
In this case, the equation is in vertex form. To graph the parabola, we need to determine the y-intercept, x-intercept(s), and the vertex.
Vertex of Parabola:Vertex form: y = a(x + h)² - k
⇒ [y = 3(x + 2)² - 1] and [y = a(x - h)² - k] ⇒ Vertex: (h, k) ⇒ (-2, -1)X-intercept(s) of Parabola:Assume "y" as 0.
[tex]\implies 0 = 3(x + 2)^{2} - 1[/tex]
[tex]\implies 1 = 3(x + 2)^{2}[/tex]
Take square root both sides and simplify:
[tex]\implies\sqrt{1} = \sqrt{3(x + 2)^{2}}[/tex]
[tex]\implies1 = \sqrt{3 \times (x + 2) \times (x + 2)}[/tex]
[tex]\implies1 = (x + 2) \times \sqrt{3[/tex]
Divide √3 both sides:
[tex]\implies \±\huge\text{(}\dfrac{1 }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]
[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]
Multiply √3 to the numerator and the denominator:
[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} \times \sqrt{3} }{\sqrt{3\times \sqrt{3}}} \huge\text{)} = (x + 2)[/tex]
[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} = (x + 2)[/tex]
[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} - 2 =x[/tex]
[tex]\implies x = \underline{-2.6...} \ \text{and} \ \underline{-1.4...} \ \ \ \ (\text{Nearest tenth})[/tex]
Y-intercept of Parabola:Assume "x" as 0.
⇒ y = 3(0 + 2)² - 1⇒ y = 3(2)² - 1⇒ y = 3(4) - 1⇒ y = 12 - 1⇒ y = 11y-intercept = 11 ⇒ (0, 11)
Determining the direction of the parabola:Since the first cooeficient is positive (+3), the direction of the parabola will be upwards.
Determining the axis of symmetry line:Axis of symmetry line: x-coordinate of vertex
Axis of symmetry line: x = -2
Plot the following on the graph:
y-intercept ---> 11 -----> (0, 11)x-intercept(s) -----> -1.4 and -2.6 -------> (-1.4, 0) and (-2.6, 0)Vertex -------> (-2, -1)Axis of symmetry ----> x = -2Refer to graph attached.
Answer:
VertexVertex form of a quadratic equation:
[tex]y=a(x-h)^2+k\quad \textsf{where }(h,k)\:\textsf{is the vertex}[/tex]
Given equation: [tex]y=3(x+2)^2-1[/tex]
Therefore, the vertex is (-2, -1)
x-intercepts (zeros)The x-intercepts are when [tex]y=0[/tex]:
[tex]\implies 3(x+2)^2-1=0[/tex]
[tex]\implies 3(x+2)^2=1[/tex]
[tex]\implies (x+2)^2=\dfrac13[/tex]
[tex]\implies x+2=\pm\sqrt{\dfrac13}[/tex]
[tex]\implies x+2=\pm\dfrac{\sqrt{3}}{3}[/tex]
[tex]\implies x=-2\pm\dfrac{\sqrt{3}}{3}[/tex]
[tex]\implies x=\dfrac{-6\pm\sqrt{3}}{3}[/tex]
Therefore, the x-intercepts are at -2.6 and -1.4 (nearest tenth)
y-interceptThe y-intercept is when [tex]x=0[/tex]:
[tex]\implies 3(0+2)^2-1=11[/tex]
So the y-intercept is at (0, 11)
Plot the graphAs the leading coefficient is positive, the parabola will open upwards.Plot the vertex at (-2, -1)Plot the x-intercepts (-2.6, 0) and (-1.4, 0)Plot the y-intercept (0, 11)The axis of symmetry is the x-value of the vertex. Therefore, the parabola is symmetrical about x = -2
**You don't need to plot the axis of symmetry - I have added it so that it is easier to draw the curve**

[tex]5 = \frac{x}{3} + 2[/tex]
step by step please.
Answer:
9
Step-by-step explanation:
Given equation:
[tex]5 = \dfrac{x}{3} + 2[/tex]
To determine the solution (x) of the equation, we need to isolate it. To do this, we can subtract 2 both sides of the equation.
[tex]\implies 5 - 2 = \dfrac{x}{3} + 2 - 2[/tex]
[tex]\implies 3 = \dfrac{x}{3}[/tex]
To further isolate "x", we can use cross multiplication.
[tex]\implies 3 \times 3 = x[/tex]
Finally, simplify the expression on the left-hand-side to obtain the value of x.
[tex]\implies \boxed{9 = x}[/tex]

what does sin O = ?
Answer:
B) 3/5
----------------------------------------------------------------------------------------------------------
SolveSo, we know that tantheta is 0.75, or 3 quarters, but we have to find the value of sintheta. If there are 4 angles on a triangle, we can label them as BC and AB.[tex]because~of~the~angles\\BC = 3k\\AB = 4k[/tex]
Now, we must find the value of AC using the pythagoras theorem.⇒ (AB)² + (BC)² = (AC)²
in which because of AB and BC's values, goes into...
⇒ (4k)² + (3k)² = (AC)²
because of that ↑ you get the values of what is below.
⇒ (AC)² = 16 k² + 9 k²
add 16k and 9k for the result below.
⇒ (AC)² = 25 k²
⇒ AC = ±5k
Hmm. An angle cannot be negative, so turn 5k to positive 5k. Last but- not least, we have to find the sintheta.the sin is the side opposite to the angle, so find the hypotenuse and opposite angle.
[tex]Side~opposite~to~angletheta\\= BC(3k)\\\\Hypotenuse\\= AC(5k)[/tex]
That said → [tex]sintheta = \frac{BC}{AC} = \frac{3k}{5k} = \frac{3}{5}[/tex]

Hail is a form of precipitation when droplets of water freeze together in the cold upper reaches of the thunderstorms.
Thee chunks of that range from 5 to 15 cm can be round and jagged. Hail fall on the ground in a solid form they are often associated with tornadoes and certain parts of the world receive more hail than other parts do.
These frozen droplets of water when fall from the clouds get uplifted by wind and that adds another layer to them. The freezing occurs below the zero degrees at an altitude of 11,000 feet.
Mostly found in North America Nebraska, colorado and Wyoming states. and African regions in winter and South America in summer.
