What is the solution to this equation 1^6 x =2
Alenkinab [10]
<h2>Greetings!</h2>

Anything to the power of 1 is still 1, because 1^{6} is simply 1 x 1 x 1 x 1 x 1 = 1 ect.

<h3>So this changes the equation to 1x = 2, which means that:</h3>

x = 2

<h2>Hope this helps!</h2>

8 3/8 = r- 2 1/3 how do i solve this equation by finding out what r is.
BaLLatris [955]
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.

Triangle GHK has an area of 117cm2. Write and solve an equation to find the height of the triangle GHK
stellarik [79]

Answer:

h=58.5/b

Step-by-step explanation:

This isn't necessarily possible, unless you know the base, but I can solve it with what we have, understanding the answer will contain variables:

The formula for the area of a triangle is A=1/2bh

117=(1/2)bh

58.5=bh

h=58.5/b

I'm not sure if this is the answer you were looking for, but I hope it helps

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near
professor190 [17]

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{b^2 - 4ac}{4a}

In this problem, the function is given by:

y = 2x² + 25x + 3.

Hence the coefficients are a = 2, b = 25, c = 3, then the coordinates of the vertex are given as follows:

  • x_v = -\frac{25}{2(2)} = -6.25
  • y_v = -\frac{25^2 - 4(2)(3)}{4(2)} = -75.13

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

Julia correctly estimated the value of 183 ÷ (76 – 15) + 29 by rounding each number to the nearest ten. What was Julia’s estimat
Vinvika [58]

Answer:

2 using PEMDAS

Step-by-step explanation:

First, I would round all numbers (to the nearest tenth).

183 rounds to 180

76 rounds to 80

15 rounds to 20

29 rounds to 30.

Now plug those numbers into the equation.

180/(80-20)+30

Using PEMDAS, I solve the parentheseis first.

80-20=60.

180/60+30

Then, add 60+30.

60+30=90.

you get 180/90.

180/90=2.
