Answer:
lesser x = -1.84lesser x = -8.16Step-by-step explanation:
Given the expression
[tex]\left(x+5\right)^2-10=0[/tex]
Add 10 to both sides
[tex]\left(x+5\right)^2-10+10=0+10[/tex]
Simplify
[tex]\left(x+5\right)^2=10[/tex]
[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
solve
[tex]x+5=\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=\sqrt{10}-5[/tex]
[tex]x=\sqrt{10}-5[/tex]
[tex]x=-1.8[/tex]
so
[tex]x+5=-\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=-\sqrt{10}-5[/tex]
Simplify
[tex]x=-\sqrt{10}-5[/tex]
[tex]\:x=-8.2[/tex]
As -1.84 > -8.16
so
lesser x = -1.84lesser x = -8.16Related Questions

Answer:
a = w/p
Step-by-step explanation:
To take a out of the fraction, we can multiply both sides by a to get ap = w. Now, we divide both sides by p to get a = w/p.
Answer:
a = w/p
Explanation:
Step 1: Multiply both sides by a.
ap = w
Step 2: Divide both sides by p.
ap/p = w/p
a = w/p

Denzel buys a basketball for $24 plus 7.5% tax. Mel buys a football for $20 plus 8% tax. What is the difference in the amount Dave and Mel paid, including tax?
Answers
Answer:
Dave paid $4.20 more than Mel
Step-by-step explanation:
Lets start with Dave:
Turn the % into a decimal - so 7.5 % would be 0.075
Then multiply it to the amount in cost to get the tax - 24 x 0.075 = 1. 80
Now add the tax to the total - 24 + 1.8 = $25. 80
Mel
Turn the % into a decimal - so 8 % would be 0.08
Then multiply it to the amount in cost to get the tax - 20 x 0.08 = 1. 60
Now add the tax to the total - 20 + 1.6 = $21.60
To find the difference subtract Dave's with Mel's
$25. 80 - $21.60 = $4.20

Dave makes 20% commission on all of his sales for the week. Last week Dave sold $1000. How much did Dave make?
Answers
Answer:
Dave will make $200 for the sales of $1000.
Step-by-step explanation:
Given are:
Rate of commission of Dave = 20%
Total sales = $1000
The amount that Dave will make will be obtained by calculating the 20% of total sales.
For that we will multiply the sales with 0.20
[tex]Commission = 20\%\ of\ Sales\\= 20\%\ of\ 1000\\=0.20 * 1000\\= 200[/tex]
Hence,
Dave will make $200 for the sales of $1000.

Answer:
The slope is undefined.
Hence, option C is true.
Step-by-step explanation:
The graph represents a vertical line.
We know that the slope of a vertical line is undefined.
Verification:
Taking two points
(0, -2)
(0, -4)
Finding the slope between (0, -2) and (0, -4)
slope = m = y₂-y₁ / x₂-x₁
= [(-4-(-2))] / [(0-0) ]
= [-4+2] / 0
= -2 / 0
= ∞
Thus, the slope is undefined.
Hence, option C is true.

A cone has a diameter labeled twelve centimeters and a height labeled thirty-two centimeters. Find the area of a vertical cross section through the center of the base of the cone.
Answers
Answer:
[tex]A=0.0192[/tex]
Step-by-step explanation:
Diameter labeled twelve centimetres D =12cm => 0.12
height labeled thirty-two centimetres H= 32cm => 0.32
Generally the vertical cross section of this cone is a triangle
Mathematically solving
Area of vertical cross section through the center of the base of the cone is given by [tex]A=1/2 D*height[/tex]
[tex]A=R*H[/tex]
Therefore
[tex]A=\frac{0.12}{2} *0.32[/tex]
[tex]A=0.06 *0.32[/tex]
[tex]A=0.0192[/tex]

Answer:
m∠b = 92 ; m∠c = 92
Step-by-step explanation:
∠b and ∠c both form supplementary angles with the 88° angle. I'll just choose b in this instance.
b + 88 = 180
b = 92
Now we know that ∠b is 92°.
Moreover, ∠c and ∠b are known as vertical angles meaning they are equivalent to each other. Therefore, ∠c is also 92°

Find the 64th term of the arithmetic sequence 2, -3, -8,
Answers
Answer:
[tex]a_{64} = -313[/tex]
Step-by-step explanation:[tex]a_{64} = 2 -135[/tex]
This is the Arithmetic Sequence Formula-> [tex]a_{n} = a_{1} + (n+1) d[/tex]
1) The d represents your difference of the equation. You can find it by finding a pattern between the three numbers given, which is -5
2) Now that we've found our difference, we can plug it into this lovely sequence we have [tex]a_{64} = a_{1} + (64-1) -5[/tex] (by the way, your n represents your term that you plug into the equation)
3) [tex]a_{64} = 2 + (64-1) -5[/tex] This also means that [tex]a_{1}[/tex] is our first term, which is 2
4) Simplify [tex]a_{64} = 2 + (63) -5[/tex] --> [tex]a_{64} = 2 +-315[/tex]
5) [tex]a_{64} = -313[/tex]
The formula is confusing at first, but it becomes easier once your learn the patterns!

A local grocery story has strawberries on sale for $1.45 per pound. How much would it cost to buy 5.5 pounds of strawberries? Round your answer to the nearest penny. Show your work on the sketchpad and type your answer below
Answers
Answer: The cost of 5.5 pounds strawberries =$ 7.98
Step-by-step explanation:
Given: A local grocery story has strawberries on sale for $1.45 per pound.
i.e. Cost for 1 pound strawberries = $1.45
Now, Cost of 5.5 pounds strawberries = 5.5 x (Cost for 1 pound strawberries)
= $ (5.5 x 1.45)
= $ 7.975 ≈ $ 7.98 [ Round to the nearest penny]
Hence, the cost of 5.5 pounds strawberries =$ 7.98
