Answer:
not a right triangle
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 12 and 12² = 144
7² + 10² = 49 + 100 = 149 ≠ 144
Then triangle is not right

Step-by-step explanation:
Use the given function to find the indicated value(s) of x. (Enter your answers as a comma-separated list.)
For f(x) = √2x + 2 − √x + 18, find x such that f(x) = −1.
Answer:
For f(x) = √(2·x + 2) - √(x + 18), at f(x) = -1 the possible x-values includes;
-0.757, -17.5
Step-by-step explanation:
Given that the function is f(x) = √(2·x + 2) - √(x + 18)
The value of 'x' when f(x) = -1, is given as follows;
-1 = √(2·x + 2) - √(x + 18)
-1² = (√(2·x + 2) - √(x + 18))² = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)
1 = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)
2·√(2·x + 2)×√(x + 18) = 3·x + 20 - 1 = 3·x + 19
2·x² + 38·x + 36 = (3·x + 19)/2
2·x² + 38·x + 36 - (3·x + 19)/2 = 0
4·x² + 73·x + 53 = 0
From which we get;
x = (-73 ± √(73² - 4 × 4 × 53))/(2 × 4)
x ≈ -0.757, and x ≈ -17.5

Answer:
Part A: One.
Part B: (3, 5)
Step-by-step explanation:
Part A: A solution to a pair of equations is generally where the two functions intersect. As we can see, a graph is provided, so things are facilitated. We can see that they only intersect once, which means only one answer.
Part B: The solution, which as we have learned is where the two lines intersect, is (3, 5), as that is, again, the point of intersection.

A line passes through the points (4, -1) and (2,3). What is the slope of the line?
-2. 2
1/2
-1/2
Answer:
-2
Step-by-step explanation:
To find the slope of a line with 2 given points, you use the formula
m=y2-y1/x2-x1
Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2
4/-2 equals -2
The slope is -2

A grocery store sells a bag of 5 oranges for $3.10. If Ishaque spent $2.48 on oranges, how many did he buy?
I’m struggling on question C
One way to find the midpoint is to start at either endpoint (A or B), and count how many spaces it takes to get to the other endpoint. You should count exactly 5 spaces. This means that the midpoint will have us travel 5/2 = 2.5 spaces when we start at either endpoint and walk to the other side.
If we start at point A and move 2.5 units up, then we'll arrive at (-2, 1.5)
If you start at point B (where the red x is) and move 2.5 units down, you'll get to (-2, 1.5)
The midpoint is located at (-2, 1.5)
------------------------------------------
Another method is to use the coordinates of A and B. Point A is located at (-2, -1) and point B is located at (-2, 4)
Focus on the x coordinates for now only. The x coordinates are -2 and -2, so they are the same in this case. Adding them up leads to -2+(-2) = -4. Then we divide by 2 to get -4/2 = -2. It turns out that if the coordinates are the same, then adding them up and dividing by two leads to the same coordinate value.
Now move onto the y coordinates. Points A and B have y coordinates of -1 and 4 respectively. They add to -1+4 = 3 and that cuts in half to 3/2 = 1.5
The results of -2 and 1.5 we got in the previous two paragraphs then immediately lead to the midpoint's exact location of (-2, 1.5)

Evaluate. 2.2^3 . 2^-5 .2^-1
A. -4
B, -8
C. 1/4
D. 1/8
Answer:
Step-by-step explanation:
2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 )
= 2^( 3 - 6 )
= 2^- 3
= 1 / 2^3
= 1 / 8
If
2 . 2^3 . 2^- 5 . 2^- 1
= 2^1 . 2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 + 1 )
= 2^( 3 - 5 )
= 2^- 2
= 1 / 2^2
= 1 / 4

You have just planted a new tree. To support the tree, you attach a wire from the trunk of th tree to a stake in the ground. Each wire has a length of 7 feet. Suppose you put the stakes in the ground 5 feet from the base of the trunk. Approximately how far up the trunk should you attach the wires?
Answer: 4.9 ft
Step-by-step explanation:
Given
Length of wire [tex]l=7\ ft[/tex]
Stake is at a distance of [tex]5\ ft[/tex] from the base of tree
suppose wire is attached y ft above the base of tree
from the figure, we can write
[tex]\Rightarrow 7^2=5^2+y^2\\\Rightarrow y^2=49-25\\\Rightarrow y=\sqrt{24}\\\Rightarrow y=4.89\approx 4.9\ ft[/tex]
suzanne is running a 5km race. so far she has ran 1,250m. how many more meters does she need to run to complete the race?
Answer: 3750 m
Step-by-step explanation:
Remember that there are different units; one is in km and the other is in m
I’ll go from km to m
1 km = 1000 m
Therefore 5 km = 5 x 1000 m
5km = 5000 m
Now, we just subtract to find how much more Suzanne have to run
5000 m - 1250 m = 3750 m

∛44x-7 -5=0 find the x
Answer:
x = 3.
Step-by-step explanation:
(∛44x - 7) - 5 = 0
Cube the expression.
44x - 7 - 125 = 0
Subtract.
44x - 132 = 0
Add 132 to both sides.
44x = 132
Divide by 44.
x = 3.
Proof:
(∛44x - 7) - 5 = 0
(∛44(3) - 7) - 5 = 0
(∛132 - 7) - 5 = 0
(∛125) - 5 = 0
5 - 5 = 0
0 = 0
Lucia compro 12 pares de media a 60 pesos cada una 7 remeras a 156 pesos cada una y 2 pantalones a 350 pesos cada uno.Si pago con 3000 pesos¿le sobro o le falto dinero?¿cuanto?
Answer:
A Lucia le sobró dinero y la cantidad que sobró es: 488 pesos.
Step-by-step explanation:
Para determinar si le faltó o le sobro dinero, debes determinar el costo total de lo que compró multiplicando el precio de cada artículo por la cantidad comprada y sumando estos valores:
(60*12)+(156*7)+(350*2)=720+1092+700=2512
Dado que pagó con 3000 pesos y el costo total de lo que compró es de 2512 pesos y este valor es menor que 3000 en 488 pesos, la respuesta es que le sobró dinero.
