Answer: slope -1; y-intercept is 13, (0,13)
Step-by-step explanation:
We rewrite the function as y = -x + 13
y = mx + b; m is the slope, b is the intercept, by comparison, we found that the slope is -1, and the y-intercept is 13.
Put these numbers in descending order.
0.98
0.925
0.88
0.7
The descending values of the numbers is 0.98 > 0.925 > 0.88 > 0.7
Given data ,
Let the numbers be represented as A
Now , the value of A is
A = { 0.98 , 0.925 , 0.88 , 0.7 }
And , arranging in the descending order means from the greatest to the least value
So , the value of A is 0.98 > 0.925 > 0.88 > 0.7
Hence , the descending order is 0.98 > 0.925 > 0.88 > 0.7

Step-by-step explanation:
A triangle always has 180º
C is a right angle which is 90º. Proof is because of the square.
So now we have 90º left and 2 angles left.
90 ÷ 2 = 45
So your answer is 45º

Find the area of the following shape.
Answer:
Area = 9 cm²
Step-by-step explanation:
The shape given is a kite.
Area of a kite = ½(D1*D2)
Where,
D1 = 6 cm
D2 = 3 cm
Therefore:
Area = ½(6*3)
Area = ½(18)
Area = 9 cm²

A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

Angle P and angle Q make a
90° angle.
Angle P = 62°
Angle Q = 4x
What is the value of x?
Hope this helps
Substitute the values of angles P and Q in an equation that equals 90 degrees
62° + 4x = 90°
Then isolate the variable by first subtracting 62 from both sides
62 + 4x = 90 → 4x = 28
-62 -62
Then divide both sides by 4
4x = 28 → x = 7

Answer:
(-4,-4)
Step-by-step explanation:
Delta math
According to graph, the coordinates of the vertex of the parabola are (-4,-4).
What is parabola?"A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped."
Vertex of parabola"The vertex of a parabola is the point at the intersection of the parabola and its line of symmetry. For a parabola whose equation is given in standard form, the vertex will be the minimum (lowest point) of the graph and the maximum (highest point) of the graph.
After analysing the graph, the vertex of the parabola are (-4,-4)
