Hello there,
So we are trying to find out is the angle ∠BAC in degrees.
So what we are going to do is. . .25- (2x-10)°.
That answer would be -2x+35.
So ∠BAC= -2x+35°.Hope this helps.

Answer: The equation of the parabola is
.
Explanation:
It is given that the focus of the parabola is (-5,-5) and the directrix is y=7.
The standard form of the parabola is,

Where y=k-p is directrix and (h,k+p) is the focus.
Since focus is given,

On comparing,

.... (1)
The directrix is y=7.
.... (2)
Add equation (1) and (2),


Put this value in (1).

Put p= -6, h= -5 and k=1 in the standard form of the parabola.


Therefore, the equation of parabola is
.
PEMDAS.....parenthesis, exponents, multiplication/division, addition/subtraction
so step 2 is solving the exponents <==
Answer:
Step-by-step explanation:
a. 100005
1 x 1000000 + 0 x 100,000 + 0 x 10000 + 0 x 1000 + 0 x 100 + 0 x 10 + 5 x1
1 x 10^6 + 0 x 10^5 + 0 x 10^4 + 0 x 10^3 + 0 x 10^2 + 0 x 10^1 + 5 x 1
= 100,000 + 0 + 0 +0 +0 + 5
b. 84016
8 x 10000 + 4 x 1000 + 0 x 100 + 1 x 10 + 6 x 1
80000 + 4000 + 0 + 10 + 6
c. 9078
9 x 1000 + 0 x 100 + 7 x 10 + 8 x 1
9000 + 0 +7 + 8
d. 113
1 x 100 + 1 x 10 + 3 x 1
100 + 10 + 3
e. 75
7 x 10 + 5 x 1
70 + 5
