Answer:

First, subtract 63 from 75 to find out how much it decreased.

75 - 63 = 12

Divide 12 by 75.

12 / 75 = 0.16

In percents, that is 16%.

He spent 16% less this month.

Hope this helps!

Consider the surface given by

Mazyrski [523]

This is just simple. For example you have a plane of the form x=a, then you just substitute x with a, and you'll get an equation with y and z only, hence you have a 2-d trace of the intersection. It is just similar for y=b and z=c.

(1) At z=1.5, 2x^2 + 5y^2 + 1.5^2 = 4
2x^2 + 5y^2 = 1.75
Now you have an ellipse in the z=1.5 plane as your trace.

(2) At x=1, 2(1)^2 + 5y^2 + z^2 = 4
5y^2 + z^2 = 2
Now you have an ellipse in the x=1 plane as your trace.

(3) At z=0, 2x^2 + 5y^2 + (0)^2 = 4
2x^2 + 5y^2 = 4
Now you have an ellipse in the z=0 plane as your trace.

(4) At y=0, 2x^2 + 5(0)^2 + z^2 = 4
2x^2 + z^2 = 4
Now you have an ellipse in the y=0 plane as your trace.

Secant TQ and tangent TR intersect at point T. Chord SR and chord PQ intersect at point V. Find the values of x and y. If necess

san4es73 [151]

Answer:

x=4, y=9.6

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

$TP X TQ=TR^2$

$9(9+12+x)=15^2\\9(21+x)=225\\189+9x=225\\9x=225-189\\9x=36\\x=4$

Next, we apply Theorem of Intersecting Chords

SV X VR=PV X VQ

5 X y = x X 12

Recall: x=4

5y=4 X 12

5y=48

y=48/5=9.6

Therefore: x=4, y=9.6

Using first principal find the gradient of the curve whose equation is y=x^5. show working pleas

Keith_Richards [23]

Answer:

The gradient of $y = x^{5}$ is $\frac{dy}{dx} = 5\cdot x^{4}$ .

Step-by-step explanation:

Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let $y = x^{5}$ , then the gradient of the curve is:

$\frac{dy}{dx} = 5\cdot x^{4}$ (1)

The gradient of $y = x^{5}$ is $\frac{dy}{dx} = 5\cdot x^{4}$ .

(solve for x ) −28−1/5n=3/5n

almond37 [142]

Answer:

$- 28 - \frac{1}{5} n = \frac{3}{5} n \\ - 28 = \frac{1}{5} n + \frac{3}{5} n \\ - 28 = \frac{4}{5} n \\ n = \frac{( - 28) \times 5}{4} \\ n = ( - 7) \times 5 \\ \boxed{ n = - 35}$

<u>n=-35</u> is the right answer.
